Portable C WELTAC®

We recommend to remove the punched out slugs after each setting operation. To do so, pull the die out of the dome and remove the slug from the die.

No, the components do not need to be additionally treated for punching or welding. 

Yes, several aluminium layers can be punched at once. 

Since the element is additionally hardened, it can be installed in steel layers, provided that thickness and strength are suitable.

Yes; the top layer is not formed during a mere punching process. Even near the flange edge, no material damage is initiated. 

 If there is possible contact with corrosive media, common measures for corrosion protection and sealing must be taken.

Depending on the joining task, in most cases, the maximum shape change is realised in the weaker joining part. With a comparable element size, the joint characteristic values are the same or even higher. 

Depending on the required installations per year, we recommend to use a portable hand-held setting tool (can be combined with RIVSET® semi-tubular rivets) or a stationary automatic system.
