Abstract
A welding fixture including an electromagnet, a non-magnetic support configured to receive at least two sheets of material to be welded, and one or more clamping shoes configured to cooperate with the electromagnet to apply a clamping pressure to the at least two sheets of material and the non-magnetic support as a result of a magnetic force produced by the electromagnet is provided. A first of the at least two sheets of material is in contact with at least one of the one or more clamping shoes, and a second of the at least two sheets of material is in contact with at least the non-magnetic support. The one or more clamping shoes being shaped such that a perimeter defined by the one or more clamping shoes is located in the vicinity of a defined weld line to be welded on the at least two sheets of material, the weld line remaining substantially free from optical obstruction during production of the magnetic force.
