... in which each pass results in warpage. Unless the setup compensates for distortion or a constraint is applied, multi-pass welds will pull a weldment out of alignment. Considerable care must be used in the set-up and in the sequence of welding. Stress-relief heat treatments after a number of weld passes...

... On a fine scale, microstructural gradients exist within the heat-affected zone due to different time-temperature cycles experienced by each element of material. Gradients on a similar scale exist within solidified multi-pass weld metal due to bead-to-bead variations in thermal experience. Compositional...

.... If weldments in stabilized grades are then heated into the sensitizing temperature range of 425 to 815 °C (800 to 1500 °F), for example, during stress-relieving treatments, high-temperature service, or subsequent weld passes, chromium carbide can precipitate. The precipitation of chromium carbide leaves...

... weldment. These include poor workmanship, a variety of hydrogen-assisted cracking failures, stress-corrosion cracking, fatigue, and solidification cracking in steel welds. Hydrogen-assisted cracking can appear in four common forms, namely underbead or delayed cracking, weld metal fisheyes, ferrite vein...
