Control box 15 grade that control panel 20 is configured to keep with chassis 14 is separated, and controls the action of each several part forming TIG welding system 1.Such as, control panel 20 controls the actions such as the movement based on the slip of twin shaft slide block 12, chassis 14, the supply based on the filler wire of feedway 13.In addition, control panel 20 controls the electric power etc. of electric power or the supply from MC power supply 40 to filler wire supplied from the source of welding current 30 to electrode and mother metal B.
In addition, control panel 20 carries out storing welding condition and the control exporting welding condition.At this, control panel 20 carries out following control in weld job: welding condition be stored in the internal storage 21 of control panel 20, transmits to the external memory storage 151 being inserted into control box 15 welding condition be stored in internal storage 21.Specifically, control panel 20 is stored in every predetermined 1st time welding condition used in welding in internal storage 21, and is transferred to external memory storage 151 after predetermined 2nd time longer than the 1st time reads the welding condition be stored in internal storage 21.In the present embodiment, as an example of the 1st memory cell, internal storage 21 is used.In addition, as an example of memory cell, the 2nd memory cell, external memory storage 151 is used.
The explanation > of < welding condition
Then, the condition of weld job is described, is namely stored in welding condition in internal storage 21 and external memory storage 151.User can use control box 15 set or change welding condition, and welding condition comprises the data such as such as welding current, pulse current, MC electric current, weldingvoltage, two ends crest voltage, speed of welding, welding wire feeding speed, peak value welding wire feeding speed, hunting speed, vibration dwell time, oscillation amplitude, turning height, side-play amount.
Welding current is electrode in weld job and the electric current between mother metal B.In the present embodiment, welding current can be exchange, and also can be direct current.In addition, when welding current is direct current, welding current also can be pulse.Specifically, pulse output output content in " when directly welding " setting with " during vibration welding " is different.When being set as directly welding, according to the timing of pulse frequency, welding current is switched to low current (hereinafter referred to as reference current) and high electric current (hereinafter referred to as peak point current), becomes the welding of common pulse current.On the other hand, when being set as vibration welding, when vibration end during electrode vibration stops, being switched to peak point current.In addition, such as, because of the thickness of slab of mother metal B or kind etc., welding condition is different, and peak current value when therefore welding current is pulse, pulse period etc. can set according to environment during welding.
MC electric current is the electric current to filler wire energising in weld job.Weldingvoltage is the voltage in weld job between electrode and mother metal B.In addition, two ends crest voltage is electrode is added on weldingvoltage voltage in vibration end stopping phase.When vibration end stops, by being added the voltage of the setting value of two ends crest voltage in the setting value of weldingvoltage, carry out AVC control.
Speed of welding is the travel speed of the chassis 14 in weld job.When welding wire feeding speed is jogging (inching) and the weld job of filler wire, from the speed of feedway 13 feeding filler wire.Peak value welding wire feeding speed is the welding wire feeding speed of electrode when the end that vibrates stops, and in vibration end stops, welding wire feeding speed changes to the speed having increased and decreased the amount corresponding to the setting value of peak value welding wire feeding speed and obtained.
Hunting speed is the speed of the electrode of twin shaft slide block 12 when electrode is vibrated.Vibration dwell time is that electrode, in the time of the vibration end stopping of left end or right-hand member, has left end dwell time and right-hand member dwell time when electrode vibrate.Oscillation amplitude is the oscillation amplitude of the electrode of twin shaft slide block 12 when electrode is vibrated.In the present embodiment, an example of the welding condition changed as the elapsed time, uses oscillation amplitude.Oscillation amplitude will be described in detail later.
Turning height is the height risen along with the shape of groove face, is at the first Imitation い of groove profiling (Open) in detect for groove in threshold value.Turning height is according to the left end of vibration end and right-hand member and have left end turning height and right-hand member turning height.Side-play amount is electrode makes electrode movement during vibration end stops amount from vibration end, has left end side-play amount and right-hand member side-play amount according to vibration end.
The explanation > of < oscillation amplitude
Then, the oscillation amplitude as welding condition is described.Fig. 3 is the figure of the example for illustration of oscillation amplitude.As shown in Figure 3, the electrode that welding torch 11 keeps moves according to the moving direction (direction of arrow A 1) of chassis 14.Now, twin shaft slide block 12 such as carries out vibration along the direction of the direction of arrow B 1 and arrow B 2 and vibrates to make electrode, and the shape of the groove along mother metal B is welded accurately.As mentioned above, the distance at the two ends of vibration end during electrode vibration is oscillation amplitude.In the example shown in Fig. 3, as the example of oscillation amplitude, represent distance L1, the distance L2 at the two ends at the vibration end put sometime.
At this, because the welding position of mother metal B changes along with the shape of mother metal B, therefore oscillation amplitude also changes along with the process of time.Control panel 20 decides according to the shape of mother metal B should the amplitude of traveling electrode, controls twin shaft slide block 12 and electrode is vibrated based on determined amplitude.In addition, rise when welding starts, every the 1st time or the 2nd time, in internal storage 21 or external memory storage 151, store the oscillation amplitude that the corresponding moment determines by control panel 20.
The explanation > of the picture of < display part display
Then, the picture that the display part that description operation case 15 possesses shows.Fig. 4 is the figure of an example of the picture shown by display part illustrating control box 15.In the picture shown in Fig. 4, show " welding current ", " P electric current ", " hunting speed ", " speed of welding ", " left end stopping ", " moving to left ", " left upset is high ", " PW speed ", " weldingvoltage ", " MC electric current ", " oscillation amplitude ", " wire speed ", " right-hand member stopping ", " moving to right ", " right upset is high ", " two P voltage " as welding condition.Further, the setting value of each welding condition is displayed on by the word of each welding condition.
In the picture shown in Fig. 4, " welding current " is the setting value of welding current, " P electric current " is the setting value of the peak point current of pulse current welding where applicable, " hunting speed " is the setting value of hunting speed, " speed of welding " is the setting value of speed of welding, and " left end stopping " is the setting value of left end dwell time, and " moving to left " is the setting value of left end side-play amount, " left upset is high " is the setting value of left end turning height, and " PW speed " is the setting value of peak value welding wire feeding speed.In addition, " weldingvoltage " is the setting value of weldingvoltage, " MC electric current " is the setting value of MC electric current, " oscillation amplitude " is the setting value of oscillation amplitude, " wire speed " is the setting value of welding wire feeding speed, and " right-hand member stopping " is the setting value of right-hand member dwell time, and " moving to right " is the setting value of right-hand member side-play amount, " right upset is high " is the setting value of right-hand member turning height, and " two P voltage " is the setting value of two ends crest voltage.
And, in illustrated example, welding current is set to 100 amperes (units of electric current: A), peak point current is set to 0A, hunting speed is set to 100cm/min (cm per minute), speed of welding is set to 5.0cm/min, and left end dwell time is set to 1.0 seconds, and left end side-play amount is set to 0.0mm.In left end turning height, setting value is multiplied 0.05 and the numerical value that obtains becomes actual left end turning height (mm), when setting value is 5, is set to 0.25mm.In peak value welding wire feeding speed, setting value is multiplied 10 and the numerical value obtained becomes peak value welding wire feeding speed, when setting value is 0, is set to 0cm/min.In addition, weldingvoltage is set to 12.0 volts (units of voltage: V), MC electric current is set to 40A, oscillation amplitude is set to 15.0mm, welding wire feeding speed is set to 100cm/min, right-hand member dwell time be set to 1.0 seconds, right-hand member side-play amount is set to 0.0mm, in right-hand member turning height, setting value is multiplied 0.05 and the numerical value obtained becomes right turning height (mm), setting value is set to 0.25mm when being 5, and two ends crest voltage is set to 0.0V.At this, about the value that each welding condition shows user's setting or changes, about oscillation amplitude, as mentioned above, the value showing the elapsed time according to the shape of mother metal B and determine in control panel 20.
In addition, in the picture shown in Fig. 4, the word of " welding detects cooling water exception before starting " as the error message about cooling water, is shown.In addition, the literature record of " initial point terminates " carries out black and white conversion (background is black, and word is white) at the end of the process of initial point recovery welding torch 11 or chassis 14 etc. being returned to predetermined initial point.Further, in the picture shown in Fig. 4, such as, the project of " welding current " selected by user's pressing operation button etc., and user can also carry out the setting value operating to change welding current.
The explanation > of the storage means of < welding condition
Then, illustrate that welding condition is stored into the method for internal storage 21 and external memory storage 151 by control panel 20 in weld job.Fig. 5 is the flow chart illustrating example welding condition being stored into the method in internal storage 21 and external memory storage 151.At this, insert external memory storage 151 to control box 15.In addition, user, before beginning weld job or in weld job, is beneficial to control box 15 to carry out setting or the change of welding condition, in the display part display welding condition of control box 15.In addition, the servomotor controlling the position, speed etc. of welding torch 11 or chassis 14, when starting weld job, is connected initial points such as making welding torch 11 and is recovered by user.
First, if press the action button for accepting the operation starting weld job among the action button that possesses at control box 15 of user, then control panel 20 accepts the operation (step 101) that welding starts via control box 15.At this, if external memory storage 151 is not inserted into control box 15, then in the display part display mistake of control box 15.If control panel 20 has accepted the operation that welding starts, the action then controlling welding torch 11, chassis 14 etc. based on the welding condition preset starts weld job, and in internal storage 21, store the setting value (step 102) of moment (hereinafter referred to as welding start time) and the welding condition starting weld job.
Then, control panel 20, when have passed through predetermined 1st time from welding start time at every turn, stores the welding condition being used for weld job in internal storage 21.At this, control panel 20 determines whether to have passed through for the 1st time (step 103), when have passed through for the 1st time ("Yes" of step 103) at every turn, store in internal storage 21 be used for weld job welding condition, namely in the welding condition (step 104) that the corresponding moment sets.On the other hand, if not through the 1st time ("No" of step 103), then control panel 20 does not store welding condition in internal storage 21.
In addition, control panel 20, when have passed through predetermined 2nd time from welding start time at every turn, stores the welding condition that internal storage 21 stores in the external memory storage 151 of control box 15.At this, control panel 20 determines whether to have passed through for the 2nd time (step 105), when have passed through for the 2nd time at every turn (step 105 "Yes"), read the welding condition be stored in internal storage 21 in that moment, in external memory storage 151, store the welding condition (step 106) of reading.At this, external memory storage 151 stores welding condition with the form of master data and subdata, as subdata, using the moment every the 2nd time as sampled point, stores welding condition as the file by sampling time point segmentation.Further, cause in power supply disconnection etc. abend time, do not delete stored subdata but continue to preserve at external memory storage 151.On the other hand, if not through the 2nd time (step 105 "No"), control panel 20 does not store welding condition in external memory storage 151.
Such as, at this, if the 1st time was set to 1 minute, the 2nd time was set to 5 minutes, then from welding start time, just in internal storage 21, stored welding condition every 1 minute.In addition, every 5 minutes, externally memory 151 transmitted the data of the welding condition that internal storage 21 stores, and was stored in external memory storage 151.
Then, control panel 20 determines whether to have accepted the operation (step 107) stopping weld job.At this, such as, when user presses the action button for accepting the operation stopping weld job, control panel 20 accepts the operation (step 107 "Yes") that welding stops via control box 15, stops welding torch 11, chassis 14 etc. to stop weld job.In addition, control panel 20 stores the moment (hereinafter referred to as the welding stop timing) that stopped weld job and and in the welding condition (step 108) that this moment sets, terminates this handling process in internal storage 21.On the other hand, if do not accept the operation (step 107 "No") that welding stops, then transfer to step 103, then, control panel 20 stores welding condition every the 1st time in internal storage 21, stores welding condition every the 2nd time in external memory storage 151.
In addition, in the method shown in Fig. 5, user presses the action button for accepting the operation that weld job starts, thus while starting weld job, also starts the process storing welding condition, but be not limited to this structure.Such as, also can arrange separately for starting the action button stored.In addition, also can with weld start time welding current, weldingvoltage rising edge for opportunity, start by welding condition store process.In addition, if the action button started by pressing weld job also starts the stores processor of welding condition, then can prevent user from forgetting the situation of operation or processing mistake etc.Equally, expect the action button being pressed the operation for accepting weld job stopping by user, thus also stop the stores processor of welding condition.
In addition, interval, i.e. the 1st time, the 2nd time that store welding condition can be changed by user.Such as, if the 1st time was less than 1 second, then the data volume of the welding condition that will record is huge, under needing the long situation of carrying out more than half a day, sometimes cannot leave whole resume in external memory storage 151 at weld job.In addition, data volume is huger, more can lose the simplification of the operation confirming the record that user carries out.In addition, from the view point of the precision confirming record, if at least obtained the data of a welding condition every 600 seconds, then the trend of arc stability can be confirmed.Therefore, preferably in the scope of 1 second to 600 seconds, specified for the 1st time.
In addition, if using the timing every the 1st time that is stored in internal storage 21 as savepoint, then determined for the 2nd time using several point to the savepoint of tens of point as 1 group.At this, the quantity of the savepoint of control panel 20 when externally memory 151 transmits welding condition in the lump from internal storage 21 does not limit, but from the view point of confirming the viewpoint of the precision of record that user carries out, producing the danger of abnormal ending, be preferably 1 group and carry out in the lump externally memory 151 with the savepoint of less than 50 and transmit.
The routine > of the storage means of < welding condition
Then, the example of the method stored in internal storage 21 and external memory storage 151 is described.Fig. 6 (a) ~ (c) and Fig. 7 is the figure for illustration of storing the example of the method for welding condition in internal storage 21 and external memory storage 151.At this, the situation that the 1st time that illustrated is 1 minute, the 2nd time was 5 minutes.
Fig. 6 (a) is the figure of the example for illustration of the welding condition stored after 5 minutes from welding and starting.The data of the welding condition that the welding condition data representation of the internal storage 21 shown in Fig. 6 (a) stored 5 minutes periods every 1 minute from welding start time.Further, from welding start time after 5 minutes, externally memory 151 transmission is stored in the data of the welding condition in internal storage 21, is stored as master data and subdata.
