Abstract:
A method for welding together two workpieces. 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.
