The development history of straight seam welding pipe machines

I. The Nascent Stage (1880s-1920s)
In 1888, Germany invented the first resistance Welding Pipe Machine, which adopted the carbon electrode butt welding process and could produce galvanized water pipes with diameters ranging from 20 to 50mm. The typical characteristics of this stage include: the welding speed is less than 5m/min, relying on manual visual inspection of the weld quality, and it is mainly applied to gas pipelines and furniture frames.
Ii. Mechanization Upgrade (1930s-1970s)
During World War II, the surging demand for oil pipelines drove technological innovation: High-frequency induction welding technology: In 1952, the American Yoder Company achieved high-speed welding at 150m/min.
Breakthrough in forming technology: In 1965, Nakata Manufacturing in Japan developed the "roll forming method", controlling the wall thickness deviation within ±0.1mm.
Detection system: In 1973, ultrasonic flaw detectors were first integrated into the production line.
Iii. Digitalization and Intelligence (1980s- Present)
The three major technical indicators of modern straight seam welding pipe machines:
Laser weld seam tracking: In 1998, the LWM system developed by Siemens achieved deviation correction at the 0.02mm level
Flexible production system: In 2020, Baosteel built an intelligent production line capable of switching specifications within 15 minutes
Green manufacturing: In 2024, Hebei Hongrun Heavy Industry launched a photovoltaic-powered welded pipe production line
Iv. Future Outlook
According to the 2025 prediction of the "Welded Pipe" journal:
Vacuum electron beam welding technology in a space environment
② Remote operation and maintenance system based on digital twin
③ Hydrogen energy welded pipe integrated equipment will become mainstream
