First of all, to just come in the friend to introduce the introduction of argon arc welding, two bonded welding, plasma welding, laser welding, the working principle of each and its advantages. Convenient to learn or to enter the processing industry bosses to choose. Argon arc welding argon arc welding arc using high-pressure breakdown of the arc starting method

The main reason why novice welders can't match the current and voltage is that they don't know the relationship between the two, and they don't know what role they play. Current is to control the weld depth (current can also be understood as the wire feed speed, the greater the current, under the condition of constant voltage).

当焊丝伸出长度过大时,焊丝会发生过热而成段成段的熔断,致使焊接过程不稳定,飞溅增大,焊缝成形不良,气体对熔池的保护也被减弱。 如果是二保焊连弧焊打底焊时
