CHF101/CHW-S9
Flux/Wire Combination for Submerged Arc Welding
AWS A5.23 F8A0-EA4-A4
Description: CHF101/CHW-S9flux/wire
combination has excellence welding performance. The weld metal shows a fine
appearance and the deposited metal has a satisfactory low temperature
toughness and high crack resistance. Both AC and DC can be applied, when DC,
the wire should be contacted straight polarity. It is used to weld
550-700MPa important high strength steel structures, such as cranes, heavy
trucks & engineering machinery,bridges and high pressue vessels, etc. It
could be four wires welding at same time and the welding speed is
1.70m-2.00m per minute. Before welding, the base metal must clear away
impurities and the flux must be baked in a temperature of 300℃-350℃ for 1-2 hours.
