Process for controlling the welding current as a function of welding speed in arc welding equipment |
摘要 |
A welding speed-dependent voltage (11) is added to a variable fixed voltage (13), to control the welding current as a function of welding speed in DC arc welding equipment, for the continuous welding of longitudinal seams of tube-shaped metal bands. In addition, the sum (15) of speed-dependent voltage (11) and variable fixed voltage (13) is superimposed by a pulsed DC voltage by a summing amplifier (28).
