Load-bearing structures of superconducting magnet systems involve the manufacture of defect-free fusion welds in nitrogen-strengthened austenitic stainless steels in thicknesses to 150 mm. These welds must be capable of fracture-safe operation at 4 K at stresses close to yield and must resist failure caused by growth of fatigue cracks to critical sizes and rapid propagation to fracture. Many factors are involved in making satisfactory welds for this purpose; they have been examined and discussed in Refs. 1 and 2, for example.
