1. Ordinary manual argon arc welding is used for flat welding and pulsed argon arc welding is used for fish scale welding.

2. Horizontal welding Horizontal plate welding is generally called flat welding. The welding position with weld inclination of 0 ~ 5 and weld rotation angle of 85 ~ 95 is called flat welding position, and the welding at flat welding position is called flat welding. This welding position belongs to the easiest welding position among all welding positions.

3. Fish-scale welding is a process method of welding, which is named because its welding plane is fish-scale.
