Gross B, Connelly T, van Dijk H and … NettetIf you are a pipeline engineer, you must be familiar with the term girth welding.Yes, you are right. Line pipes used in the pipeline industry are generally joined together using girth welding.In this article, we will explore more about the girth welding process. So, let’s start with the definition of girth welding.

NettetGirth welds were prepared from a single length of 1067 mm O.D., 12 mm W.T., Gr. 483 pipe to CSA Standard Z245.2. Laboratory-scale test coupons were prepared from a … NettetWeld inspection probes offer a low-profile housing and front-exit cable to avoid interference with the scanner probe holder. These probes are suitable for manual and automated inspections of thick welds in addition to inspection of castings, forgings, pipes, tubes, and machined and structural components for cracks and welding defects.
NettetAutomated ultrasonic testing (AUT) with phased array zone discrimination is a common method used to inspect pipeline girth welds. AUT enables the accurate sizing of … NettetThe weld that joins pipe segments together is also made of the CRA material. Challenges of CRA weld inspection When inspecting a weld with phased array pulse-echo or pitch-catch standard configurations, …
