ERNiCrMo-3 is a nickel-chromium-molybdenum filler metal commonly associated with Alloy 625 (UNS N06625). It is used in specified gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) applications involving compatible nickel alloys, selected high-alloy stainless steels and certain dissimilar-metal joints. Alloy 625 filler metal is also used for some surfacing applications. The exact application must be checked against the applicable product standard and welding procedure.
What should be checked before selecting ERNiCrMo-3?
Start with the base-metal grades and the service conditions. The correct filler metal depends on the materials being joined, corrosion or temperature requirements, design code, welding process and approved WPS. For dissimilar joints, the welding engineer may also need to review dilution, deposited-metal chemistry and any post-weld treatment requirements.
Product form matters too. Buyers should confirm whether the job requires spool wire or straight lengths, along with the required diameter, classification, packaging and inspection documents. Do not select a filler metal only because its alloy name sounds similar to the base metal.
How can buyers verify the product?
Check that the product label, quotation, current datasheet and order-specific documentation identify the same classification. Confirm the standard edition and ask the supplier which batch and inspection records will accompany the shipment.
