An article written by our very own, Jeff Beach, was featured in New Equipment Digest this week highlighting the changes manufacturers are making in order to accommodate to the latest trend in lightweight vehicle structures.
Here’s an excerpt from the article entitled, “How Metal Composition is Changing Welding Technology in the Automotive World”, where Jeff dives into the process of adapting to new metals in the manufacturing industry:
Manufacturers and suppliers are making significant changes to their welding processes to accommodate the increase in production of lightweight vehicles. How? By redesigning resistance welding guns to make them suitable for the assembly of aluminum alloy vehicles.
This change in vehicle structure requires current resistance spot welding techniques, normally applied to steel, to be transferred directly to aluminum alloy. However, more than double the secondary amperage is needed to weld aluminum, due to its composition, causing manufacturers to go back to the drawing board and reconsider design methods that have been the industry standard for many years.
