Economics: Wall Mountain Company: Oxy-Acetylene Welding -

Oxy-acetylene welding is not only an excellent method of joining thinner gauge metals, it's also the best "first step" to understanding the fundamentals of welding that makes more modern processes like stick, tig, mig and flux core easier to learn.

Topics:
+Oxy-Act Welding covers equipment set-up, adjusting the regulators, lighting the torch and adjusting the flame. We even sneak in a little theory on why a neutral flame purges oxygen from the weld area.
+Beginning with starting and moving the molten puddle, then adding filler metal, close-up demonstrations with slow motion and inserted arrows point out exactly where to watch the molten weld puddle.
+Close-up video of the actual welds, with detailed explanations, demonstrates the characteristics of the molten metal and weld buildup for welding in the flat, horizontal and vertical positions.
+Metal preparation, joint fit-up and welding techniques are demonstrated for butt, lap, T and corner joints, focusing on penetration and amount of weld buildup.
