    摘要： In the method of manufacturing a superconducting coil, a superconducting line coated with an insulating member is contained in a groove formed on a surface of a stainless steel plate, and a stainless steel lid is fitted in outer side of the superconducting line in an opening in the groove. The lid is formed to fit in the groove. Then, the plate and the lid are welded to seal at joint sections. The welding is conducted using a plurality of heat sources including a laser and an arc so that melting depth at the joint section is within a predetermined range. The lid may have two joint sections, and the welding of the joint sections of the lid may be conducted simultaneously. The plate may have a plurality of grooves, and the welding of the joint sections of the lid may be conducted simultaneously.

    摘要： A method is provided, which ensures reliability during manufacture and in the use environment, and allows affording erosion prevention capability in an inexpensive manner, to an erosion-susceptible portion such as turbine rotor blades. An erosion preventive section 4, comprising a lower layer (low-hardness layer) 2 of an austenitic material, and an upper layer (hard layer) 3 of a hard material, such as stellite, harder than the low-hardness layer 2, is formed by laser build-up welding on a portion, which is susceptible to erosion caused by liquid droplets and solid particles in a use environment, of a target member 1 such as a turbine rotor blade. Laser build-up welding is carried out through irradiation of a laser beam from a laser light source 6 while a welding material supply means 5 supplies an austenitic material and a hard material in the form of, for instance, a rod, powder or the like.
