Re: [MW:13395] why should finish welding in single cycle

One of the probable reason is to have sufficient weld metal to resist contractual Residual stresses to prevent cracking. Inaddition to this there are other reasons also depending on materials like Chrome-moly steels to maintain sufficient preheat and interpass, to avoid dehydrogenation treatment in between during stoppage.
