Seaming Operation In Sheet Metal

Hemming is the process in which the edge is rolled flush to itself while a seam joins the edges of two materials.

Seaming operation in sheet metal.

A variety of seams are used to connect pieces of sheet metal in construction auto body creation and fine art sculpture. The hollow tube can be seamed or welded for joining. With seaming the edge of sheet metal is folded but it doesn t sit flush. Seams are commonly used in the food industry on canned goods on amusement park cars in metal roofing and in the automotive industry.

Seaming is a sheet metal joining process. The type of seam used depends largely on the application. This sheet metal seamer can work with 20 gauge steel without any hassle at all. The seamer will grip the metal evenly the alignment marks on both sides of the clamper surface help a lot.

In car part production hemming is used in assembly as a secondary operation after deep drawing trimming and flanging operations to join two sheet metal parts outer and inner together. Hemming and seaming are two similar metalworking processes in which a sheet metal edge is rolled over onto itself. It is perfect to work within hvar systems for metal folding tasks. Seaming involves bending the edges of two parts over on each other.

Round tubes for example can be bent from sheet metal using a multiple action machine. Hems are commonly used to reinforce an edge hide burrs and rough edges and improve appearance. Normally hemming operations are used to connect parts together to improve the appearance of a part and to reinforce part edges. Some sheet metal bending operations involve the use of more than 2 die.

Some seams are created entirely by machine or in a metal shop while others are made to snap together without requiring welding or soldering on site. With hemming the edge of sheet metal is folded so that it becomes flush with the area onto which it s rolled.
