  • the structural part can be performed without adapter in low material thickness up to the fitting zoom.
  • the distances chosen for joining also include the possibility of connecting more than two components at the joints, i. For example, the second fitting part, the reinforcing element and the structural part at the same time, in particular with a common weld.
