The influence of the parameters such as surface treatment state, laser output power, welding speed, protective atmosphere, and pulse frequency on the welding quality was studied.
Temperature control means using thyristor surge phase shifter using nitrogen atmosphere furnace used to seal welding, excellent sealing properties.
控温方式采用可控硅移相调压，采用氮气保护气氛，炉体采用全密封焊接，密封性能优良。
