AWS A5.11 ENiCrFe-7
Nickel Base Alloy, Coated Electrode — INCONEL® Welding Electrode 152
INCONEL® Welding Electrode 152
INCONEL® Welding Electrode 152 is used for shielded-metal-arc welding of INCONEL® alloy 690. It has a higher chromium content which improves resistance to stress-corrosion cracking in the nuclear, pure water environment. It was designed to produce high quality welds in all positions. This electrode also produces corrosion-resistant overlays on most low-alloy and stainless steels. Other uses include applications requiring INCONEL® alloy 690 “glass melters” used for the disposal of nuclear waste. It is also useful for dissimilar joints involving INCONEL® and INCOLOY® alloys, and stainless, low alloy and carbon steels.
The electrodes provide excellent operability for groove and fillet welding in the downhand position and the smaller diameter electrodes are also suitable for all position welding. Power supply: direct current, electrode positive.

INCONEL® Welding Electrode 152M
INCONEL® Welding Electrode 152M is used for the shielded-metal-arc welding of INCONEL alloy 690, and the overlaying of carbon steels and stainless steels to provide a nickel-chromium alloy corrosion resistant surface. The high chromium level provides excellent resistance to stress corrosion cracking in the nuclear, pure water environment. The product can also be used in applications requiring resistance to oxidizing acids. It is useful for dissimilar joints involving INCONEL and INCOLOY alloys. This product contains Boron and Ziriconium to minmize the tendency for ductility-dip cracking.
