Rondo Weld - Erw, Saw Welds (Paut, Emat)

Product Code :
Category : Online / Inline Systems

RONDO WELD is an advanced automated inspection system combining PAUT (Phased Array Ultrasonic Testing) and EMAT technologies for high-precision inspection of thick weld seams. It ensures reliable, high-speed weld inspection for pipe and tube manufacturing lines.

The RONDO WELD system automatically tracks the longitudinal weld seam on pipes and performs detailed inspection using advanced ultrasonic methods. With its gantry-based PAUT structure and non-contact EMAT capability, it provides flexible solutions for both offline and inline applications.

Technical Details
