摘要:
A tube over tube joint for an implement frame includes a self-fixturing weldable connector positioned between upper and lower tubes. Standard fillet welds connect the tubes to the connector. A unitary casting can be used made from material selected to optimize load transfer between the top and bottom tubes to improve the fatigue life of the joint. The casting is self-fixturing so the top tubes can be located by simply placing in the casting on the lower tubes. A tube end connector provides fixturing and weld surfaces for butt joints in planar frames. Outwardly extended weld edges on the connector increase resistance to parallelogramming.
