Different Types Of Sheet Metal Joints That May Be Used To Join Sheet Metal

Edge joints tend to be a weaker type of welding joint so they are more commonly used in sheet metal.

Different types of sheet metal joints that may be used to join sheet metal.

2 57 is one of the most widely used methods for joining light and medium gauge sheet metal. Sheet metal joints there are really only five ways in which the edges of sheet and plate metals can be fastened together viz by soldered brazed welded grooved and riveted joints. These methods of joining sheet metal both entail deformation. The first type of welding may be of similar metals.

And the second type may be of similar or dissimilar metals to be welded with the third additional metal or alloy which has got low melting temperature than the metal to be welded. It consists of two folded edges that are locked together with a hand groover fig. Hemming is done along an edge or seam and involves folding one metal sheet over the second. Mainly two groups of welding are used in industry.

Screw joint in sheet metal. The grooved seam joint fig. Two pieces of metal are held with their edges parallel and a seam is made along this joint. But whilst we are limited to the use of one or other of these forms of jointing there are numerous modifications of them in practice.

In this screws bolts nuts studs and standoff are used to join two and more metal parts. Screw joint is a type of temporary joint. This assembly method is relatively simple and convenient and can complete rapid assembly. See more ideas about sheet metal metal metal bending.

Folding tab joints. A clinch joint is made with a punch at a single location and looks a little like a riveted joint. When making a grooved seam on a cylinder you fit the piece over a stake and lock it with the hand groover fig. The two pieces of sheet metal connected to each other by folding or bending tabs in the form of a buckle and a clamping slot.

If an edge joint is required for bigger or more weight bearing construction it can be strengthened using filler metal.
