Re: Welding Discussion
From the other thread:
"as I said I used the 7014 on really thin metal for practicing, what kinda frames were you working on? what changed? why do they only use mig on frames now? just to save costs? "
7014 (Hillbilly rod)
7014 by it self is not a bad rod, it's more about the operator. It's flat weld rod, no vertical or overhead. It welds so easy the user will not get the rod down were it belongs, so penetration is bad, same problem as MIG. People look at the pool behind the arc trying to get the weld to look good. The quality of the weld is from the penetration/pool in-front and both sides of the arc, get it right the weld will look good too.
what kinda frames, why do they only use mig on frames now?
Don't know if they use MIG on frames now or not. An outside vendor builds the frames now. 150 to 650 frame for Ford Econolines but they looked like stick welds when I retired 3 years ago.
"What changed"
Federal regulations are always the rules for anything that's safety related, so good luck looking that up.
I spent 2 summers (83,84) as a summer/vacation replacement/helper in the Government Regulations Coordinator's office. Just the binders that held the paperwork from the Gov. was bigger than a set of Encyclopedias. What a pita. From the torque on the lug nut to the glue on the rear-view mirror has a government spec. that has to be tracked and paperwork filed just in case the government wants to check.
IMHO that's the number one reason manufacturing is going over seas.
I just hope a true welder gets into this. How to weld dissimilar metals, TIG, stick welding alunimum, (yes, they make a rod for that) stainless, etc.
