Abstract
A welding fixture by which two elongate members are manipulated in a manner to become butt welded together. Two gripping members in the form of groups of spaced slip assemblies are enclosed in mounted relationship within a housing. The slips of each group circumferentially extend about a longitudinal axis of the housing, with the slips of each group being radially spaced from the longitudinal axis of the members to be joined. A first group of slips are mounted for movement within a plane which is perpendicular to the longitudinal axis of the members to be joined. The other group of slips are likewise arranged within a plane spaced from and parallel to the first plane. All of the slips are moved with great force towards the longitudinal axis of the members to be joined. The fixture includes means by which the members are moved toward one another with great force. Each group of slips further include an electrical contact which provides a source of current to each of the members to be joined. The confronting ends of the members to be butt welded are received within the opposed ends of the housing, and extended into close proximity respective to one another, whereupon each group of sli…
