Brazing Holes In Sheet Metal

Brazing is a quick and inexpensive alternative to welding.

Brazing holes in sheet metal.

Braze welding unlike brazing goes beyond capillary action and deposits a strengthening thickness or bead of brazing material in braze weld. 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. The equipment in this project can be bought for as little as 30 dollars.

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. Use a torch that produces a high intensity flame. Use the right brazing rod material for the metal used in your project. Quick and easy brazing aluminum copper and nonferrous metals.

And with mig welding you risk blowing out more metal than you fill plus the weld can be as hard as a rock. In this video im showing you the process i use to do small rust repairs where a complete panel. Here s a few tips on repairing rust holes in car body panels. By comparison high temp soldering brazing is guaranteed to warp and buckle the metal.

The brazing rod should be melted by the heat of the metal pieces being joined not by direct contact with the flame of the torch. Recommended rods by metal type. Have you ever welded something so thin and worn out that all you do is blow holes in it. Brazed metal can also be stronger then w.

The alloy is induced by heat to flow to the top of the joint pushing the flux out. 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 also much easier then welding it s a lot like using a glue gun. Bright metal surface is visible underneath.

This leaves the hole open and results in a sound joint. Test the temperature by touching brazing filler metal to base metal.
