Method of butt joints laser welding with fixed power density, heat input and gas mixture

摘要

The method of butt joints laser welding of plates, carried out as one-side welding, in the atmosphere of shielding gas, characterized in that it is carried out by laser melting of the contact area of plates by means of a laser beam at power density of 1,5x10 5 W/cm 2 and at heat input of welding 990 J/mm, simultaneously applying a gas mixture flow composed of 95% argon and 5% carbon dioxide.
