![]() ![]() Then I got over the terrible sound it makes and realized it was a pretty cool, simple way of welding stainless. My first reaction to stainless FCAW was “woah, this is all wrong!”… but then after I looked at the bead, I was surprised that it was actually pretty good. Then you’ll develop a feel for understanding where the wire needs to be instead of where the pool is. Lay down a few inches of bead, then stop to see how it’s coming out. I’d recommend just laying down a few practice beads to get the hang of it before doing your real welds. If you try to control the puddle, you’re likely to move too slow and your weld bead will be ugly. It kind of sounds like if you were to run MIG without shielding gas, in my opinion.Īctually, trying to watch the melt pool will probably just distract you and get you to mess up. The arc isn’t smooth and steady like it is with MIG. One of the things that you’ll immediately notice is that the arc is totally different with FCAW.Įvery time I’ve done it, it’s been extremely crackly. How FCAW Stainless Welding is Different from MIG It’s obviously nowhere near as clean, pretty, and strong as a good TIG weld.It’s not just a matter of cleaning the slag, but there’s also a higher risk of getting slag inclusions in the metal. As with any FCAW process, you’ll get slag that protects the weld.For stainless, you generally need to weld electrode positive. If your welder is REALLY cheap, you might only have the option of running electrode negative, which is what’s used for carbon steel welding. ![]() This means it’s a total pain for jobs like exhaust pipes, where you need to weld in all positions.
