A. Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool causing fusion. Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.

Below are short introductions to some of the welding processes.

1. Soldering

Soldering is suitable for light duty joining of sheets, tubes, electrical and electrical connections. It is an understated but widely used process through the sheet metal industry most commonly used to join brass and copper and light fabrications where welding would introduce too much heat.

2. Brazing

Brazing is a joining process which is similar to soldering but uses filler material that has a significantly higher melting point ( 450 to 800o ). Copper, Nickel, Silver are the most frequently-used base metals for brazing alloys. The process is used widely for joining and sealing on higher performance applications such as copper based alloys e.g. pipe fabrications, heat exchangers and vessels. It is also used to join brass when soldering and TIG welding is not suitable.
