Abstract

In various embodiments, a method of joining clad structures includes providing first and second clad structures each comprising a protective layer disposed only partially over a steel layer such that an edge region of the steel layer is exposed, joining the first and second clad structures at their respective edge regions, thereby forming a joint, and cold spraying a metal powder over and in contact with (i) the joint, (ii) the edge regions, and (iii) the protective layers of the first and second clad structures, thereby directly connecting the protective layers of the first and second clad structures with a layer of unmelted metal powder.
