ABSTRACT:
A fixture for welding a grounding connector to a structural steel member is disclosed. Such fixture is formed of a magnetic material so that the fixture is attracted to, and retained upon, the steel member. A chamber is defined within the rectangular body of the fixture, and an inlet passage in the front of the fixture receives one end of the grounding connector. Thermite powder is introduced into the chamber, and an igniter cap delivers a spark to the powder, to ignite same, thereby producing a molten mass of metal. The metal flows the fixture and bonds the grounding connector and the fixture to the structural steel member. The method of utilizing such single-use fixture is also disclosed.
