English to Arabic Tech/Engineering Electronics / Elect Eng Welding Electrodes Specif

flux/wire combination has good performance in welding. 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 suitable to weld 450MPa - 500MPa tensile strength structures, such as boilers, ships, bridges, pressure vessels, as well as LPG cylinders. Before welding, the base metal must clear away impurities and the flux must be baked in a temperature of 300°C - 350°C for 1-2 hours.
