Abstract

Disclosed is a fuse wire argon tungsten-arc welding method. When direct-current fuse wire argon tungsten-arc welding is adopted, a fuse wire argon tungsten-arc welding gun is connected with the negative pole of a direct-current fuse wire argon tungsten-arc welding power source; a fuse wire feeder is connected with the positive pole of the direct-current fuse wire argon tungsten-arc welding power source through a fuse wire current adjuster; and a workpiece is connected with the fuse wire feeder and the fuse wire current adjuster in parallel through a welding current adjuster and is connected to the positive pole of the direct-current fuse wire argon tungsten-arc welding power source. The fuse wire current and the welding current can be set by adjusting the fuse wire current adjuster and the welding current adjuster respectively. The globular transfer manner of fuse wire argon tungsten-arc welding can be one of drop transfer, meso-spray transfer and spray transfer. The method can be used for welding steel and various non-ferrous metal materials.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a high-efficiency tungsten argon arc welding method using molten liquid metal as a filling material. Background technique [0002] Tungsten argon arc welding (TIG welding) uses non-melting tungsten as the electrode to establish an arc between the electrode and the workpiece for welding. The arc combustion is very stable, with stable arc, no spatter, high welding quality, and can weld almost any metal and alloy. It is a very widely used welding method. However, the welding efficiency of this welding method is low, and it is usually only used for thin plate welding and backing welding of thick plates. TIG welding can be performed without filler wire or with filler wire. The wire filling method can be manual wire feeding or automatic wire feeding. The filled welding wire melts in the arc, enters the molten pool metal, and forms a weld after solidification. The weldi...
