The disclosure provides a welding system, an arc welding control device and an arc welding control method, and relates to the field of welding technology. The arc welding control method is used in the first stage before the main welding and the second stage after the main welding. Both the first stage and the second stage are stages in which the wire feeding amount and welding parameters are constantly changing and include multiple transition periods. The arc welding control method of the present disclosure includes: at the moment of switching from the current transition period to the next transition period, adjusting the current wire feeding speed to the target wire feeding speed according to the preset change amount; determining the target welding speed matching the target wire feeding speed Parameter; adjust the current welding parameters to the target welding parameters.
Description
technical field [0001] The present disclosure relates to the field of welding technology, and in particular, to a welding system, an arc welding control device, and an arc welding control method. Background technique [0002] With the widespread use of welding technology, people's requirements for welding quality are getting higher and higher, among which arc welding is a more common type of welding. Existing arc welding mainly includes pulse welding, non-pulse welding, double-pulse welding, etc., and the process of arc welding generally includes an arc initiation stage, a main welding stage and a burn-back stage. [0003] In the prior art, in the arc striking stage and the burn-back stage, the wire feeding speed is constantly changing, and the welding parameters are also continuously updated. The mismatch between the welding parameters and the wire feeding amount will affect the timing of the droplet falling off, resulting in a poor transition effect and ultimately affecti...
