Assignee:
Novelis Inc. - Atlanta GA
International Classification:
B21D 22/02
B21D 37/16
B21D 37/16
Abstract:
Systems and methods of hot forming a metal blank include receiving the metal blank at a heater and positioning the blank adjacent a magnetic rotor of the heater. The systems and methods also include heating the metal blank through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal blank such that the metal blank is heated.
Method For Improving Quality Of Aluminum Resistance Spot Welding
US Patent:
2017023, Aug 17, 2017
Filed:
Feb 13, 2017
Appl. No.:
15/430854
Inventors:

JULIO MALPICA - Canton GA, US
RAHUL KULKARNI - Marietta GA, US
Assignee:
Novelis Inc. - Atlanta GA
International Classification:
B23K 11/10
Abstract:
Welding techniques, including, for example, resistance spot welding, can be used to join or weld two or more metal sheets together. A clamping force and an electric current can be applied to two or more sheets to create localized melting that combines the material of the two sheets. Applying a clamping force and a cooling current can include gradually decreasing the amount of the electric current applied to the weld while applying the forging force. By adjusting the amount of the electric current applied to the weld can allow the weld to cool gradually, which may reduce thermal stresses and allow the forging force to close cracks, pores, or otherwise be used to remove or prevent defects formed in the weld.
