Hello all,

I have a case for a U stamp vessel , Vessel designed initially with no PWHT, hence non PWHT wps applied throughout the production phase, later the manufacturer converted vessel requirement to PWHT ! Manufacturer justifies since all other patemerts met the requirement othethan PWHT , they intent to proceed for PWHT ! What’s ASME position shall be here ?

Regards

Vasagan

When all other essential variables are same , except PWHT , you have to revise WPS with PWHT and do further needful in consultation with AI

Thanks

Thanks Vishwa , but how we prove mechanical strength on the welded joints for the heat treatment ?

Dear expert,

We need to weld UNS 32906 material...please suggest which electrode is suitable.

Hi,

Use E2594-15 and E2594-16 under SFA 5.4

The E2594-15 and E2594-16 electrodes are classified under the SFA 5.4 specification for stainless steel covered electrodes used in Shielded Metal Arc Welding (SMAW). These electrodes are specifically designed for welding super duplex stainless steels, including UNS S32906, S32750, and S32760.

The deposited weld metal from both electrodes must meet the following composition as per AWS A5.4/SFA 5.4

Selection Guide:

Use E2594-15 for critical and high-strength applications requiring low hydrogen welds.

Use E2594-16 for general applications and easier weldability in all positions.

Regards,

Deerendra
