Swing technology and skills of argon arc welding

1, argon arc welding swing method is divided into crank and mop. 2. The crank handle is to gently press the welding nozzle on the weld, and greatly shake the arm for welding. Its advantages are good weld protection, good quality, beautiful appearance, high product qualification rate, especially convenient overhead welding, and very beautiful appearance color can be obtained when welding stainless steel. Its disadvantage is that it is difficult to learn. Because of the large swing of the arm, it is impossible to weld where there are obstacles. 3. The mop is that the welding nozzle gently leans or leans against the weld, and the little finger or ring finger of the right hand also leans or leans against the workpiece. The arm swings slightly, and the welding handle is dragged for welding. Its advantages are easy to learn and good adaptability, but its disadvantages are that the forming and quality are not as good as that of crank, especially the overhead welding without crank is convenient, and it is difficult to get ideal color and shape when welding stainless steel.
