Welding A106-B To A335-P22

For welding A106-B to A335-P22, a filler metal like E8018-B2 is recommended. This electrode is suitable for similar Cr-Mo alloyed steels and is often used in steam plant, boiler plant, and pipe production applications. Alternatively, filler wires like ER80S-B2 or ER90S-B3 can be used for TIG or MIG welding. 

Elaboration:

E8018-B2:

This is a basic shielded metal arc welding (SMAW) electrode designed for welding Cr-Mo alloyed steels. It's known for producing a weld deposit with similar properties to the base metal, making it suitable for applications where strength and ductility are crucial. 

ER80S-B2 and ER90S-B3:

These are filler wires used for gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW). They offer good weld properties and are compatible with A335 P22 material. 

A106-B and A335-P22:

These are both steel grades commonly used in piping and pressure vessel applications. A106-B is a carbon steel, while A335-P22 is a low-alloy steel. The welding process must consider the differences in their properties and ensure a strong, durable weld.
