METHOD FOR CHANGING A WELDING PROCESS DURING A WELDING PROCESS AND FOR HEATING INTO A WELDING PROCESS

摘要

The invention relates to a method for changing a welding process during a welding process, wherein the change from a performed welding process to a subsequent welding process of a short circuit between the one melting welding wire and a workpiece is performed. In order to achieve a welding process with high process stability, it is provided that with recognition of the short circuit of the welding process carried out, the welding wire is conveyed on to a defined period of time (32) in the conveying direction and then, depending on a threshold value (34) of the welding current (I) of the following welding process Promotion of the welding wire (9) is stopped, whereupon, upon reaching the threshold value (34) of the welding current (I) of the welding wire (9) is promoted in the opposite direction to start the following welding process.
