A method of manufacturing a structural assembly is provided. In one embodiment, the method includes the steps of providing first and second structural members having preselected shapes and dimensions. The first structural member defines a first raised portion and the second structural member defines a second raised portion. According to one embodiment, the providing step includes forming the first and second structural members into preselected shapes and dimensions. The first and second structural members can comprise plates, T-stiffeners or tubular members. The first raised portion of the first structural member is positioned adjacent to the second raised portion of the second structural member following the providing step to thereby define an interface therebetween and wherein the first and second raised portions define a substantially consumable weld land. Thereafter, the first and second structural members are irradiated with a high-energy source along the interface to thereby substantially consume the weld land and join the first and second structural members to form a structural assembly. The first high-energy source preferably comprises an electron beam or a laser.
