Type of product
LH J506
Equivalent to AWS E7016
Description:
Aws E7016 is carbon steel electrode with low hydrogen potassium coating, high welding efficiency, beautiful shaping in welding joint and small splashing. It is easy for arc striking and deslagging, and available for welding at all positions. The deposited metal has good plasticity, low-temperature toughness and resistance to cracking.
Purpose: For welding of important carbon steel and low alloy steel, such as welding of 16Mn and welding of steel with A,B,D,E class applied in vessel.
Precautions:
1. Electrodes must be baked at 350℃ for 1 hour before welding.
2. Impurity such as rust, oil and water must be removed from the welded parts before welding.
3. Short-arc operation and narrow-gap welding shall be adopted.
