ABSTRACT:
The method and structure permit the testing of welds forming the structure. The structure comprises a base plate, a longitudinal member on the base plate, a web having an opening positioned over the longitudinal member, and a lap collar having an air hole and covering the web opening. An air channel is formed by welds formed between welded abutting surfaces of the base plate and the web, and between the web and the longitudinal member, and between the lap collar and the base plate, and between the lap collar and the longitudinal member. The air channel is continuous along the entire length of the web and base plate thereby permitting the detection of defects in the entire length of welds when the air channel is pressurized through the air hole.
