#CMT# #/CMT# The method involves form-locking and/or frictional mechanical joining of metal sheets (1,2) and/or profile parts at one or more connecting sites, and thermally joining the connecting sites by pressure welding. #CMT# : #/CMT# An independent claim is also included for an automobile body segment for motor vehicle. #CMT#USE : #/CMT# For joining multiple metal sheets and/or profile parts. #CMT#ADVANTAGE : #/CMT# Ensures rapid repair of defective weld connection points without problem since the weld joints can be improved without maintaining a very difficult welding process window. Ensures easy and economical repair not only in product line but also during repair of already delivered motor vehicles at repair shops. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows the grinding pattern with the characteristic markings of punched rivet connection produced by joining method. 1,2 : Metal sheets 6 : Punch rivet. |
