Description:
CHE56 is a low hydrogen
potassium type welding rod. The deposited metal shows a satisfactory
plasticity, impact toughness and crack resistance. It is widely for
fabricating structures made of 550MPa tensile strength mild steels and low
alloy steels, such as ships, boilers, high press vessels, bridges,
sky-scrapers, and so on. The groove of base metal should be cleared
impurities away and the rod must be baked at a temperature to 350℃ then be
held 1-2 hours before welding.
