6、s wire has been used typically as filler metal for gas-metal-arc or gas-tungsten-arc welding of critical weldments of low-alloy steels requiring a weld joint capable of being heat treated to a strength approximating that of the parent metal, but usage is not limited to such applications.1.3 Classifi
7、cationWire supplied to this specification is classified as follows:Type 1 - BareType 2 - Copper Coated1.3.1 Type 1 shall be supplied unless Type 2 is specified.2.
