Welding is like practicing martial arts. The first thing to do is to have as table chassis, that is, a stable "horse step". When the center of gravity is unstable, it is difficult to weld a good weld when shaking.

1. Stable center of gravity

2. Welding gun stability

Handshaking will cause tungsten electrode to burn and form tungsten inclusion in the molten pool. The weld edges are irregular and the fish scales are uneven. We can control the spray gun by contacting the weldment with the little finger and ring finger, or stick the ceramic nozzle of argon arc welding to the work piece, and then adjust the length of tungsten electrode to 3-5mm according to the weld depth.

3. Wire feeding stability

The wire feeding method shall be adjusted according to the size of weld groove. If the groove is small, the welding wire can be fed continuously in the center of the molten pool. When the weld width is large, point wire feeding on both sides shall be adopted
