Welding pot metal

 

Pot metal is nothing more than a term that is used to refer to alloys that consist of inexpensive, low melting point metals used to make fast, inexpensive castings. Welding pot metal is certainly not one of my personal favorites.  There is no real scientific metallurgical standard for pot metal; some common metals that are included in pot metal include lead, zinc, tin, copper, magnesium, iron, aluminum, and cadmium. The primary advantage of pot metal is that it is quick and easy to cast. Due to its low melting temperature no sophisticated foundry equipment is needed and specialized molds are not necessary either. It is sometimes used to experiment with molds and ideas before using metals of higher quality.  Welding pot metal tutorials are available in many places online for your viewing.
