scope:

In this Technical Code the non-contact heated tool butt welding and the requirements for devices and machines are described. With the mentioned features the processor can check which devices or machines are most suitable for the safety realizable performance of his welding works appropriate to the materials involved.

This Technical Code relates to methods and the different types of processes of heated tool butt welding where the heating up of the joining areas is done without any contact. Machines, devices and their parameters for the welding of pipeline components, sheets and other components out of PP (PP-H/PP-B/PP-R) and PVDF are described. Occasionally the system dependency according to the manufacturer's instructions with material combinations of PP and PVDF have to be considered. Concerning the welding suitability of materials PP and PVDF see the topic "scope" in DVS 2207-11 and DVS 2207-15.

With the welding of other plastics e. g. PFA, E-CTFE the parameters have to be checked and possibly adjusted. The welding joint quality must be proved depending on the system (machine, parameters, component).
