Method and apparatus for welding a metal fastener to a metal member |
摘要 |
A method and apparatus for projection welding a metal fastener (e.g., a nut) to a metal member (e.g., a sheet) is disclosed. The apparatus includes a first electrical contact and a locator assembly having a second electrical contact. For welding the fastener to the member, the locator assembly aligns through-holes of the fastener and sheet and a current is passed through protrusions of the fastener. In turn, the protrusions are softened to bond with the member.
