Abstract
A gas metal arc welding gun with a hollow tungsten electrode comprises a gun body, a welding wire (1) penetrating through the gun body and a wire feeding system (2) for conveying the welding wire (1). A nozzle (3) is arranged at the tail end of the gun body, and a conducting nozzle (4) is mounted in the gun body; the hollow tungsten electrode (5) is connected to the tail end of the conducting nozzle (4), and the welding wire (1) penetrating through the gun body penetrates through the conducting nozzle (4) and the hollow tungsten electrode (5); the tail end of the welding wire (1) extends out of the nozzle (3) by a certain distance. According to the gas metal arc welding gun, a welding electric arc is more stable, and the welding quality and the welding efficiency are both higher. The welding gun is reasonable in structure and convenient to maintain.
Description
Technical field
The present invention relates to gas metal-arc welding welding gun technical field, be specifically related to a kind of gas metal-arc welding welding gun with hollow tungsten electrode.
Background technology
Gas metal-arc welding is that welding field uses more a kind of welding method; its cardinal principle is exactly utilize the fusible welding wire sent to continuously as electrode; come filler wire and base metals using the stable arc between welding wire and welded piece as welding heat source, realize the connection of workpiece.In order to avoid welding the impact of high hot-zone by outside air, adopting protective gas to carry out real-time guard, ensureing the final mass of weld seam.
Gas metal-arc welding can be divided into welding and metal active gas welding by the kind according to protective gas, and the two is all widely used in the connection of each metalloid.Simplified summary, gas metal-arc welding has the advantages such as deposition efficiency is high, applied widely, economical and practical, and best with welding welding quality wherein.But in today that solder technology is growing, the welding efficiency of gas metal-arc welding still has much room for improvement, to adapt to the demand of the solder technology of high speed development now.
Summary of the invention
The object of this invention is to provide the gas metal-arc welding welding gun with hollow tungsten electrode that a kind of welding efficiency is high.
Object of the present invention is achieved through the following technical solutions:
A kind of gas metal-arc welding welding gun with hollow tungsten electrode; the wire feed system of the welding wire comprising rifle body and pass in rifle body and conveying welding wire; wherein rifle body end is nozzle; ignition tip is equiped with in rifle body; hollow tungsten electrode is connected with at ignition tip end; the welding wire passed in rifle body is through ignition tip and hollow tungsten electrode, and wire tip stretches out nozzle one segment distance.
Ignition tip of the present invention and hollow tungsten electrode are threaded connection.
The present invention, compared with existing gas metal-arc welding, because add a hollow tungsten electrode, makes except having electric arc between welding wire and workpiece; also an electric arc is there is between hollow tungsten electrode and workpiece; under the effect of twin arc, welding arc is more stable, and welding quality is higher.In addition, because two electric arcs are coordination, make this kind have higher current load power with the gas metal-arc welding welding gun of hollow tungsten electrode relative to conventional fused pole gas protecting welding gun, and then improve welding efficiency.This welding gun structure is rationally, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1-welding wire; 2-wire feed system; 3-nozzle; 4-ignition tip; 5-hollow tungsten electrode.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described, can better understand the present invention and can be implemented, but illustrated embodiment is not as a limitation of the invention to make those skilled in the art.
As shown in Figure 1, a kind of gas metal-arc welding welding gun with hollow tungsten electrode of the present invention, comprises the wire feed system 2 of rifle body, the welding wire passed in rifle body and conveying welding wire.Wherein rifle body end is nozzle 3, is equiped with ignition tip 4 in rifle body, and ignition tip is set with one and hollow tungsten electrode 5, and ignition tip 4 and hollow tungsten electrode 5 are threaded connection; Welding wire 1 passes in rifle body, and through ignition tip 4 and hollow tungsten electrode 5 center, welding wire 1 end stretches out nozzle 3 one segment distance.
During use, first workpiece to be welded is assembled, start the source of welding current and open protection gas cylinder switch, adjust welding parameter, rifle body is near workpiece to be welded, adopt the mode striking of contact starting, because ignition tip 4 passes to welding wire 1 electric current, namely electric arc burn between welding wire 1 and workpiece to be welded, because hollow tungsten electrode 5 is also connected with ignition tip 4, after nozzle 3 end arc ions reaches finite concentration, secondary electric arc is produced immediately between hollow tungsten electrode 5 and workpiece to be welded, under the acting in conjunction of two electric arcs, workpiece to be welded forms a molten bath, along with welding wire 1 is sent constantly into by wire feed system 2, under the protection of protective gas, welding gun moves forward, define a weld seam completed gradually, realize the connection of metal to be welded.Because two electric arc actings in conjunction are in a molten bath, make welding quality more stable, meanwhile, also improve welding efficiency.
Claims (2)
1. the gas metal-arc welding welding gun with hollow tungsten electrode; the wire feed system (2) of the welding wire (1) comprising rifle body and pass in rifle body and conveying welding wire (1); wherein rifle body end is nozzle (3); ignition tip (4) is equiped with in rifle body; it is characterized in that; hollow tungsten electrode (5) is connected with at ignition tip (4) end; the welding wire (1) passed in rifle body is through ignition tip (4) and hollow tungsten electrode (5), and welding wire (1) end stretches out nozzle (3) segment distance.
