1. Product details: 1). Adopts dc reverse connect 2).Little splash off slag easy 3).Low-alloy moulding beauty good toughness
2. Abstract: Low-alloy electrodes is an outstanding quality all position welding electrode with extra low hydrogen potassium type coating for high tensile strength mild steel and low alloy steels. Its nominal welding efficiency is about 110% due to iron powder is contained. The weld metal shows an excellent low temperature toughness and high crack-resistance. It is widely used in important projects of ship, boilers, high pressure vessels, bridges, skyscrapers, offshore drilling platforms, nuclear power plants and so on. The groove of base metal should be cleared impurities away and the electrode must be bake at a temperature to 400°C then be held 1-2 hours before welding, 2.5mm or less one should be done by 350°C then be held 1 hour.
3. Feature: 1) Welding temperature is lower than 300 degrees 2) Chemical composition of deposited metal: C<=0.12 Mn<=1.25 Si<=0.6 S<=0.035 P<=0.035 Cr - Cu - Ni - 3) Heat-resistant-Steel-Electrode
4. Application: It is mainly used for welding the structures on low-alloy steels with high strength such asσb 980Mpa. |
