Product Details


spiral welded pipe Compared with the downward welding process under the protection of semi-automatic CO2 gas, the downward welding process of semi-automatic FCAW has the advantages of excellent process performance, stable arc, high production efficiency, small splash, beautiful weld molding, good adaptability of steel type and spatial position, strong wind resistance and so on.Compared with the traditional downward electrode arc welding process, it increases the primary pass rate of hot welding, filling welding and cover welding to about 10% on average

Compared with the downward welding process under the protection of semi-automatic CO2 gas, the downward welding process of semi-automatic FCAW has the advantages of excellent process performance, stable arc, high production efficiency, small splash, beautiful weld molding, good adaptability of steel type and spatial position, strong wind resistance and so on.Compared with the traditional downward electrode arc welding process, it increases the primary pass rate of hot welding, filling welding and cover welding to about 10% on average, and increases the productivity by 1.25 to 1.About 5 times.Compared with automatic welding, it has the advantages of less equipment investment, fast cost recovery and low comprehensive cost.Welder training time is short and easy to master.In more than ten years of engineering construction, the quality of welding is stable. After X-ray inspection, the average pass rate of welding joint is about 95% to 98%.The use of semi-automatic FCAW downward welding process in pipeline construction has reached the "four high" standard proposed by the project owners at home and abroad, which is completely suitable for all kinds of pipe diameter pipeline downward welding process requirements.So, get owner, inspect inspect, the favour of construction unit.
