Is it possible to weld repair forged nozzles?

It depends on the nature of the repair, but in general, yes.

What is the specific repair that you wish to make?

 

[puigi]

If the part is made IAW standard material specification ASTM/ASME A-192A - A-192M, consult the document. The requirements for repairs by welding are listed in section 13.

There is unfilled material in the forging on the barrel side. I want to know weld repair is possible and do I need to PWHT after repair?

 

[fegenbush]

The PWHT requirements are based on the material type. If it is SA-105 material, grind, weld, and blend as necessary and call it a day. If the repair is documented, there shouldn't be any cause for concern.

 

[puigi]

SA-105 is a material specification for forgings in piping applications.
The material specification I listed in my earlier post was incorrect. The correct material specification is A-182A -A-182M (SPECIFICATION FOR FORGED OR ROLLED ALLOY AND STAINLESS STEEL PIPE FLANGES, FORGED FITTINGS, AND VALVES AND PARTS FOR HIGH TEMPERATURE SERVICE)
Whether or not PWHT is required will be determined by the material and nature of the defect.

Is it possible to weld repair forged nozzles?

Yes. Weld repair requirements will be governed by code of construction or other specification.
