Sheet metal joining techniques.

However an alternative way of adding open space is to take sheets or coils of metal and put it through an expanding machine. The last important method of sheet metal fabrication is fusing small panels together to produce larger complex parts. 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. In this screws bolts nuts studs and standoff.

Most of the time the rivets are fed and placed manually by hand. The riveting is carried out in the hole corresponding to the two parts and the rivet gun is used to pull. The most common type of metal fusion is welding. Screw joint is a type of temporary joint.

Expanding metal normally if you want to have open space in a metal object you d use a wire mesh or cut holes into a piece of sheet metal using a cnc punch laser. Techniques for joining sheet metal the ongoing push for thinner sheets is challenging engineers. Prior to riveting adjacent holes are punched.
