Hi Expert Root Pass, hot and Fill 1 pass, we use ERNiCrMo-3 which 625 filler wire , Welding Process GTAW. Remaining fill pass use SAW Process with 625 filler metal,

Hi Expert, Is there anybody can explain Longitudinal Crack observed on SAW Process with ERNiCrMo-3 ? Is it because hot cracking by austenitic weldment, weld shape (Weld/Depth),segregation or flux ? In this case I want to joint pipe to pipe (X65) with Clad 625 inside, there is no option , we...

@metengr Thank you so much, i miss that clause anyway. @DOn56 Yes, you're right. but we want to qualified welding operator, which the machine only designated to perform fillet weld as well. I want to reduce cost of laboratory with using RT in house. Thank you very much for the response...

Hi Expert Regarding Fillet Weld Performance Qualification Is it possible if we perform Fillet Performance Qualification (Welding Operator Test) with Volumetric NDE (RT / UT) Instead of Mechanical Testing ( Macro + Fracture Test ) ? We have different interpretation , As per QW 302 Volumetric...

Hi Expert, I have some question regarding Flux Type of SAW with 625 filler metal , Is there anybody here which have some experience about SAW with 625 filler metal ? Is there any concern about solidification crack with the flux of SAW 625 or there is another concern ? is there any brand which...

Hi Expert, I have some issue regarding weld overlay using ER2209 (Duplex) Is it possible to weld overlay ER2209 direct to carbon steel (1st Layer and 2nd layer with ER2209) instead of using buffer layer ER309L (1st Layer ER309L + 2nd Layer ER2209) , Is there any Corrosion problem as per G48...

Thanks all for great response , Previously, I have some experience with depositing carbon steel filler above 625 weld deposit, I got solidification crack (longitudinal crack along the weld deposit) as i saw it , it's very brittle phase. Some people say it caused by NiS inclusion form which...

Hi Expert, I Have some question regarding Clad Pipe 625, Is it possible to use 625 Filler wire (ERNiCrMo-3) on the Root and Hot Pass only , then Carbon steel Wire (i.e. ER70S-6) for the subsequent welding (Fill and Cap) ?,I there any problem with dilution? (Metallurgical perspective) we're...
