Abstract

The invention relates to mechanical dimpling of vapor expression in welding. A method for welding together two workpieces is provided. The method includes stamping, using a stamping system, a first workpiece comprising a material that creates vapor when melted, such as zinc. The first workpiece is stamped at a first preselected region to form a plurality of depressions in the first preselected region. The method further includes positioning the first preselected region adjacent a second preselected region of a second workpiece. After stamping and positioning as such, the method includes applying energy to at least one of the first preselected region and the second preselected region to melt material of the first and second workpieces to form a joint connecting together the first and second workpieces. Based on the configuration and arrangement created, any vapor formed by molten material vents from the joint being formed, between the depressions formed, and away from the first and second workpieces.

Description

technical field [0001] The present invention relates generally to welding, and more particularly to systems and methods for promoting the release of unwanted vapor by-products in welding materials, such as zinc. Background technique [0002] Welding is a common way of joining like or dissimilar materials across a wide range of industries. Energy for welding can be applied in various ways, for example by laser or ultrasonic vibrations. [0003] In car manufacturing, steel or metals such as aluminum are being used. The demands and challenges associated with welding multiple materials together are increasing. [0004] Workpieces joined by welding include such as instrument panels and door panels, lights, air ducts, steering wheels, trim, floor or other vehicle storage compartments, trim components, exterior parts, and engine components. For example, in the case of engine components and other under-the-hood (UTH) applications, workpieces are continuously configured and develo...
