Welding of copper tube and stainless steel pipe, and welding by oxyacetylene welding? Specific steps please teachers advice.
Stainless steel and copper welding is not very good, must have good heat, stainless steel do not roast (a little too red, dark red line) and then use the copper dip and borax, melt into the weld line
You can use argon arc welding, gas welding is very rare now.
Look at the refrigerator repair, how to use Freon after perfusion of borax and copper electrode in welding, do, or let him give welding.
A gas welder intermediate title should not be a problem, it's easy and good welding welding welding of copper and stainless steel tubes, first with the two butt welding in metal luster, two tube interface to find it, the copper electrode heating flux welding stick red, and red copper welding or borax, welding two the mouth should be covered, heated to stainless steel in red red red brass electrode can also have electrodes, electric heating electrodes can, it will slowly experience welding.
