Welding Glossary


 * Joint ** – A joint is a Welding term which the junction of members or the edges of members, which are to be welded or have been welded.


 * Joined Build-up Sequence ** . The joined build-up sequence is the order in which the weld beads of a multiple-pass weld are deposited with respect to the cross section of the joint. See also block sequence and longitudinal sequence.


 * Joint Clearance ** – Joint clearance is the distance between the faying surfaces of a joint. In brazing this distance is referred to as that which is present before brazing, at the brazing temperature, or after brazing is completed.


 * Joint Design ** – The joint design is the joint geometry together with the required dimensions of the welded joint.


 * Joint Efficiency ** – The joint efficiency is the ratio of the strength of a joint to the strength of the base metal (expressed in percent).


 * Joint Geometry ** - The shape and dimensions of a joint in cross-section prior to welding.


 * Joint Penetration ** – The joint penetration is the minimum depth a groove or flange weld extends from its face into a joint, exclusive of reinforcement. Joint penetration may include root penetration. See also complete joint penetration, root penetration, and effective throat.


 * Joint Welding Procedure ** - The joint welding procedure refers to the materials, detailed methods and practices employed in the welding of a particular joint.
