Is It Done This Way
Hi Guys
Just want to run this by you and see if I'm headed in the right directions.
When mig-welding a joint, I should follow these steps
1st. Clean the metal to be mig welded.
2nd. Srpay with joint will Weld-thru coating.
3rd. Mig weld the joint.
4th. Brush-on Seam Sealer over the new weld.
Finally, Spray etching primer over the Seam Sealer.
Is that the way its done guys. In that order?
This newbie needs all the help he can get before he jumps into the pool.
Any other suggestions will be greatly welcomed.
Thanks guys
GOD Bless

Meh, I may clean up the weld a bit, no fancy sprays or anything. If you're welding two thick pieces at a 90 degree angle, I'd cut some of the metal away to make a bevel so the weld holds better. I would focus more on the sound/conistancy/speed fo the welds. Just get a bunch of scrap metal and go nuts.

Thats depends if you are welding a "butt joint" or laping panels and using spot welds. No need for weld thru priner for a "butt joint" as it will be a contaminate and weaken the weld. Keeping the area clean will give greater results. The keyto welding buttjoints is taking your time. Let the weld cool to toutch before you startagain. Also start in another location to keep the heat fromwarping the panel. On lap joints where you will be usingspot welds, this is agood place to use weld thru(zinc) primer.Spray all surfaces that will be in contact with each other and let dry, keep the can shook up often as the metal will quickly settle. This will protect the metal under the laps when they aresandwiched together. Again, take your time. A number of clamps is also handy. Good luck.
