Conclusion
The resistance welding process can deliver a reliable and repeatable joining solution for a wide range of
metal joining applications. Defining the optimum welding process and best production settings can be
achieved through a methodical and statistical approach. Time spent up front in weld development will
ensure a stable welding process and provide a substantial return in quality and long term consistency.
Welding problems can more easily be identified and solved if sufficient experimental work is carried out
to identify the impact of common variables on the quality and variation of the welded assembly. Amada
Weld Tech frequently uses the Screening DOE tool to establish the impact of key variables and to assist
customers with troubleshooting. Often, the testing described above will provide the information and
understanding to predict common failure modes and causes.
