1. Preheat joint area(other area, cover with mineral wool). 2. ENiCi or ENiFe-CI. 3. stringer bead. 4. peening is to be done on weldmetal immediately after deposition of every electrode. 5. Cover with mineral wool after completion of complete weld for slow cooling.

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 !

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.

308 L is for better corrosion resistance application,  But 308 H is for high temperature with minimum carbon control is maintained say 0.04, inferior to corrosion resistance.
