Welding With A Gas Torch.

…“When I show it to him he nods and slowly goes over and sets the regulators for his gas torch. Then he looks at the tip and selects another one. Absolutely no hurry. He picks up a steel filler rod and I wonder if he’s actually going to try to weld that thin metal. Sheet metal I don’t weld. I braze it with a brass rod. When I try to weld it I punch holes in it and then have to patch them up with huge blobs of filler rod. "Aren’t you going to braze it?" I ask. .. "No," he says. Talkative fellow. .. He sparks the torch, and sets a tiny little blue flame and then, it’s hard to describe, actually dances the torch and the rod in separate little rhythms over the thin sheet metal, the whole spot a uniform luminous orange-yellow, dropping the torch and filler rod down at the exact right moment and then removing them. No holes. You can hardly see the weld. "That’s beautiful," I say.” (Cont. Next)
North 6th Street, Business District, Grants Pass, OR. Ms Jan Aijian has granted permission for ZMMquality.org to display this photo here. I hope she will soon send more photos which, like this one, that illustrates the welder striking his torch (sparks but no flame), the welder working, and the welder’s gas cylinders, etc as described in these ZMM passages.
