Stainless steel welding electrode E316L-16 (A022) |
|
APPLICATION | It is suitable for welding low carbon 00cr18ni9 stainless steel structure, also can be used to the corrosion resistance of stainless steel structure,such as the 0cr19ni11ti, whose working temperature below 300 ºC, it is mainly used for manufacture of synthetic fiber, fertilizer, oil and other equipment. |
WELDING POSITIONS: | PA, PB, PC, PD, PE, PF |
FEATURES: | Both AC and DC can be used and can be all-position welding. It can reach excellent welding performance, stable arc, little spatter, easy slag removal and good weld appearance. The deposited metal has good resistance to intergranular corrosion. |
Attention: | |||||
1. The electrode must be re-dry by 320ºC-350ºC for 1 hour before welding. | |||||
2. The rust, oil, water and other impurities of the weld area must be removed before welding. | |||||
3. DC+ is better than AC, lower heat input is suggested, the temperature of preheat and interpass keep under 150ºC. | |||||
