PULSED LASER-TIG HYBRID WELDING PROCESS

摘要

The invention relates to a pulsed laser-TIG hybrid welding process which combines two energy sources with pulsed operation, having two using variants, depending on the leading process: pulsed TIG-laser with TIG as the leading process and pulsed laser-TIG with the leading laser beam, the process being applicable in various industrial fields for carrying out non-detachable joints of various categories of materials. According to the invention, the process combines two energy sources with pulsed operation: a pulsed laser beam () and a pulsed TIG arc (), respectively, in a common working zone, where the two processes interact and mutually influence each other, thereby producing positive synergistic effects on the characteristics of the welding joint () obtained in the base materials (), in particular in the attenuation of laser beam penetration variation, the process taking place under a permanent monitoring of the specific process parameters and geometric parameters: the angle between the two ends () and the hybrid distance (), while, depending on the type of the base materials (), the use of a laser protective gas released through a nozzle () or the use of an addition material may be required.
