Experimental Study of Fillet Weld Undercut Effects on Welded Tubing Structures Under Centric and Eccentric Cyclic Loading.

摘要

The effects of weld undercut defects on the structural behavior of twelve welded tubing test specimens subjected to centric and eccentric cyclic loadings were evaluated. The test program included the design, fabrication, and testing of one group of six fillet-welded tubing specimens and one group of six reinforced partial-penetration, groove-welded tubing specimens under centric and eccentric loading. Each group consisted of three centrically loaded specimens with 0, 1/32-, and 1/16-in undercuts and three eccentrically loaded specimens with 0, 1/32-, and 1/16-in undercuts.
