The benefits of Low Force Welding over traditional fusion/solid-state bonding processes
The benefits of Low Force welding over traditional fusion/solid-state bonding processes and its potential future applications. This presentation provides an up to date overview of the Low Force welding process development conducted by MTI adopting linear and reciprocating relative motion, while using inductive and resistance preheating methodology. The associated advantages and disadvantages of the relative motion and pre-heating combinations are identified and evaluated with respect to weld interface suitability and future industrial applications.
Multiple commonly used aerospace materials have been evaluated during this multi-year development program to provide a wider understanding of the process capabilities. The data acquired during the weld development program has constructed a robust and comprehensive understanding of how weld parameters relate to the post weld mechanical performance of the resultant bond. This data is also drawn upon to design manipulated parameter sets that produce welds with tailored characteristics specific to a desired performance or application.
The presentation includes an assessment of key issues associated with traditional welding processes and how Low Force Technology can alleviate these by exploiting the positive attributes of fusion and solid state joining and combining them to form a single process. The joining of a new “interrupted rotary weld geometry” previously unweldable is discussed with supporting data associated with the post weld characteristics and performance.
