Abstract

The invention provides a burn-back energy matching control method used for a digital welding machine. The burn-back energy matching control method used for the digital welding machine mainly includesthe steps that a wire feed speed function and a welding wire diameter are obtained; a virtual wire feed speed function is determined according to the wire feed speed function and the welding wire diameter, wherein when the welding wire diameter is larger than or equal to a preset value, the function value of the virtual wire feed speed function is larger than or equal to the function value of thewire feed speed function, and when the welding wire diameter is smaller than the preset value, the function value of the virtual wire feed speed function is smaller than or equal to the function valueof the wire feed speed function; and a response is made to a welding gun switch releasing signal, the wire feed speed is controlled according to the wire feed speed function, and the welding parameter matched with the welding current is controlled according to the virtual wire feed speed function. By means of the burn-back energy matching control method used for the digital welding machine, the welding quality can be effectively improved.

Description

technical field [0001] The present disclosure relates to the technical field of arc welding, and in particular, relates to a burnback energy matching control method for a digital welding machine capable of adjusting welding energy according to the diameter of a welding wire. Background technique [0002] Welding is widely used as a common connection method in boilers, pressure vessels, ships, bridges, wind turbine towers, oil and gas pipelines and other fields. There are many welding methods in industry, such as MI pulse gas arc welding, carbon dioxide gas arc welding (GMAW), carbon dioxide flux cored arc welding (FCAW), submerged arc welding (SAW), manual arc welding (SMAW) and tungsten gas shielded arc welding (GTAW), etc. [0003] In the related art, there are often welding quality problems caused by the mismatch between the welding energy and the diameter of the welding wire. For example, the arc is too short in the burnback stage due to too low energy in the thick wir...
