Brazing Holes In Sheet Metal

If the hole needs to contain a liquid a rubber washer can go on the sheet metal screw to render it water tight.

Brazing holes in sheet metal.

Heat the joint where the two pieces of metal will meet. Brazing is a quick and inexpensive alternative to welding. The kind of plug to use depends on how the thin metal is being used. In most cases an overlapped joint will be stronger and braze together easier than a.

The equipment in this project can be bought for as little as 30 dollars. If you are going to weld on thin sheet metal such as car body parts then you re going to have holes to weld from time to time. Steps use the wire brush or emery cloth to scuff the surface of the metal. 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.

Brazing is also much easier then welding it s a lot like using a glue gun. Brazed metal can also be stronger then welds. And for personal projects and small production runs brazing is much more cost effective. A filler for the holes is needed i used some soft copper from a pipe hanging fixture hammered flat it was a perfect thickness for this application.

Perhaps a simple rivet or sheet metal screw can be secured in the hole. This may be due to burning through the thin sheet metal welding molding holes fabrication or other reasons needed. Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. A third method of applying brazing filler metal is to use a paste mixture of flux and filler metal powder.

Using lineman s pliers the plug is cut to shape slowly snipping into a circle. Holes in thin metal can be filled with plugs. Then clean the surfaces using soapy water or a. Regardless of the reason you will have holes that need welded shut.

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