Technology Of Tailor-Laser Welded Blanks Aluminum Alloys

The aluminum metal alloy laser welds the technical research and applications to are in the aviation, aerospace industry realm at the earliest stage. In recent years, the aluminum metal alloy laser welding technique have already got the application abroad in automobile make realm, being placed in the start stage still in the domestic.This text to suit to make the research that the automobile overlays the knothole 3 A21 aluminum manganese metal alloy lamella(1.5 mm) to carry on the welding craft and weld to deal with contact the microstructure and mechanical properties;Passed the roll system processing also, dealt with contact to microstructure and mechanical properties to the welding line on the further research.To the planks welding craft to experiment the result enunciation:Passed the laser welding to carry out the thick 3A21aluminum manganese metal alloy lamella(1.5 mm) welding successfully. The laser power density and the welding speeds are important craft parameters that acquires the good welding to sew.Deal with contact the microstructure and mechanical properties to study the enunciation to the welding:The anti-pulls the strength as 78% of the female material. The welding deals with contact to organize a bulky, it is main reason that results in the welding deal with contact the strength to lower that pore and hot influence areas soften.Pass the roll system processing research enunciation:Through roll system, the welding deals with contact 86% that the anti-pulls the strength as female material. The welding deals with contact the microstructure fine and process the hardening is main reason that results in the welding deal with contact the strength exaltation. Welding the craft and dealing with contact to the laser of that material research of microstructure and mechanical properties didn't yet appear in newspaper to lead.
