Nickelarc A

AWS Specification : AWS A5.11 E NiCrFe-2

JIS Specification: NONE

Other Specification: NONE

 

I. APPLICATIONS:

Nickelarc A is excellent for overlaying nickel-chromium alloy on steel. More common applications include the welding of 5% and 9% nickel steel transport or storage tanks used for cryogenic products. The chemical or petrochemical industries use.

     Nickelarc  A for many applications such as valve seats and gates, coal gasification and wet process desulphurization equipment.

     II. DESCRIPTION:

Nickelarc A is a nickel-chromium-iron flux-coated electrode designed primarily for shielded metal arc welding of Incoloy® 800 to itself or to 9% nickel steels. This electrode is used for welding a variety of dissimilar wrought or cast forms of carbon steel, austenitic and ferritic stainless steel, and nickel-chromium Inconel® 600 to themselves or to each other. PHILARC Nickelarc A is frequently used for joining Incoloy® 800 to high nickel alloys 200 and 201 or to nickel-copper Monel® 400 and K-500.

     III. NOTES ON USAGE:

• Preheating is not necessary in general.

• Avoid the continuous welding if possible. It is effective to weld under 150ºC for reducing cracking tendency.

• Dry the electrodes at 150 ~ 200ºC for 30 ~ 60 minutes before use.
