Our combination of experience and equipment offers you, the customer, a wide range of solutions and capacities in bending and forming. Whatever your need, whether large projects or small components, we form yourrecent experiments and FE analysis on single-material to your specifications. At Advanced Bending Technologies, the job is notsided fillet welds around the ends of HSS that (a) complete until we achieve your requirements in accuracy and repeatability. confirmed bending about the weld axis occurs when the HSS wall is in tension (see Figure 5), and (b) showed, in some cases, that the welds did not develop the same strength increase at failure predicted by the sin factor.
