Claim:
1. A welding fixture, comprising: 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; wherein 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 wherein 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.
