Abstract
Some basic schematics are analyzed of stabilization of arc excitation and running in metal-electrode arc welding with weld formation in portions, in particular using a low-amperage arc. Shown is the rationality of making up the welding circuit of several independently controlled loops which provide the conductance of the arc gap, main arc running, control of the capacitor discharge in the arc gap by means of capacitive or inductive contours connected directly into the welding circuit.
Keywords: arc welding, welding arc, arc exiting, arc stability, stability, pilot arc, portion heat input, welding circuit, investigations
