CHF43/CHW-S1
Flux/Wire Combination for Submerged Arc Welding
AWS F6A0-EL12
GB F4A2-H08A
Description: CHF43/CHW-S1 flux/wire
combination has very nice performance in welding, arc is stabile; weld metal
shows a fine appearance, and slag detachability is easy. Both AC and DC can
be applied, when using DC the wire should be contacted straight polarity. It
is suitable for welding of 450MPa grade strength steel structures, e.g. LPG
cylinder as well as ship structures as same strength. Before welding the
work pieces must clear away impurities and the flux must be baked in
temperature of 200℃-250℃ for 1-1.5hours.
