Technical Committee 4 – Resistance welding

By discussing ongoing and completed research projects, the technical committees complement the work of the project-accompanying committees formed by the industrial companies. These are the bodies that actively accompany the work of the research units and the progress of the project from the beginning to the end of each joint industrial research project and, if necessary, intervene in a guiding manner to adapt the project to the current needs of the companies. The results of the research projects can thus be quickly transferred into the application of the companies. The research work of the Technical Committee will be closely coupled with the work of WG V3 with 8 subgroups.

A joint colloquium is held annually, where there is a lively exchange of information between research institutes and industrial companies. The expert committee supports appropriate measures for the transfer of research results. Process optimisations are a focus of the work of the technical committee.

Research fields:

• Quality assurance/non-destructive testing and welding process control/ online testing
• Research on occupational safety issues remains relevant (EMC/EMCE and other aspects of occupational safety)
• Determination of characteristic values remains a constant task, also for the application of simulation methods/simulation support/welding simulation for product optimisation
• Small part welding of electrical materials is further considered
• The focus is on the consideration of joining technology as part of the entire manufacturing chain, especially in connection with upstream forming technology or downstream painting
• High and ultra-high strength steel materials (with coatings) in combination with soft steel materials
• Quality assurance in resistance welding
• Consideration of current issues that arise on an ad hoc basis

An annual expert colloquium between WG V3 and the expert committee FA 4 on current research results takes place.
