J506WCu
Description:
J506RH is a low hydrogen potassium type of high toughness ultra-low hydrogen and low alloy steel electrode, AC and DC. Has a good welding process, arc stability, easy slag, deposited metal has excellent ductility, toughness and crack resistance. All-position welding.
use:
Applicable to E36, DE36, A537 and other low alloy steel important structural welding. Such as offshore platforms, ships, pressure vessels and so on.

Precautions:
1. Welding before the electrode to be 350-400 ℃ baking 1h, and then placed in a 100-150 ℃ incubator, with the baking with the use.
2. Welder before welding to be cleared of rust, oil, water and other impurities.
3. When welding to be used to operate a short arc to narrow the weld is appropriate.
