2. Abstract:
Pipes are cut to a predetermined length by an automatic plasma arc cutting device. After accomplishment of inside and outside welding, while on the production machine full length of pipe is examined by automatic ultrasonic unit with the help of 8 probes, 4 for checking plate defects and 4 for checking welding defects. Flux and slag from inside the pipes is cleaned. Pipes are inspected for any visual defects. Fluoroscopic inspection of pipes presents the entire spiral seam on visual display for analysis of all the ultrasonic indications for defects, if any, in the weld seam.
