Newcor Invents Blemish-Free Weld Process for Aluminum

BAY CITY, MI--Newcor Bay City Div. has adapted its HY-PAK single-sided projec-tion welding process to sheet aluminum applications with critical surface finish requirements.

The result of a 2-year collaboration be-tween Newcor and Alcoa, the process produces a Class A surface finish during in-process fastening and hemming of aluminum panels, such as automotive closures and appliance "show" panels. Protective coatings on the welded sur-faces are not disturbed, and there is no distortion or "read-through" on hemmed surfaces. The process can also weld directly through adhesives, with no surface cleaning necessary.

HY-PAK is a resistance welding process that combines a high-energy, short-duration, unidirectional pulse with rapid electrode follow-up. The duration of the weld current pulse is so short that the current is concentrated at the weld point and minimal heat is transmitted to the adjacent component and electrode material.

The ASSEMBLY Show South

ASSEMBLY is thrilled to return to the Music City Center in Nashville, TN for The ASSEMBLY Show SOUTH on May 1-2, 2024. This is a booming time for manufacturing and the U.S. South is right in the heart of the action. According to ASSEMBLY’s most recent annual capital spending survey, the South is projected to account for 31 percent of total spending this year, marking the fifth straight year this region has accounted for at least 30 percent of capital spending in the U.S.

In this session, manufacturers will learn how Quality function deployment (QFD) can transform consumers’ qualitative demands into quantitative parameters that will shape the design of their product and, ultimately, their manufacturing process.
