Season 2; Ep. 3 ASME Joint Reviews: How to Nail the Welding Demo (Hold Points, WPS, Gas, and Gotchas)
Episode Description
In this Pressure Beats podcast episode, the hosts explain why ASME pressure vessel work requires a joint review and focus on how to successfully execute the welding demonstration portion, which is harder to fix than documentation NCRs. They outline a “dog and pony show” method: gather the team, review the drawing/traveler and verify hold points are cleared and signed off, confirm the correct WPS, dial in machine settings on scrap while verifying volts/amps and gas flow, inspect bevels and tack welds, verify preheat, measure bevel and root gap to match drawing and WPS, and then weld while monitoring interpass requirements. They stress doing a dry run and highlight common pitfalls like uncertified orifice plates, uncalibrated gas mixer valves causing incorrect mixtures, and losing tungsten identification after grinding.
