Jul 17, 2011 Having said that, the lack of PWHT is why you have experienced SCC. A proper repair would require PWHT of the seam welds to prevent additional cracking. Faced with a similar situation, we would consider either a temper bead welding repair or PWHT of the weld seam after repair.

GENERAL WELDING RECOMMENTADIONS

General Welding Recommentadions

Any defects or pronounced undercut along the toes of the welds must be corrected by grinding or repair welding before the peening process. During peening, the temperature of the work piece must be below 200 C 400 F. The peening tool shall be held firmly against the toe of the weld such that the edge of the bit lies along the toe of the weld.

Sep 06, 2011 Using 309 for the initial weld layers and go to 410 Ni-Mo would not be wise. What I would do is use a low preheat of 250 deg F. This is not that difficult to do with several rosebud torches. Use 410 Ni-Mo and with stringer beads with sufficient overlap use the temper bead approach and allow the weld region to cool to below 212 deg F.
