Abstract

The invention relates to a gas blowing protective device used during stainless steel sheet pulse laser welding. The device comprises a side gas blowing protection part installed on a collimating focusing head and is characterized in that the side gas blowing protection part comprises a first adjusting plate, a rotary rod, a slider and a side gas blowing pipe; the first adjusting plate is fixed on the side wall of the collimating focusing head and can be adjusted up and down; the rotary rod is arranged at the lower end of the first adjusting plate in a rotary manner and the angle of swing relative to the first adjusting plate can be adjusted; the slider is fixed on the outer side wall of the rotary rod and the axial position of the slider along the length direction relative to the rotary rod can be adjusted; the side gas blowing pipe is fixed on the slider in a penetrating manner and can be adjusted along the thickness direction relative to the slider. The gas blowing protective device used during stainless steel sheet pulse laser welding is convenient in adjustment of height and angular positions. After the protective device is adopted, side gas blowing can be adjusted to an optimum position, so that welded product weld surfaces are oxidation-free and have good gloss. The invention also relates to a welding process.

Description

technical field [0001] The invention relates to a gas blowing protection device for pulse laser welding of thin plate stainless steel and a welding process. Background technique [0002] Laser welding has become an advanced welding method in modern industry. Due to its high precision, less deformation, high efficiency, welding of difficult-to-weld materials and good processing flexibility, laser welding has become more and more widely used, from aerospace, The fields of automobiles and shipbuilding expand to the field of home appliances. Laser welding is considered to be a promising material processing technology due to its advantages of high energy density, large weld depth-to-width ratio, small heat-affected zone, good welding quality, and easy automation. [0003] Blowing protection is an essential process in laser welding. Splashes and other fumes generated during laser welding can easily contaminate the focusing mirror. The metal vapor and splashed particles deposite...
