The 20 th century and the 70 th century are mainly used for welding thin-wall materials and low-speed welding, and the welding process belongs to a heat conduction type, namely, the surface of a workpiece is heated by laser radiation, the surface heat is diffused inwards through heat conduction, and the workpiece is melted to form a specific molten pool by controlling parameters such as the width, the energy, the peak power, the repetition frequency and the like of laser pulses. Due to the unique advantages, the welding method is successfully applied to the precise welding of micro and small parts.
The light welding process usually uses inert gas to protect the molten pool, and the protection can not be considered when the surface oxidation of certain materials is negligible during welding, but helium, argon, nitrogen and other gases are usually used for protection in most application occasions, so that the workpiece is prevented from being oxidized during the welding process.
Nitrogen is the least expensive as a shielding gas, but is not suitable for certain types of stainless steel welding, mainly due to metallurgical problems, such as absorption, which sometimes create porosity in the lap joint area.
