TACKING – WELDING – CLINCHING
Sheet metal parts can be assembled through different processes, depending on the purpose of their final utilization.
In particular, assembly can be performed by:
TACKING
- CONVENTIONAL TACKING (also called electrical tack-welding) or PROJECTION TACK-WELDING
which consists of the melting of 2 components as a result of the electric discharge of two copper electrodes, which allows permanently joining solid parts to one another

WELDING
- WELDING is the process through which a localized application of heat allows melting two metals together, thus permanently joining them.
Welding can be performed through various methods.
The most popular ones, which also Elifra utilizes in its process, are:
– TIG welding, suitable when welding parts that need pressure-tightness
– MIG-MAG welding, suitable when welding parts that need mechanical tightness

CLINCHING
- CLINCHING, which is usually called cold welding, is a process used to join metals through the local cold deformation of the materials. It is particularly suitable for galvanized parts, since this process does not affect the protection.Our welding workshop is provided with:
