Document Type and Number:
Japanese Patent JP7332050
Kind Code:
B2
Abstract:
To provide an element for friction element welding.In performing friction element welding of a sheet set constituted by two or more metal sheets, an element is used that includes a round columnar mandrel to be press penetrated into the sheet set; a disc-shaped collar provided at an upper end face of the mandrel; and a conical pin extending from a lower end face of the mandrel. The element has a plurality of fluidized-metal discharge grooves arranged spirally in a flat area of the lower end face of the mandrel, the flat area excluding the pin.Alternatively, the element may include a round columnar mandrel having a lower end face that forms a conical face with an apical angle αm, the conical face having one or more pairs of chippings discharge grooves or further having a plurality of cutting edges, the chippings discharge grooves each extending in a curved manner from an apex of the conical face.
