First idea is to use CrMo2 consumables (or CrMo1 could be solution too, depending on application / requirements)

Preheat 200 degrC

PWHT at 690 °C , however

·         PWHT temperature is depending on strength requirements 4130 and required charpy values in weld metal

·         duration is depending on wall thickness and required charpy values in weld metal

 

Stick electrodes

·         OERLIKON CROMOCORD 2 STC

·         OERLIKON OE KV3 HR

TIG rod:

·         OERLKON CARBOROD CrMo2  or

·         OERLIKON CARBOROD KV3 (=B2)
