System and method for controlling and coordinating welding-type processes and gouging-type processes

A multi-operational welding-type system including a user interface supported by a support structure and including a first user interface device moveable between a welding position, a gouging position, and an off position, and a second user interface device configured to alter operation parameters of the multi-operational welding-type system. A controller is supported by the support structure and monitors the position of the first user interface device and utilizes the operational parameters supplied via the second user interface device. The multi-operational welding-type system may perform only one of a gouging-type process and a welding-type process at a given time depending on the position of the first user interface device.

20220055142 · 2022-02-24 ·

A welded assembly includes a first component including an aluminum material, a second component including a stainless steel, and a third component including a steel material. An ultrasonic weld is formed between the first and second components to join them and form a stack. A sealant and/or adhesive may be applied to the stack. A resistance spot weld is used to join the third component to the stack to form the welded assembly. The resistance spot weld encompasses a portion of the first, second, and third components, and a portion of the ultrasonic weld. The resistance spot weld is completely encompassed in the welded assembly, and thus is sealed from electrolyte in a surrounding environment.
