Heat the joint where the two pieces of metal will meet until the joint glows.
Brazing sheet metal with mapp gas.
A convenient method of preplacing filler metal is by using a brazing sheet an aluminum alloy base metal coated on one or both sides.
Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.
Position the metal as desired.
Some mapp torches use a separate oxygen cylinder.
Others rely on air to provide oxygen to the flame.
Used it to weld an exhaust bracket good for those types of repairs on the trail since it can secured in a small space.
Apply the brazing rod to the joint while continuing to heat the metal surfaces.
Like is mentioned they are good for welding or brazing small steel items.
Torch burns too much oxygen very expensive to operate.
If needed use clamps to secure the pieces in position.
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.
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.
The oxygen tank does not last long at all.
Light the welding torch and adjust the flame.
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.
The 7 minute burn time for an disposable oxygen bottle goes faster than you think.
