Hunan Xunzhuo Import & Export Co., Ltd.
It is suitable for the welding of carbon steel and low alloy steel structure, such as Gr.50, and so on.
Characteristics:
E7018 is basic potassium type electrode with low hydrogen. Both AC & DC can be used and can be weld for all-position. It have excellent welding performance as good arc stiffness, little spatter, easy slag removal etc., and perfect mechanical properties of deposited metal.
Attention:
1. The electrode must be re-dry by 350ºC-380ºC for 1 hour before welding. 2. The rust, oil, water and other impurities of the weld area must be removed before welding.
