FIELD WELDING PROCEDURE TEST OF HYBRID JOINTS USING 3% NI-ADVANCED WEATHERING STEEL

Abstract

This study is the report that carried out field welding procedure test in a hybrid joint of the bolt joining and the welding joining with 3% Ni-advanced weathering steel. At first, this study showed a welding characteristic of 3% Ni-advanced weathering steel. Next, we performed welding execution of a flange and a web after having tightened a bolt of a longitudinal rib and a horizontal stiffener as application procedure in a hybrid joint. At that time, we measured the shrinkage by welding, and the sliding situation of a bolt. We also carried out slip test of the join surface that sliding produced once, and we made it clear that fall degree of a sliding proof stress. Based on these results, we suggested application procedure in a hybrid joint of the bolt joining and the welding joining in the construction spot.
