A welding wire sequentially penetrates through the three pairs of guide wire couplings from right to left and then is connected with the conductive nozzle.

Description

technical field [0001] The invention relates to a gas shielded welding droplet transfer control device and a control method, in particular to a gas shielded welding droplet transfer control device and a control method based on the droplet resonance principle, belonging to the field of welding. Background technique [0002] With the continuous development of science and technology, the requirements for welding technology in various industries in our country are getting higher and higher, and the application of thin plates is increasing. Thin plates are more sensitive to the heat input in the welding process. Problems of burn-through, deformation and uneven weld formation. Therefore, it is necessary to reduce the welding current to reduce heat input when welding thin plates. However, under low current, the electromagnetic force and plasma flow force on the droplet are not strong enough, hindered by surface tension and spot force, the droplet transfer is a large (coarse) dropl...
