MIG brazing is a welding process that has been around for years and the process is gaining popularity recently by professionals and hobbyists alike due to the benefits it can offer, especially with silicon bronze filler metal. Traditionally, brazing processes have used an oxy-fuel acetylene torch to melt the filler metal, but in MIG brazing, a standard MIG gun is used to run brazing wire. Brazing filler metal melts at 840 degrees Fahrenheit, which is lower than the melting point of the base metals being joined. Due to the lower melting point the filler metal provides capillary action – fluid being drawn into the weld joint – when brazed. When braze welding with silicon bronze filler metal, the molten metal bonds the base materials together, but does not provide fusion like mild steel filler metal. Because of this, silicon bronze can be used for welding dissimilar materials together, such as cast iron to steel, stainless steel to steel, etc. The low melting point of silicon bronze also provides a cooler welding process, putting less heat into the material that is being welded. Reduction in heat input leads to less distortion and the ability to weld on heat sensitive materials without compromising the physical properties. It is an ideal process for joining thinner metals together, filling gaps, and sheet metal work such as HVAC and auto body welding. When done correctly, a silicon bronze weld will have a gold colored finish that provides contrast to the base metal. Gold colored welds are often used for aesthetic appeal in metal art applications.
