Sheet Metal Joining Without Fasteners

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.

Sheet metal joining without fasteners.

With this joining technique metal parts are deformed locally without the use of any consumables. Installation procedures devices and systems for joining sheets and profiles without fasteners. Self tapping is the use of self tapping screws to directly tap the thread on a piece of sheet metal so the fit is very good and can be disassembled. Screws on the other hand hold a joint together by griping a thread cut into the metal.

The clinching process is a method of joining sheet metal or extrusions by localized cold forming the materials. The result is an interlocking friction joint between two or more layers of material formed by a punch into a special die. By means of clinching joining technology steel and stainless steel materials as well as aluminium and other non ferrous materials are joined together without welding or fasteners. Clinching uses cold forming to assemble two or more layers of metal sheets.

Advantages of clinching joints additional fasteners are not required. A simple symmetrical clinchrivet is used as the joining element to produce a clinch connection without cutting the material. Sheet metal clinching joint creates a button type positive connection between two or three layers of sheet metal. Both need holes through the sheet metal but bolts use a nut on the backside to tighten the joint.

Welding is not an easy process and not everyone knows the proper way to do it. Painted or coated metal sheets can also be joined by this method without damaging the surface. Applications in the crash zone of passenger cars are best examples for the capabilities of this versatile joining method. Other than this nano metals and adhesives can also be used to join metal pieces together without welding.

It is possible to join metal pieces by methods like riveting soldering bolting or brazing. It creates an interlocking of two or more metal layers. The clinching process is a method of assembling sheet metal without welding or fasteners.
