Wire feeding steady-state welding method for solid-state laser welding machine in high-latitude area

The invention discloses a wire feeding steady-state welding method for a solid-state laser welding machine in a high-latitude area. A steel coil to be produced during cold rolling needs to be flattened during hot rolling, and then the plate surface problem caused by the steel coil is eliminated for use. The method comprises the following steps that 1) the tail part of rolled upper coiled strip steel is fixed and prepared, and the head part of uncoiled new upper coiled strip steel is prepared; 2) the head and the tail are subjected to cutting off treatment by using a pair of welding machine scissors, and centering treatment is conducted; 3) welding parameters of the welding machine are adjusted, and a wire feeding trolley is adjusted for weld joint welding; and 4) after welding is completed, a cupping experiment is conducted to check weld joint quality; the thickness of the strip steel is 2 mm-6 mm, the welding power parameter and the welding defocusing amount of the welding machine inthe step 3 are adjusted t
