Abstract
An argon shielded arc welding torch with two tungsten electrodes is composed of main body, two electric conducting bodies parallel in the main body, two tungsten electrodes fixed to lower ends of said electric conducting bodies, two cable fastening screw bolts, and an insulating plate between two electric conducting bodies.
Description
Technical field:
The present invention relates to the improvement of argon tungsten-arc welding welding gun structure.
Background technology:
Argon tungsten-arc welding (TIG) since have welding quality height, process stabilization, controllability good, be suitable for advantage such as all position welding, be to use one of welding method very widely always.Its operation principle as shown in Figure 1.But have only a tungsten electrode in traditional TIG welding gun, because the intrinsic thermal capacity of tungsten electrode and the restriction of single arc pressure, its operable rated current is little, and then hot input quantity is little, the welding deposition rate is lower than many other welding methods.These shortcomings make traditional single tungsten electrode TIG weldering can only be applied to the backing welding of thin plate (below 3 millimeters) welding and slab.How welding under the prerequisite of original advantage at the single tungsten electrode TIG of reservation, improve its welding deposition rate and welding efficiency, and then the TIG weldering is expanded in the welding of middle thick-walled metal structure, is problem demanding prompt solution.
Summary of the invention:
The object of the present invention is to provide a kind of double-tungsten argon arc weldering welding gun, but this welding gun has bearing great current, improves the hot input quantity of welding and the characteristics of welding deposition rate.The present invention comprises welding torch body 1, airscoop shroud 2, air leaving cover 5, two electric conductors 6, two tungsten electrodes 8, two electricity supply cable fastening bolts 9, insulating trip 10; Airscoop shroud 2 is fixed on the upper end of welding torch body 1, airscoop shroud 2 is provided with air admission hole 7, air leaving cover 5 is fixed on the lower end of welding torch body 1, the upper end of two tungsten electrodes 8 is separately fixed at the lower end of two electric conductors 6, two electricity supply cable fastening bolts 9 are separately fixed at the upper end of two electric conductors 6, two electric conductors 6 vertically are set in parallel in the welding torch body 1, and the lower end of two tungsten electrodes 8 is arranged on the outside of air leaving cover 5 lower ends, and insulating trip 10 is arranged between two electric conductors 6 in the welding torch body 1.That the present invention has is simple in structure, can increase electric current, improve the hot input quantity and the welding deposition rate of welding, the advantage during the TIG weldering is expanded in the welding of thick-walled metal structure.Welding efficiency of the present invention is more than 1.2 times of traditional single tungsten electrode TIG welding method.
Description of drawings:
Fig. 1 is traditional single argon tungsten-arc welding (TIG) operation principle schematic diagram, and Fig. 2 is an overall structure schematic diagram of the present invention.
The specific embodiment:
The specific embodiment one: (referring to Fig. 2) present embodiment is made up of welding torch body 1, airscoop shroud 2, air leaving cover 5, two electric conductors 6, two tungsten electrodes 8, two electricity supply cable fastening bolts 9, insulating trips 10; Airscoop shroud 2 is fixed on the upper end of welding torch body 1, airscoop shroud 2 is provided with air admission hole 7, air leaving cover 5 is fixed on the lower end of welding torch body 1, the upper end of two tungsten electrodes 8 is separately fixed at the lower end of two electric conductors 6, two electricity supply cable fastening bolts 9 are separately fixed at the upper end of two electric conductors 6, two electric conductors 6 vertically are set in parallel in the welding torch body 1, and the lower end of two tungsten electrodes 8 is arranged on the outside of air leaving cover 5 lower ends, and insulating trip 10 is arranged between two electric conductors 6 in the welding torch body 1.
The specific embodiment two: the difference of (referring to Fig. 2) present embodiment and the specific embodiment one is, it has increased guide post 3 and roll adjustment leading screw 4, guide post 3 and roll adjustment leading screw 4 respectively with electric conductor 6 vertical settings, the middle part of guide post 3 is arranged in two electric conductors 6 and the insulating trip 10, guide post 3 is slidingly connected with electric conductor 6, the two ends of guide post 3 are fixed on the outer wall of welding torch body 1, the middle part of roll adjustment leading screw 4 is located in electric conductor 6 and the insulating trip 10, the two ends of roll adjustment leading screw 4 are located on the outer wall of welding torch body 1 of guide post 3 downsides, one side head of roll adjustment leading screw 4 is provided with turn-knob 11, roll adjustment leading screw 4 is threaded with two electric conductors 6, and the thread rotary orientation on the roll adjustment leading screw 4 of insulating trip 10 both sides is opposite each other.Adjustable range between two tungsten electrodes 8 is 1-10mm.
Welding torch body 1 of the present invention is to be threaded with airscoop shroud 2 and air leaving cover 5, adopt fastening bolt to fix between electricity supply cable and the electric conductor 6, roll adjustment leading screw 4 is made up of left-handed and leading screw dextrorotation, and rotating threaded shaft can make two distances between the tungsten electrode change, and is fit to the requirement of different welding conditions.It is isolated that left and right sides electric conductor is insulated sheet 10, can use different power supplys respectively.This welding gun belongs to the gas shiled welding gun, feeds argon gas by air admission hole when work, produces gaseous arc between tungsten electrode and workpiece, finishes welding process.
The two tungsten electrode TIG welding guns of the present invention adopt single rifle structure, and distance is adjustable continuously in the 1-10mm scope between two tungsten electrodes.When the distance of tungsten electrode hour (approximately<5mm), electric arc of two common generations of tungsten electrode, test shows: the electric arc that two tungsten electrodes produce (respectively being 150A) is than single tungsten electrode (300A), arc pressure has reduced nearly 1/2nd, the danger of welding bead burn through is also reduced greatly, can guarantee weldment not by the prerequisite of burn-through under, increase electric current, obtain the needed hot input quantity of high-speed welding, improved the deposition rate of welding.When level was welded, maximum deposition rate can reach 55g/min, is higher than traditional TIG and welds about 20%.In addition, two tungsten electrodes can adopt the different sources of welding current, realize effective control of welding process.For example, use pulse TIG welding to regulate the phase difference of two tungsten electrode electric currents, can in the welding of positions such as downhand welding, horizontal position welding, vertical position welding, obtain extraordinary welding effect.When the distance of regulating two tungsten electrodes is big (>8mm) time, tungsten electrode produces electric arc separately, can realize the method for the rush-harvesting and rush-planting welding in the tradition, (for example: preceding rifle preheating, back rifle welds), and because such welding gun is littler more flexible, so have bigger using value.
