Brazing is also much easier then welding it s a lot like using a glue gun.
Brazing holes in sheet metal.
And for personal projects and small production runs brazing is much more cost effective.
The equipment in this project can be bought for as little as 30 dollars.
Steps use the wire brush or emery cloth to scuff the surface of the metal.
Holes in thin metal can be filled with plugs.
In most cases an overlapped joint will be stronger and braze together easier than a.
Heat the joint where the two pieces of metal will meet.
Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.
Brazing is a quick and inexpensive alternative to welding.
Perhaps a simple rivet or sheet metal screw can be secured in the hole.
For thicker sheet metal an old copper penny might be a quick source of material.
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.
Using lineman s pliers the plug is cut to shape slowly snipping into a circle.
Heat treatable or core alloys composed mainly of manganese or magnesium are also used.
Position the metal as desired.
A convenient method of preplacing filler metal is by using a brazing sheet an aluminum alloy base metal coated on one or both sides.
Then clean the surfaces using soapy water or a.
Regardless of the reason you will have holes that need welded shut.
A third method of applying brazing filler metal is to use a paste mixture of flux and filler metal powder.
If the hole needs to contain a liquid a rubber washer can go on the sheet metal screw to render it water tight.
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.
This may be due to burning through the thin sheet metal welding molding holes fabrication or other reasons needed.
