Abstract

The invention provides pulsation welding equipment. The pulsation welding equipment comprises a preset current obtaining unit, a first wire feed speed calculating unit, a first background current calculating unit, a second background current calculating unit and a control unit. The control unit controls output based on first background current within the first scheduled period starting from switching on of a welding gun switch, and controls to enable the background current to gradually change from the first background current to second background current within the second scheduled period from ending of the first scheduled period to starting of the main welding stage. The welding quality can be effectively improved.

Description

[technical field] [0001] The invention relates to the field of welding, in particular to a welding device and a control method for welding by means of pulse welding. [Background technique] [0002] Welding equipment (also known as welding machines) has been widely used in various manufacturing industries. According to different welding methods, welding equipment can be divided into short-circuit transition and pulse welding. Pulse welding has the advantages of arc compression effect, arc concentration, and good stiffness, so it is widely used in thin plate welding (such as welding of non-ferrous metals such as stainless steel, steel, and titanium). Hereinafter, welding equipment that welds in a pulsed manner is referred to as pulse welding equipment. [0003] At present, there are mainly the following two welding methods when using pulse welding equipment for thin plate welding: (1) welding with low current (for example, the preset current is below 100A), and the wire feed...
