Product Details


spiral welded pipe sizes The arc diffusion Angle of semi-automatic FCAW downward welding is large, resulting in large radial energy gradient of arc voltage, decreasing amplitude, gentle distribution and shallow penetration. Therefore, it is not suitable for deep penetration welding.However, its weld forming coefficient is large, splash rate is low, smooth smooth weld, suitable for pipeline downward welding process.

Spiral Welded Pipe Sizes2The arc diffusion Angle of semi-automatic FCAW downward welding is large, resulting in large radial energy gradient of arc voltage, decreasing amplitude, gentle distribution and shallow penetration. Therefore, it is not suitable for deep penetration welding.However, its weld forming coefficient is large, splash rate is low, smooth smooth weld, suitable for pipeline downward welding process.


In the process of semi-automatic FCAW downward welding, 7 main process parameters are the most concerned problems in welding.These 7 process parameters are arc voltage, current, wire feeding speed, wire Angle, welding speed, thrust current and wire dry extension length.The advantages of small spatter, good weld molding and high production efficiency can be realized only when the seven process parameters are completely matched.
