摘要： A method for bending strands of material. The method includes providing a first pair of opposing dies each comprising a first surface corresponding to a first pair of predetermined bends to be formed in a first strand of material, positioning the first strand of material at least partially between the first pair of opposing dies, moving the first pair of opposing dies with respect to one another to impart the first pair of predetermined bends in the first strand of material, providing a second pair of opposing dies each comprising a second surface corresponding to a second pair of predetermined bends to be formed in a second strand of material, positioning the second strand of material at least partially between the second pair of opposing dies, and moving the second pair of opposing dies with respect to one another to impart the second pair of predetermined bends in the second strand of material.

摘要： A brazing process is provided that addresses the braze joint failure problems encountered in some multi-nozzle combustion end covers. The brazing process embodying the invention provides optimal, predictable low cycle fatigue joint life in particular when brazing 304L stainless steel parts using Amdry 915 braze alloy. The invention was realized in particular in the combination of and application of tightly controlled vital variables of gap, braze alloy, braze peak temperature hold time, cooling (quench) rate, surface finish and braze media to optimal limits for the process parameters. The process provides robust/reliable design limits for braze joints experiencing stress during operation.

摘要： A combustor/transition piece for a gas turbine including a double walled structure having a plurality of cooling channels, both axially and, in some cases, circumferential cross-flow passages positioned between the structure's inner member and the outer member to provide cooling air thereto, are formed in the area between the inner member of the combustor and the outer member thereof. The passages preferably extend both axially and circumferentially with respect to the direction of flow through the combustor/transition piece. The axial passages extend completely from one end to the other and the circumferential passages extend around the circumference of the combustor/transition piece. The addition of a circumferential cross-flow passage connecting axial flow coolant passages in double wall turbine components can prevent combustor/transition piece part failure due to axial passage inlet blockage without affecting normal, unblocked cooling. Double wall cooling structures are constructed using two unbonded members. The inner member is machined to form cooling passages. Differential thermal expansion (expansion of the outside diameter of the hot inner wall until contact is established with the inside diameter of the cooler outer wall) keeps the cylinders held tightly together. Double wall cooling structures are also constructed using two members shrink-fitted and then bonded together such as by welding. The inner member is machined to form the cooling passages. The improved thermal contact between the outer and inner members due to the joint reduces the thermally induced stresses in the two members.
