Alternative Joint Solution for Zinc Coated PHS and Low Alloy Sheet 2015-36-0303
Nowadays, meeting the increasing vehicles’ body structure performance requirements without affecting the vehicles’ mass has become a challenge for OEMs. To do so, automakers are deploying new and different sorts of materials combinations on the Body structure.
It is known that the usage of high strength steel stamped parts, such as Press Hardened Steel (PHS), in specific Body structure regions, may reduce the need of local reinforcements or further parts, allowing the vehicle to reach the desired performance level while avoiding mass increase.
One of the most common methods used to join PHS parts and cold rolled stamped parts is spot welding. This paper studies alternative joint methods between PHS parts and low alloy sheet metal stamped parts, both zinc coated, when spot-weld application is not feasible due to specific body structure joints constructions.
