  • @Superduty: that weld passed the ASME 9 requirements of visual inspection, radiographic testing and bend testing. the guy is now working under Brunei Shell Projects in Brunei Darussalam

  • @Justwonderinghow: It depends on the approved WPS you are using. There are instances that the approved WPS indicates full SMAW Welding and others are Root - TIG, Hotpass -TIG and other Passes are SMAW. but normally, 3 inches diameter pipe and below and welded using TIG Welding.

    The advantage of TIG against SMAW is the the quality of the weld, however, TIG is more expensive than using SMAW

  • how much do pipe welders get paid?

  • @310extreme depends on the company to work in and race of the welder. American welders are highly paid. Asian welders are less paid.

  • It's interesting how he welded half the pipe and didn't even finish his only one welding rod. It is likely both halves of the pipe did not have a gap, and he was just melting the two edges and occasionally filling in with the rod when the keyhole became too large. I think I would have used at least 2-3+ rods because imo it's important to create a keyhole and use the filler rod. That would create the strongest root pass.
