Below is a list of Welding Alloys manufacturers from Huntington Station, New York. Welding alloys are metals that are formed from two or more metallic elements that are utilized during the welding process in order to function as a filler metal. The welding process involves the bonding of two separate pieces of metal together by means of melting the points desired to be joined in addition to the filler metal (which is the welding alloy) and afterward allowing the metal to cool and thus cement the bond.
