Some times the factories don't do much better. My brother in law bought a 78 Ramcharger brand new. 10 years later he was using it off road and the factory welded spring perch separated from the axle housing. The Ramcharger went sideways, and slid back down the hill he was climbing. Fortunately the RC didn't roll over and test the factory roll bar. Same issue, cold weld.
When I bought my 1977 Volare new in '76, the first time I changed oil I was shocked. The K-member halves were welded together with what appeared to be the MIG process and there were literally hundreds of "starts" the full length of the weld. Looked like a pincushion. That and undercoating on the bottom of the dash....this was not Chrysler's finest hour.
