Detailed Description
The invention is described in further detail below with reference to the following figures and detailed description:
example 1
The embodiment 1 describes a welding parameter adjusting method of a welding machine applied to welding of a tube panel wall, and aims to solve the technical problems that the welding parameter adjusting process of the existing welding machine before welding of the tube panel wall is troublesome, the adjusting difficulty is high, and the production efficiency is influenced.
As shown in FIG. 1, the welding parameter adjusting method of the welding machine applied to the welding of the tube screen wall comprises the following steps:
when the welding direction of the welding gun is downward, triggering and calling one of the tube panel wall welding databases from a plurality of existing tube panel wall welding databases by pressing a first trigger selection button;
or when the welding direction of the welding gun is upward, triggering and calling one of the tube panel wall welding databases from the existing tube panel wall welding databases by pressing a second trigger selection button.
In addition, the welding parameter adjusting method of the welding machine applied to the welding of the tube screen wall in the embodiment of the invention further comprises the following steps:
when the welding direction of the welding gun is downward, pressing the first trigger selection button again, and triggering and calling another tube panel wall welding database from the existing tube panel wall welding databases;
or when the welding direction of the welding gun is upward, pressing the second trigger selection button again, and triggering and calling another tube panel wall welding database from the existing tube panel wall welding databases.
When the welding direction of the welding gun is determined, the corresponding trigger selection button is continuously pressed, and a welding database suitable for the material of the pipe screen to be welded can be selected from the existing pipe screen wall welding database.
For the sake of intuitive operation, in practical applications the first trigger selection button is labeled as "gun up" button and the second trigger selection button is labeled as "gun down" button, as shown in fig. 2 and table 1.
Wherein, table 1 shows the corresponding table of the combination of the welding orientation and the material of the welding wire in this embodiment.
TABLE 1
As can be seen from FIG. 2 and Table 1, when the "gun up" button is pressed, indicating that the welding direction of the welding gun is downward, the indicator light (indicated by a circle) corresponding to the material "ER 50-6" of the welding wire is on the side of the "gun up" when the welding direction of the welding gun is downward;
at this point, the first trigger selection button triggers and invokes the weld database of "ER 50-6" appropriate tube wall material.
By pressing the "gun up" button again, the first toggle selection button toggle triggers from the existing multiple tube panel wall weld database and invokes another tube panel wall weld database, such as the appropriate weld database corresponding to "ER 50-B2".
By analogy, by continuously pressing the first trigger selection button, the tube panel wall welding database suitable for the material of the tube panel wall to be welded can be triggered and called from the existing multiple tube panel wall welding databases.
Similarly, when the 'gun off' button is pressed, the welding direction of the welding gun is upward at the moment, and an indicator lamp (represented by a circle) corresponding to the welding wire material 'ER 50-6' above the side of the 'gun off' is turned on at the moment;
at this point, the second trigger selection button triggers and invokes the weld database of "ER 50-6" appropriate tube wall material.
By pressing the "gun down" button again, the second trigger selection button toggles from the existing multiple tube panel wall weld database and invokes another tube panel wall weld database, such as the appropriate weld database corresponding to "ER 50-B2".
By analogy, by continuously pressing the second trigger selection button, the tube panel wall welding database suitable for the material of the tube panel wall to be welded can be triggered and called from the existing multiple tube panel wall welding databases.
In addition, the welding parameter adjusting method of the welding machine further comprises the step of generating a welding database of each tube panel wall in advance. These pre-generated tube panel wall weld databases each correspond to a high alloy material commonly used in the boiler industry.
The pre-generated tube panel wall welding database is a welding parameter database which is respectively set when the tube panel wall made of each material is welded in different welding directions, wherein the current control waveform in each welding parameter database is respectively set.
Since the current control waveforms in the flat welding and the overhead welding are set separately in this embodiment, the welding adjustment is simple, spatter is less, and the weld bead formation (flattening uniformity, stable penetration) is good, as compared with the conventional setting of the same waveform (compromise waveform).
In addition, since the method of example 1 is classified according to the material of the tube panel (i.e., the high alloy material) and the welding direction, a welding database suitable for the material of the tube panel is prepared in advance.
Therefore, before welding the tube panel wall, in this embodiment 1, the welding database suitable for the material of the tube panel wall to be welded is triggered and called only by means of the corresponding trigger selection button (the "upper gun" or "lower gun" button) according to the welding direction, and after a suitable welding current and a suitable welding voltage are selected, welding is performed, so that the welding parameters are adjusted simply and conveniently, and the production efficiency is improved.
In addition, in the tube panel wall welding process, when the welding direction of a welding gun is changed due to the replacement of a certain welding machine and other reasons, the welding parameters of the welding machine are also easily adjusted, and the specific adjusting process is as follows:
when the welding direction of the welding gun is changed, according to the changed welding direction of the welding gun, the trigger selection button is used for triggering and calling the tube panel wall welding database which is suitable for the current tube panel wall material from the existing tube panel wall welding databases.
Specifically, when the changed welding direction is downward, the first trigger selection button is used for triggering and calling the tube panel wall welding database suitable for the current tube panel wall material from the existing tube panel wall welding databases.
Similarly, when the changed welding direction is upward, the second trigger selection button is used for triggering and calling the tube panel wall welding database suitable for the current tube panel wall material from the existing tube panel wall welding databases.
In addition, when the tube panel wall material changes, the welding parameters of the corresponding welding machine are also easily adjusted, and the method specifically comprises the following steps:
when the material of the tube screen wall changes, the corresponding trigger selection buttons are utilized to trigger and call the tube screen wall welding database suitable for the current material of the tube screen wall from the existing multiple tube screen wall welding databases.
The trigger selection buttons adopted before and after the material change of the tube screen wall are the same trigger selection button.
For example, assuming that a welding gun of a certain welding machine performs downward welding before the material of the tube panel changes, the first trigger selection button (i.e., "gun up" button) is used to trigger and call the welding database applicable to the tube panel before the material changes.
When the material of the tube screen wall changes, the welding gun of the welding machine still faces downwards, and at the moment, the welding gun is switched to the welding parameter library suitable for the tube screen wall with the changed material only by utilizing the first trigger selection button (namely the 'gun feeding' button).
It can be seen from the above process that no matter the material of the tube panel or the welding direction of the welding gun is changed, the corresponding tube panel welding database is selected by using the corresponding trigger selection button, and the welding can be performed again.
Therefore, the embodiment 1 of the invention also effectively solves the problem that a large amount of manpower and debugging time are consumed when welding parameters of a welding machine are adjusted due to changes of welding directions, tube panel wall materials and the like during the existing tube panel wall welding.
Example 2
The embodiment 2 describes a welding parameter adjusting system of a welding machine applied to welding of a pipe screen wall. The system is a welding parameter adjusting system corresponding to the welding parameter adjusting method of the welding machine for welding the tube barrier in the embodiment 1.
Specifically, this be applied to welding machine welding parameter governing system of pipe screen wall welding includes:
a plurality of tube panel wall weld databases;
the first trigger selection button is configured to trigger and call one of the tube panel wall welding databases from a plurality of existing tube panel wall welding databases when the welding direction of the welding gun is downward; and
and the second trigger selection button is configured to trigger and call one of the tube panel welding databases from the existing tube panel welding databases when the welding direction of the welding gun is upward.
Wherein, the welding database of each tube panel wall needs to be generated in advance.
In this embodiment 2, the tube panel wall welding database is a welding parameter database respectively set for each material of the tube panel wall in different welding directions; wherein, the current control waveform in each welding parameter library is respectively set.
Since the current control waveforms in the flat welding and the overhead welding are set separately in this embodiment, the welding adjustment is simple, spatter is less, and the weld bead formation (flattening uniformity, stable penetration) is good, as compared with the conventional setting of the same waveform (compromise waveform).
In addition, since the system of the embodiment 2 is divided according to the material of the tube panel (i.e. the high alloy material) and the welding direction, a welding database suitable for the material of the tube panel is prepared in advance.
Therefore, before welding the tube panel wall, in embodiment 2, the welding database suitable for the material of the tube panel wall to be welded is triggered and called only by means of the corresponding trigger selection button (the "upper gun" or "lower gun" button) according to the welding direction, and after a suitable welding current and a suitable welding voltage are selected, welding is performed, so that the welding parameters are adjusted simply and conveniently, and the production efficiency is improved.
It can be seen that this embodiment 2 has still solved effectively when current pipe screen wall welding because welding position, pipe screen wall material etc. change, when readjusting welding machine welding parameter, need consume a large amount of manpowers and debugging time's problem.
It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
