Brazing holes in sheet metal. A small piece sheet metal can be brazed in place to cover larger holes. Base metal erosion or alloying when the filler metal alloys with the base metal during brazing movement of the alloy away from the fillet may cause erosion and reduce joint strength unsatisfactory surface condition or appearance excessive filler metal or rough surfaces may act as corrosion sites and stress concentrators also interfering with further testing. Brazing is a quick and inexpensive alternative to welding. Brazing is similar to soldering but at higher temperatures.

Brazing is also much easier then welding its a lot like using a glue gun. Quick and easy brazing aluminum copper and nonferrous metals. Brazed metal can also be stronger then.

Tools gear we use and recommend httpswwwamazon. Patching sheet metal holes using low temp solder. They have replaced sheet metal where it mattered a lot of it in fact and theyve been brazing pinholes where the structural strength of the panels wasnt compromised but had some small holes nevertheless or where the complexity of the panel fit would be cost prohibitive. Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.
