摘要： PROBLEM TO BE SOLVED: To provide a build-up method by which in the case of build-up working each valve-seat part in a cylinder head, the development of crack into the build-up layer caused by a heat transmission from the other valve seat part is prevented and also, the strain of the cylinder head is reduced. SOLUTION: Since the build-up orders of respective valve seat parts 1-8, 1a-8a, are set so that the heat input of laser beam to the valve seat part built up at the number (n) is not transmitted into the valve seat part buit up at the number (n+1), the development of the crack to the build-up part of each valve seat part 1-8 and 1a-8a, is prevented and also, the strain of the cylinder head 10 can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a method of welding and repairing a gear box of a rolling stock, which eliminates a fear of cracking at the time of welding, achieves uniform hardness at a welding portion, and is free from degradation of strength of a base metal.
SOLUTION: There is provided the method of welding and repairing the gear box of the rolling stock, which is formed of spheroidal graphite cast iron. According to the method, a defective cast portion of the gear box is subjected to gas welding by using a welding rod formed of a common material, and heated to a temperature of 890 °C or more, followed by holding the same state over a predetermined period. Then the gear box is furnace-cooled down to 750 to 820°C, and held at the same temperature over one hour or more, followed by air-cooling the same. According to the method, the gear box for the rolling stock can be formed of the spheroidal graphite cast iron of which a large vibration damping effect can be expected compared with a gear box formed of cast steel.

摘要： PROBLEM TO BE SOLVED: To solve the prolem that ductile cast iron metal materials, conventional friction welding cannot assure the resultant base metal of even strength and elongation. SOLUTION: Two ductile cast iron materials, either or both of which contain 2.5% or more silicon are set to make a tip-to-tip contact. Then, they are subjected to friction force to generate welding heat under the friction pressure of 10-60 MPa, at the friction speed of 4 to 8 meter per second and at the burn- off speed of 0.15-0.7 mm per second, and thereafter are held under the upset pressure of 20-80 MPa. While this prevents the production of pearlite in the base metal, ductile ferrite phase can also be retained in the base metal to maintain necessary strength and elongation.

摘要： PROBLEM TO BE SOLVED: To strongly weld a ring regardless of existence of zinc on a tube surface by using shield gas with CO2 and O2 mixed with Ar, at the time of welding by press-fitting the ring on the outer periphery of the inserting hole of a cast iron tube. SOLUTION: The ring 12 is press-fitted onto the outer periphery of the inserting hole 9 of the cast iron tube 8. The ring 12 is constituted of a cylindrical body and formed with an outer peripheral groove 15 on this outer periphery and the thickness at the bottom part 16 of this outer peripheral groove 15 is made thin as much as possible. Further, the part 17 in the ring 12 corresponding to the tip side of the inserting hole 9 is projects from the part 18 corresponding to the tube barrel part side. At the time of press-fitting the ring 12 to the position where the end surface 21 of the ring 12 is on the same surface with the tip part 22 of the inserting hole 9, molten metal is poured into the outer peripheral groove 15 of the ring while rotating the tube 8 to melt the bottom part 16 of the outer peripheral groove 15 and the surface part of the inserting hole 9. At this time, as the shield gas, the gas with CO2 or oxygen mixed with Ar is used. By this method, the sufficient detaching preventing performance is given to a tube joint.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of cracking in a base material even if preheating is not executed, to impart excellent machinability after cladding by welding to a welding material and to stabilize its hardness after supercooling treatment, in a component deciding method by a Schaeffler diagram, by specifying the Ni equivalent and Cr equivalent and deciding them so as to lie in an austenitic region. SOLUTION: In a welding material for hardening cladding by welding in which a cast iron base material is clad by welding without preheating the base material and is thereafter hardened by supercooling, as for the componental compsn. of the material, the components are decided so as to satisfy the Ni equivalent and Cr equivalent contained in the region in a Schaeffler diagram by which the difference in the hardness before and after the supercooling in a state of being clad by welding is regulated to a prescribed value or above. In this method, Ni equivalent is decided to 34 to 37.5 and the Cr equivalent to 3.5 to 4, and, also, they are decided to lie in an austenitic region (above the boundary line La). Furthermore, at the time of adding Co by 0.5 to 1.5wt.%, the hardness difference Hv 200 can be secured even in the case the Ni equivalent is increased to about 38.
