Push or pull: Here the rule is simple. “If it produces slag, you drag,” says Leisner. In other words, you drag the rod or wire when welding with a stick or flux-core wire welder. Otherwise, you push the wire with metal inert gas (MIG) welding. Work angle: With wire welding, hold the gun at a 10 to 15 angle into the direction you are pushing the weld.
Reciproing wire feed gas metal arc welding (RWF-GMAW) is a low heat input, precisely controlled variation of the GMAW process. With the RWF-GMAW process the wire is reciproed in and out of the weld pool. The wire motion is synchronized with the current waveform to produce a weld that is characterized as having minimal if …
Most wire feed welders are going to have at least 2 knobs on the front of the machine. One is the voltage knob, and the other is your wire speed feed. When you’re learning mig welding you want to get comfortable with these settings. When you’re welding on
Butt welding these with a mig I think is pretty hard. If you can lap joint it, it will be a ton easier. What I do is 1 inch, flip the pipe over, do 1 inch and repeat. It seems that after 1 inch it gets too hot and burns through. I am not by any means a professional welder.
12/2/2012· Exhaust pipes are very hard to weld most are coated with a thin layer of a material to prevent rust which will have to be burnt off and on top of that it is a very thin metal to start with. Add to that the dirt from the road I think it best if you purchase a new pipe and practice on the old pipe.
Got to agree, unless you are going to be welding enough stainless to justify the investment in new wire and gas that could turn into some expensive welding. If there is not much load on the weld and you are not concerned with appearance however the ER70S-6, while certainly not the correct wire, will weld fairly well to the stainless.
