AI Overview
Welding inspection on a tube mill line involves continuous, in-line monitoring of the weld seam, typically using Eddy Current (ET) for defect detection and Ultrasonic Testing (UT) for weld integrity. Key techniques include inspecting for surface defects, bead profile, and weld tracking to detect flaws like lack of fusion or porosity, often supplemented by destructively testing samples via flattening, flaring, or flattening tests.
