TIG Welding Cast Formed Steel to low carbon steel
Posted: Sat Sep 18, 2010 12:12 am
I did a spark test on this and it looks just like mild steel. It's 3/16 3x4 (+3/16) square and the mild steel square tubing is 1/8.. This piece slides over the 3x4 tube. I don't have anyway to test weld so Here's what I'm thinking: Twist up some .035 ER70 S6 MIG wire for filler (all I have is S2) and spending a good amount of time cleaning it. Tack it on all four sides. Start with about 100 amps and use a long post flow while making short 2" welds with cool down periods in between. I'll probably use a #10 cup with a gas lens.
This is a Fulton Swing away trailer hitch installation.
I was thinking I'd just MIG it but I don't think I'd get the penetration I will with the TIG.
Any thoughts?
Thanks
Steve
