Released mid-2021, this standard harmonized acceptance levels across VT, PT, MT, UT, and RT. The key update was the alignment of UT acceptance criteria with RT (making PAUT a true substitute).
Welding inspection is critical for ensuring structural integrity in the oil and gas, aerospace, construction, and automotive industries. Historically, this field relied heavily on the subjective interpretation of human inspectors. However, literature from 2020 and 2021 reveals a paradigm shift. The convergence of high-speed computing, advanced sensors, and machine learning (ML) propelled the sector toward "NDT 4.0"—a concept heavily cited in papers from this era, focusing on digitization and data connectivity. welding inspection technology 2020 pdf 2021

Visual inspection criteria for weld profiles (reinforcement, undercut, porosity) have not changed since 2020. The PDFs from that era provide the same useful templates and acceptance/rejection criteria as today’s standards. Prior to 2020, welding inspection relied heavily on:
