Description:
CHE56
is a welding
electrode covered with potassium type coating. The deposited metal shows a
satisfactory plasticity, impact toughness and crack resistance. It is widely
for fabricating structures made of 500MPa grade high tensile steels and low
alloy steels, such as ships, boilers, high press vessels, bridges,
sky-scrapers, etc. The groove of base metal should be cleared away
impurities and the electrode must be baked at a temperature to 350℃
then be held 1-2 hours before welding.
