A rule of thumb it to weld as hot as you can without burning through. So, depending on the metal thickness you're welding, you may travel 1" every 10 seconds. It just really depends, though. I would first start by welding on steel that's a bit thinner because it will .

TIG stands for Tungsten Inert Gas which is a welding technique done with the help of tungsten electrode for heating different metals. It is ideally preferred where the Chicago welder fails because of its limitation in doing the stainless steel soldering job. The TIG option can be deployed for doing the stainless steel welding .

To detect axial cracks (e.g. IGSCC) in stainless steel pipe welds with the weld cap in place, single matrix array probes in pulse-echo mode can be used to "skew" the sound beam under the weld cap. Since the sound beam essentially propagates in fine-grain base material, shear waves can reliably detect flaws at the near-side of the weld.

Oct 14, 2017· For example, stainless steel doesn't transfer heat as well as other metals, so it's easy to build up too much heat in the weld area, causing the steel to warp and reducing its corrosion resistance. To control the heat, reduce the current on the welding machine and speed up the movement of the torch.

TIG welding uses a torch with a solid tungsten electrode, an argon shielding gas, and a filler rod that gets dipped into the weld puddle. TIG is very similar to oxy acetylene welding since both use a filler rod to dip into the weld puddle. However, with TIG you can weld steel, stainless steel, aluminum, titanium, magnesium, and more.
