Problems solved by technology
[0005] 1. The arc start is unstable during continuous spot welding, resulting in the incompleteness of a single solder joint, which affects the appearance of the entire fish scale weld seam
[0006] 2. When arcing in spot welding, the requirements on the arcing position and angle are relatively strict. If the angle is too large, it may cause wire collapse and affect the solder joints.

The present disclosure provides a method and device for controlling wire feeding pulse of a welding power supply. The wire feeding pulsation control method of the welding power supply includes: setting the wire feeding speed according to the wire feeding pulsation frequency; determining the wire feeding rising time of the wire feeding rising process according to the wire feeding pulsating frequency; and / or dividing the wire feeding falling process into Multi-stage wire feeding drop control. This solution controls the wire feeding up process and / or the wire feeding down process under the given wire feeding pulsation frequency, which can shorten the wire feeding up response time and / or the wire feeding down response time, thereby improving the welding efficiency.
Description
technical field [0001] The present disclosure relates to the field of welding technology, and in particular, relates to a method and device for controlling wire feeding pulse of a welding power supply. Background technique [0002] As an important means of industrial manufacturing, welding has always played an important role in my country's economic construction. [0003] With the progress of the times, the bicycle-sharing industry has developed rapidly in the past two years. At present, there has been a wave of bicycle-sharing in various large and medium-sized cities, and the bicycle industry has developed rapidly. [0004] At present, the bicycle industry is mainly based on short welds with thin plate fish scale patterns. The competition in the industry is relatively fierce, and manufacturers have high requirements for welding efficiency. Most manufacturers adopt the automatic continuous spot welding method for fish scale welding of bicycle part welds. This automatic cont...
