What a crock of ****!




I know most auto manufactures prohibit gas welding the stuff. MIG or
TIG is OK and brass should not be a problem as long as the temp stays
low enough. Some of the HSLA's apparantly are highly corrosion
resistant as well.

Brazing high strength alloy steel components of automotive bodies is
STRICTLY FORBIDDEN. Mig and tig are acceptable if done to
specifications - spot welding is most common.




Simply because the slopeheads haven't built a robot to do it for them yet!

Q' What part of an aircraft would you want to use 4130 sheet steel for?


Ps I'd love to see a production car that has any TIG welding as part of
its constuction.
