Brazing Sheet Metal With Mapp Gas

Apply the brazing rod to the joint while continuing to heat the metal surfaces.

Brazing sheet metal with mapp gas.

Heat the joint where the two pieces of metal will meet until the joint glows. Position the metal as desired. Used it to weld an exhaust bracket good for those types of repairs on the trail since it can secured in a small space. The oxygen tank does not last long at all.

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.

A convenient method of preplacing filler metal is by using a brazing sheet an aluminum alloy base metal coated on one or both sides. I also have the small oxy propane mapp gas torched too. In most cases an overlapped joint will be stronger and braze together easier than a gapped joint. Torch burns too much oxygen very expensive to operate.

Others rely on air to provide oxygen to the flame. The 7 minute burn time for an disposable oxygen bottle goes faster than you think. Heat sources include a propane or mapp gas a turbo tip. Touch the flame to the work pieces and move in a small circle to melt the material at the weld zone.

Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. Some mapp torches use a separate oxygen cylinder. You can t braze dirty sooty material.
