Does all chrome moly tubing need to be Tig'd?

admin

Looking at a mounting kit for a fiberglass front end on my current project car. Problem is it is made out of chrome moly. Don't  have the size/gauge of the tubing, but it is smaller than roll bar stuff. Thanks,RussRIP Mallory, we miss you.

Reply:I would not pass up the opprtunity to TIG some 4130. Chromoly welds so nice I'd tig it just for fun. But, no you you don't have to tig it.Last edited by fortyonethirty; 05-05-2011 at 11:36 AM.Ian TannerKawasaki KX450 and many other fine tools

Reply:I welded lots of 4130 high pressure pipe for oil field use with MIG and Spray Arc. Pre heat to about 500 and use ER70S wire.Two turn tables and a microphone.
