Welding Heat Sink/Dam

Anyone out there had any experience with either Eastwoods EW Anti Heat Compound or Coldshield Thermal Paste? I have some body panels on a 55 Chevy to do and there are some long welds.

Thanks in advance

It may work but nothing beats trimming the panels to fit and doing short tacks until the seam is complete. Take your time and don't overheat the joint. Hammer and dolly as you go to control shrinkage.

the stuff works well

 

You cannot avoid some warpage when welding since the weld always shrinks the metal. That stuff is next to useless as far as I'm concerned unless used to protect chrome or something near the weld. I wouldn't worry too much about over heating the weld either. There is no such thing unless you blow through or undercut. When mig welding, weld as hot as possible in short zaps. Gas or tig welding, weld a few inches at a time then hammer and dolly. This article might help:

Jim Bailie uses a spray, forget the name.

 

Right Guard?

 

A little trick I use is to tack everything together, then skip around and do small stitch welds. To prevent warpage I will keep a wet rag to quench as I go. Yes that does crystalize the weld, but on sheet metal it dosent make a difference. On anything thicker, air cooling is the only way to go. It just a different way comapred to the Eastwood stuff.

 

Tons of tack welds. I have done lots of panels without any of that stuff you mention.

 

A lot of far tacks followed by closer and closer tacks and then to short seam joints, that stuff is unnecessary you may as well use the Right Guard, be patient, I wouldn't use the water, some guys like it.
