While traditional methods like Magnetic Particle Testing (MT) and Liquid Penetrant Testing (PT) remained industry staples for surface defect detection, 2020 and 2021 saw a massive surge in advanced volumetric NDT technologies. Phased Array Ultrasonic Testing (PAUT)
Another 2021 work proposed an automated system for applying to perform post-weld treatment and quality inspection of linear welds. The system reduced overall treatment variance, improving process stability while minimizing human involvement. welding inspection technology 2020 pdf 2021
