Overview
Choosing the right filler metal is essential for creating a sound weld between two different metals and avoiding cracking or metallurgical incompatibilities. Rolled Alloys provides guidance through the weld wire selector and Metallurgical Services.
How It Works
A metallurgist or weld selection tool evaluates base metal chemistry, service temperature, dilution effects, and mechanical requirements to recommend the correct filler.
Steps:
- Identify both base metals and gather any known specifications.
- Contact Metallurgical Services to describe the joint and service conditions.
- Receive filler metal recommendations tailored to your application.
Helpful Tips
If the base metals have uncertain chemistry, metallurgists may suggest PMI (Positive Material Identification).
Dissimilar welds often require special techniques (controlled heat input, buttering layers, filler over‑alloying).
