In order to strengthen the quality control of large-scale segment welding and strengthen the welding and closing ability of large-scale segments, Dalian Shipping actively conducted market research. After many arguments, it introduced “SG-2Z gas-electric vertical weldingâ€.
In recent years, with the acceleration of the pace of entering the offshore manufacturing industry, Dalian Marine has undertaken more and more offshore manufacturing projects, and the large-scale segmented welding and closing projects have also increased. Large-sized segmented welding is closed, with high quality requirements and time consuming. The strength of welding ability directly affects the level of closing efficiency.
A treaty 20 m weld usually requires three sets of two oxygen welders to work simultaneously for 24 hours, and the use of "SG-2Z type gas electric vertical welding" can be completed in just 2 hours, and the quality is much higher than artificial Welding, the power consumption is only one-third of the manual welding, in comparison, higher efficiency, better quality and lower energy consumption.
