1. Stable center of gravity

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.

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

The welding process used for submerged arc welded straight seam steel pipe is submerged arc welding technology, which adopts filler welding and particle protection flux submerged arc. The diameter of production can reach 1500mm. LSAW is the English abbreviation of submerged arc welded straight seam steel pipe. The production process of submerged arc welded straight seam steel pipe includes JCOE forming technology and coil forming submerged arc welding technology. When the diameter is large, two steel plates may be used for rolling, which will form the phenomenon of double welds.

Gas welding is a welding method that uses the flame generated by themixed combustion of combustible gas and combustion supporting gas asthe heat source to melt the weldment and welding material and realizeatomic bonding. Electric welding uses electric energy to pressurize,heat, or both, with or without filler material to achieve atomicbonding of weldments.
