99 COREWELD®
— Gas Shielded
Metal Cored Wires Coreweld
wires have metal powders in the core which gives them the high deposition rates
of flux cored wires
and the high efficiency of solid wires. The only slag produced by these wires
are small silicon islands
similar to those produced by solid wires. Argon-CO2
gas mixtures of 75% - 92% Argon/25% - 8% CO2
is the recommended shielding gas. Straight CO2
may be used for some wires. Coreweld
wires are now classified as composite wires and are covered by AWS Specifications
A5.18 for the carbon
or mild steel types and AWS Specification A5.28 for the low alloy types as shown
on the following
page.
