ABSTRACT:
In the process of arc welding with electrode wire feed there are many parameters which influence the quality of the welded joint. The welding system proposed provides considerable quality improvement, particularly in short-circuiting arc welding, reduces the dependence of the welding process upon the skill of the welder and greatly simplifies setting of the apparatus. A characteristic regulating parameter of the welding process is regulated so that the mean arc power remains substantially constant. Embodiments given by way of example illustrate ways of measuring and controlling the mean arc power, which, according to the insight on which the invention is based, is the factor which determines quality.
