PURPOSE: A welding method of stainless steel is provided to prevent the deformation of a product without the degradation of thermal stress strength by contactless laser welding. CONSTITUTION: A welding method of stainless steel comprises the next step. A thin filler metal(20) is inserted between two stainless steels. A contactless laser welder(30) injects laser beam to the contact surface of stainless steels. A filler metal is filled in the contact surface for brazing in a blazing furnace. The filler metal filled in the contact surface is frozen. |
