Brazing Holes In Sheet Metal

Quick and easy brazing aluminum copper and nonferrous metals.

Brazing holes in sheet metal.

And with mig welding you risk blowing out more metal than you fill plus the weld can be as hard as a rock. Have you ever welded something so thin and worn out that all you do is blow holes in it. Brazing is also much easier then welding it s a lot like using a glue gun. Brazed metal can also be stronger then w.

This leaves the hole open and results in a sound joint. Brazing is a quick and inexpensive alternative to welding. Did you want to learn how to work around that and deliver a solid re. Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.

The alloy is induced by heat to flow to the top of the joint pushing the flux out. Bright metal surface is visible underneath. Patching sheet metal holes using low temp solder. In this video im showing you the process i use to do small rust repairs where a complete panel.

By comparison high temp soldering brazing is guaranteed to warp and buckle the metal. Finally brazing fluxes have a tendency to cause hydrogen embrittlement in the metal adjacent to brazed joints and this can cause cracking in that metal as panels vibration cycle over miles and time. Brazing is similar to soldering but at higher temperatures. 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.

Here s a few tips on repairing rust holes in car body panels. The equipment in this project can be bought for as little as 30 dollars. Recommended rods by metal type. If brazing filler metal melts assembly is at proper temperature for brazing.

Test the temperature by touching brazing filler metal to base metal. Use a torch that produces a high intensity flame.
