Internal welding: vertical multi-wire submerged welding (up to four wires) is adopted to weld the inside of straight seam steel pipe;7. External welding: vertical multi-wire submerged arc welding is adopted to conduct welding on the outside of straight seam submerged arc welding steel pipe;Straight steel tube spot located at SAW liaocheng 8. Ultrasonic inspection Ⅰ: inside and outside of straight seam welded steel pipe weld and weld on both sides of the base of 100% of the check;9. X-ray Ⅰ: 100% of inside and outside weld X-ray industrial TV inspection, using image processing system to ensure the sensitivity of detection;This expectation is confirmed by the manufacturing production and operation activity expectation index in February, which is 61.8% in that month, up significantly by 10.5 percentage points compared with the previous month, and the production and operation activity expectation index of large, medium and small enterprises is above the critical point of 50%.
