Brazing Sheet Metal With Mapp Gas

If needed use clamps to secure the pieces in position.

Brazing sheet metal with mapp gas.

I also have the small oxy propane mapp gas torched too. Position the metal as desired. Like is mentioned they are good for welding or brazing small steel items. Apply the brazing rod to the joint while continuing to heat the metal surfaces.

The 7 minute burn time for an disposable oxygen bottle goes faster than you think. Some mapp torches use a separate oxygen cylinder. Touch the flame to the work pieces and move in a small circle to melt the material at the weld zone. Torch burns too much oxygen very expensive to operate.

Others rely on air to provide oxygen to the flame. The oxygen tank does not last long at all. Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. If you lean out the oxygen to conserve it the mapp gas burns dirty does not get hot enough and produces large amounts of soot that sticks to your metal.

A convenient method of preplacing filler metal is by using a brazing sheet an aluminum alloy base metal coated on one or both sides.

In most cases an overlapped joint will be stronger and braze together easier than a gapped joint. Brazing is distinguished from welding because it uses an intermediary material usually a copper zinc alloy to join the two metal pieces rather than melting the pieces.

The process of brazing refers to the use of gas generated heat 800 degrees f and an iron free filler such as aluminum to join to different metals. Used it to weld an exhaust bracket good for those types of repairs on the trail since it can secured in a small space. Light the welding torch and adjust the flame.
