LASER WELDING DEVICE AND ITS APPLICATION FOR WELDING OF COVER COMPOSED BY METAL SHEET OR THRUST ELEMENT FOR GLASS COVER AT CAR PASSENGER CABIN SIDE

摘要

FIELD: process engineering.;SUBSTANCE: invention relates to welding device for welding of metal sheet first part to its second part. This device comprises frame (5), support head (6) irradiating the laser beam (7) and nozzle (8) feeding the welding wire (9) configured for making of beaded weld along the joint between said first and second parts of metal sheet. Frame (5) supports clamping roller (10) configured to press one part to another one. Said clamping roller (10) is located upstream of laser beam (7) in direction (F) wherein it displaces along the joint. Frame (5) supports the second clamping roller (12) shifted relative to the position of said first clamping roller (10) in said direction (F) of laser beam (7).;EFFECT: higher quality of the weld.;9 cl, 7 dwg
