Brazing Holes In Sheet Metal

Use the right brazing rod material for the metal used in your project.

Brazing holes in sheet metal.

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 equipment in this project can be bought for as little as 30 dollars. Did you want to learn how to work around that and deliver a solid re. If brazing filler metal melts assembly is at proper temperature for brazing.

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. By comparison high temp soldering brazing is guaranteed to warp and buckle the metal. Brazing is similar to soldering but at higher temperatures. And with mig welding you risk blowing out more metal than you fill plus the weld can be as hard as a rock.

Use a torch that produces a high intensity flame. This leaves the hole open and results in a sound joint. Test the temperature by touching brazing filler metal to base metal. Bright metal surface is visible underneath.

Patching sheet metal holes using low temp solder. Recommended rods by metal type. Brazing is also much easier then welding it s a lot like using a glue gun. Brazed metal can also be stronger then w.

Here s a few tips on repairing rust holes in car body panels. The alloy is induced by heat to flow to the top of the joint pushing the flux out. 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. In this video im showing you the process i use to do small rust repairs where a complete panel.

Have you ever welded something so thin and worn out that all you do is blow holes in it. Brazing is a quick and inexpensive alternative to welding.
