Sheet metal joining techniques.

Screw joint in sheet metal. Folding and adding bending tabs is one of the easiest and most economical way of making moderately strong joints in sheet metal parts that will permanently or semi permanently attach to one. But it should be remembered that it is a temporary joint. Brazing is a method of joining metals by the use of a fusible alloy consisting largely of brass and melting at a temperature above 600 c.

Joining methods there are many different joining methods for fixing metal in place. Riveting is a type of permanent joining operation. Non permanent methods include nuts and bolts screws and rivets. Most of the time the rivets are fed and placed manually by hand.

Appliance engineers have several options for joining sheet metal including screws rivets welding bonding clinching and folding. The most common type of metal fusion is welding. In this screws bolts nuts studs and standoff. Brazing produces a much stronger joint than soft soldering but requires greater heat from oxy acetylene flame.

The two pieces of sheet metal connected to each other by folding or bending tabs in the form of a. Appliance manufacturers are under constant pressure to control their material costs. Prior to riveting adjacent holes are punched. 6 types of sheet metal joining techniques folding tab joints.

Most engineers rely heavily on mechanical fasteners. Photo courtesy general electric the appliance industry is eager to use thinner sheets of steel. Techniques for joining sheet metal the ongoing push for thinner sheets is challenging engineers. The riveting is carried out in the hole corresponding to the two parts and the rivet gun is used to pull.

The last important method of sheet metal fabrication is fusing small panels together to produce larger complex parts. Whilst many would consider a rivet a permanent. Riveting is one of the oldest joining techniques to join two sheets of metal a hole was drilled or punched through and then the solid rivets with a head on one side and a cylindrical shaft were put in. After placing the tail was deformed and a thight connection was created.

Screw joint is a type of temporary joint. However an alternative way of adding open space is to take sheets or coils of metal and put it through an expanding machine. How to join sheet metal parts.
