Brazing Sheet Metal With Mapp Gas

Some mapp torches use a separate oxygen cylinder.

Brazing sheet metal with mapp gas. Heat the joint where the two pieces of metal will meet until the joint glows. Torch burns too much oxygen very expensive to operate. The 7 minute burn time for an disposable oxygen bottle goes faster than you think. You can t braze dirty sooty material.

Apply the brazing rod to the joint while continuing to heat the metal surfaces. A convenient method of preplacing filler metal is by using a brazing sheet an aluminum alloy base metal coated on one or both sides. Like is mentioned they are good for welding or brazing small steel items. Used it to weld an exhaust bracket good for those types of repairs on the trail since it can secured in a small space.

In most cases an overlapped joint will be stronger and braze together easier than a gapped joint. 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. The oxygen tank does not last long at all. Heat sources include a propane or mapp gas a turbo tip.

Others rely on air to provide oxygen to the flame. 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. Touch the flame to the work pieces and move in a small circle to melt the material at the weld zone.

Position the metal as desired. Light the welding torch and adjust the flame. Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.
