Abstract

The invention relates to the technical field of welding, in particular to pulse welding equipment and a pulse welding control device and method. The pulse welding control method includes the steps that whether a short-circuit phenomenon occurs in a first pulse period of pulse welding or not is determined; when the short-circuit phenomenon occurs in the first pulse period, whether the short-circuitphenomenon continues to a second pulse period of the pulse welding or not is determined, and the second pulse period is adjacent to the first pulse period; and when the short-circuit phenomenon continues to the second pulse period, pulse parameters to be adjusted in the second pulse period are adjusted to increase welding pulse energy in the second pulse period. According to the pulse welding control method, the pulse parameters in the second pulse period can be adjusted, so that phenomena of welding spatter and welding wire binding are reduced, and the stability and welding quality in the welding process are improved.

Description

technical field [0001] The present disclosure relates to the field of welding technology, in particular to a pulse welding device, a pulse welding control device and a control method. Background technique [0002] Pulse welding means that the base metal to be welded is placed between two heating elements, and the current is applied to make the heating element generate a pulse of strong heat energy in a very short time, so as to realize the melting and welding of the base metal. Among them, MIG pulse welding (Metal Inert Gas Arc Welding) uses inert gas as the shielding gas of solid welding wire, while MAG pulse welding (Metal Active Gas Arc Welding) uses active gas as the shielding gas of solid welding wire. [0003] At present, during the use of MIG pulse welding and MAG pulse welding, if a short circuit occurs and continues to the next pulse cycle, it will affect the normal droplet of the welding wire in the next pulse cycle and cause larger particles Welding spatter, even...
