Verify Before Welding

Verify the stainless grade and carbon-steel grade before choosing 309-family filler.

Check service temperature, corrosion exposure, dilution, and procedure requirements.

Dissimilar-metal work may require engineering or WPS review.

Use note: AWS classifications are used here as practical lookup keys. Always verify the current AWS specification, manufacturer data sheet, WPS, code requirements, base metal grade, shielding gas or current type, diameter, and package size before purchasing or welding.
