HSMH AWS A5.1 E7018,2.5mm-5.0mm e7018

Specifications

1 stable arc,lower spatter,little smoke
2 excellent welding performance
3 higher deposition efficiency
4 easy to restrike

Description::E7018 is iron powder low potassium hydrogen coating of carbon electrode. Ac/dc, for all position welding. Its characteristic is covering contain iron powder, can reduce welding layer, improve the deposition efficiency. Arc stability, fly sword is small, easy to take off the slag, the welding process good performance.

Application:Suitable for welding of carbon steel and low alloy steel welding.
