Steel Strip Width Measurement and Deviation Warning for Spiral Welded Pipe: Grating Ruler + Siemens PLC300 Implementation

Harris Lee explains how a three-station grating-ruler measurement system integrated with a Siemens PLC300, MCGS HMI, and 4G cloud access solves the strip deviation, off-milling, uplift, and distortion problems that undermine forming quality in spiral submerged arc welded pipe production — and why controlling working strip width to within 1 mm matters for downstream weld integrity.
