Large-Diameter Welded Elbow Size

Weld Elbow materials used for steel manufacturing steps with two longitudinal weld elbow is first on the steel sheet lofting, cutting two similar web-shaped, depending on the material is determined directly after the cold still need heating hot and then the sheet material into a mold by pressing the upper and lower mold clamping half weld elbow, that press-forming. Similarly, the other half as pressing method. Before the two halves of the blank group will press forming vertical welding, the need to each blank inside and outside the arc in the direction of the horizontal cut off more than expected, according to a welding process welding groove machining, welding group legislature finally formed.
