The importance of edging the closed iron drum

- Apr 18, 2020-

The closed iron drum will be flanged, corrugated, bulged and crimped after the welding of the drum body is completed. For barrels that are welded without edging, the thickness of the weld is twice the normal thickness. The uneven thickness of the barrel body affects the quality of the subsequent process, especially when crimping and sealing. A large amount of pimples accumulating on the weld seam can not meet the requirements of normal curling. This area is called the crimped weld triangle area, which is a troublesome area. Because there are more materials than other curling parts, it is difficult to adapt the groove shape of the curling roller, so that iron tongues often appear, and gaps appear on both sides of the seam weld, resulting in leakage in the triangular area. This is the most serious problem with the quality of iron drums.

This is the most serious problem with the quality of iron drums. Therefore, in order to make the weld seam have a thickness similar to other parts, edging is the most direct method, because the edge of the weld seam is edging through the edge, the thickness is thinner than other parts, when the seam is welded , It will significantly reduce the thickness of the weld. Therefore, in order to make the welded seam have a thickness similar to other parts, edging is the most direct method, because the edge of the welded seam is thinner than other parts by edging, when the seam is welded After that, the thickness of the weld is significantly reduced.
