Embodiment 1
[0017] Example 1: Combining figure 1 , the present invention is a TIG power supply-assisted dual-TIG composite heat source welding equipment, which is composed of a main TIG power supply, a TIG main welding torch, a wire guide, a secondary TIG power supply, a wire feeding device and a workpiece, and is characterized in that: the main TIG power supply Connect the TIG main welding torch and the workpiece respectively, the main TIG power supply, TIG main welding torch, main welding arc and workpiece constitute the main welding circuit; the auxiliary TIG power supply connects the guide wire nozzle and the workpiece respectively, and the inside of the guide wire nozzle penetrates the wire sent by the wire feeding device. Welding wire, wire guide nozzle, auxiliary TIG power supply, workpiece and welding pool constitute a hot wire circuit, and the wire feeding device is insulated from the workpiece.

Embodiment 2
[0019] Example 2: Combining Figure 1-Figure 5 , the present invention is based on the low welding efficiency of traditional argon tungsten arc welding, the limited ability of the tungsten electrode to carry current, which limits its application in the field of thick plates and surfacing welding, and proposes a hot wire under the action of dual TIG composite power supply Welding Technology. Use the resistance heat or arc heat generated by the auxiliary TIG power supply to heat the welding wire to improve the welding heat input as a whole to make up for the limitation of heat input caused by the limited tungsten load capacity of argon tungsten arc welding; at the same time, the dual TIG composite power supply is adopted, The power capacity requirement on the TIG power supply is eased, the service life of the tungsten electrode is improved, and the production efficiency is improved. Since the heat of the composite heat source is concentrated to the end of the welding wire, the ...
Embodiment 3
[0022] Example 3: Binding Figure 1-Figure 5 , the present invention introduces a secondary TIG power supply in the tungsten argon arc welding system. First, the wire feeding device and the welding wire are insulated from the workpiece, and the two electrodes of the secondary TIG power supply are respectively connected to the wire feeding nozzle and the workpiece to form a conductive circuit, such as figure 1 shown. At the beginning of the welding process, connect the main welding circuit, ignite the main arc to preheat the workpiece for 1-2 seconds, then feed the welding wire through the wire feeding device, and connect the hot wire circuit when the end of the welding wire is 5-8mm away from the workpiece. Under the action of the arc plasma generated by the arc, the auxiliary arc is easily ignited between the end of the welding wire and the workpiece. Under the action of the heat generated by the arc, the end of the welding wire melts and forms a droplet. The heating effect ...
