Brazing Holes In Sheet Metal

Brazing is similar to soldering but at higher temperatures.

Brazing holes in sheet metal.

Apply this paste to the areas on the metal pieces that will be joined using the brush. For these types of holes i start by cleaning the area around the hole with an angle grinder and flap disc. Use the right brazing rod material for the metal used in your project. The key tip is to make sure you take the time to setup your welder for nice flat spot welds and leave time for the metal to cool between each weld.

Have you ever welded something so thin and worn out that all you do is blow holes in it. There are a few different brazing systems out there. The easiest holes to fill are small holes about the diameter of a pen or smaller. Brazing as we ve seen uses the principle of capillary action to distribute the molten filler metal between the surfaces of the base metals.

By comparison high temp soldering brazing is guaranteed to warp and buckle the metal. Brazing means melting an alloy to join two metals. Brazing requires less energy than welding and can be used to join dissimilar metals. My favorite is low temperature brazing using an alloy called hts 735 ii.

Using the same tools and techniques as sweat soldering copper pipe this is the best way i know of doing a permanent almost invisible repair to sheet metal. Therefore during the brazing process you should take care to maintain a clearance between the base metals to allow capillary action to work most effectively. Mix a small amount of flux with water to form a paste. Did you want to learn how to work around that and deliver a solid re.
