To quickly link two pieces of metal (such as in a fillet weld/braze), you can tack little bits of filler into the corners to join the two pieces of metal before continuing the seam. I've done it before to link a steel shaft with mystery metal X that looked like steel but would just blow up when you started to melt it (I'm guessing its iron/bronze) and it held up fine. You can get 2 complete Tig outfits consisting of a machine, bottle carrier/holder, and foot pedal for about $200 CDN so secondhand is definitely the way to go if you are on a tight budget. The problem is that if you run too hot with the TIG torch and end up melting the parent metal a little bit you end up with microscopic bronze inclusions in the steel. You can pre-place the filler metal (in the form of a ring, washer, formed strip, or powder), or it can be fed during brazing. OSHA eTool. Mapp gas and butane torches can also be used for brazing and welding. are a few common issues that metalworkers who are not familiar with a TIG setup help you have the best experience while on the site. This reduces overheating through to the base metal. It really depends on what you need to do. Does anybody have any research or data to suggest why gas fillet brazing is ok, but tig brazing is not? OSHA Fact Sheet (Publication 3647), (2013). Flame distance: In proper torch brazing, the flame is held away from the fitting far enough so that the flame wraps around the entire circumference and length of the fitting to uniformly heat the entire joint, not just the top of the joint.
