To most manufacturers, spot welding is the most economical way to join two pieces of sheet metal. While joining sheet metal is the most common use for the process, resistance welding (RW) equipment actually can be used for a large variety of joining and heat-treating projects, some of which are not so well-known.
What Is Pot Metal, and How Do You Weld It?
Since it was melted in a pot, it was informally referred to as pot metal. In a nutshell, pot metal is a colloquial term referring to alloys consisting of inexpensive, low-melting-point metals. For starters, an alloy is any metal made by combining two or more metallic elements to have a stronger or corrosion-resistant metal.sp.info What is Galvanized Steel?
