AWS A5.5 / ASME SFA5.5 E9018-M
EN 757 - E50 4 B 4 2
Notes on Usage
Welding Positions:
① Dry the electrodes at 350~400℃(662~752℉) for 60 minutes before use.
② Adopt back step method or strike the arc on a small plate prepared for this particular purpose because arc striking on base metal is in danger of initiating cracking.
③ Preheat at 80~100℃(172~212℉). The temperature to be applied varies in accordance with plate thickness and kind of steel.
Applications
AWS A5.5 / ASME SFA5.5 E9018-M can be used for welding of high tensile weather proof steel used in pressure vessels, bridges, rolling stocks, machines.
Welding Position
Characteristics on Usage
AWS A5.5 / ASME SFA5.5 E9018-M is an iron powder low hydrogen type electrode which provides good workability in all positions.
The weld metal has a good crack resistibility because of less hydrogen contents.X-ray performance and usability are good.
