Embodiment Construction

[0010] The pulse gas shielded welding base value current transition control method is realized by the following steps:

[0011] (1) Control the welding current waveform of pulse gas shielded welding, so that the welding current waveform enters the base value current stage, and forms molten droplets in the base value current stage;

[0012] (2) Control the welding current waveform of pulse gas shielded welding, so that the welding current waveform enters the peak current stage from the base value current stage;

[0013] (3) Control the welding current waveform of pulse gas shielded welding, so that the welding current waveform enters the transition current stage from the peak current stage, and completes the droplet transfer in the transition current stage;

[0014] (4) Control the welding current waveform of pulse gas shielded welding, so that the welding current waveform enters the base value current stage from the transition current stage;

[0015] During specific implement...

Abstract

The invention relates to a pulse gas shielded welding current control method, in particular to a pulse gas shielded base-value current transition control method, solving the problem that the traditional pulse gas shielded welding current control method always causes overlong welding current arc and overlarge heat input amount of welding seams. The method comprises the following steps: (1) a welding current waveform enters a base current stage; (2) the welding current waveform enters a crest current stage from the base current stage; (3) the welding current waveform enters a transition current stage from the crest current stage; and (4) the welding current waveform enters the base current stage from the transition current stage. By the pulse gas shielded weldin base-current transition control method, the problem that the traditional pulse gas shielded welding current control method always causes overlong welding current arc and overlarge heat input amount of the welding seams is solved effectively. The method is applicable to the pulse gas shielded welding current control.

Description

technical field [0001] The invention relates to a welding current control method for pulse gas shielded welding, in particular to a method for controlling the transition of base value current for pulse gas shielded welding. Background technique [0002] The welding current control method of traditional pulse gas shielded welding includes two stages: the base value current stage and the peak current stage. The droplet is formed in the base value current stage, and the droplet transfer is completed in the peak current stage. Using this welding current control method will easily lead to excessively long welding arc and excessive heat input of the weld seam, thus resulting in poor welding effect during thin plate welding and non-ferrous metal welding. For this reason, it is necessary to invent a new welding current control method for pulse gas shielded welding to solve the problems that the traditional pulse gas shielded welding welding current control method easily leads to exc...
