Problems solved by technology
In the initial stage of arc ignition, a lower wire feeding speed is used to feed the wire to facilitate energy matching and avoid wire collapse; although the existing technology can avoid wire collapse to a certain extent, the welding efficiency is also low, which is not conducive to Increase productivity
Especially for electric two-wheeled vehicles, tricycles, hardware industry, steel and wood furniture and other occasions that require a large number of thin-plate electric welding processes, the low efficiency of arc ignition has a great impact on the production of enterprises.

The present disclosure provides an arc ignition control method and device for extremely high-speed melting welding. The arc ignition control method includes a first stage, and the first stage includes: determining the basic energy required for arc ignition; And the first compensation amount is calculated based on the wire feeding speed when the current is generated; the second compensation amount is calculated according to the stick-out length of the welding wire when the welding wire is in contact with the base metal and the current is generated; it is determined according to the basic energy, the first compensation amount and the second compensation amount Initial arc energy; control the output of welding equipment according to the initial arc energy. The arc striking control method and device of the present disclosure can improve the success rate and efficiency of arc striking.
Description
technical field [0001] The present disclosure relates to the field of welding technology, in particular, to an energy control method for extremely high-speed fusion welding and an energy control device for extremely high-speed fusion welding. Background technique [0002] Arc welding is one of the most widely used welding types. It usually uses the heat generated by the arc discharge to melt the solder and the workpiece, the workpiece and the solder melt to form a molten pool, and the molten pool is cooled and solidified to form a weld. Very high-speed fusion welding is a relatively common type of arc welding. For arc welding, arc ignition is generally required, that is, the welding wire is in contact with the base metal instantaneously to generate current, thereby forming an arc. The energy of the welding power source, the wire feeding speed and the stick-out length of the welding wire will all have an impact on the arc striking process. Wherein, the wire feeding speed re...
