Crimping mechanism between the stranded copper wires and brass terminals was investigated in terms of repulsion force acting on crimp terminations by way of the stranded wires. The repulsion force was estimated from the load-displacement curves recorded during the crimping process. We obtained the results as follows;(1) Repulsion forces, which were based on the elastic deformation of the strand composing wires, are observed between the stranded wires and crimp terminals.(2) The repulsion forces have a peak value at the compression ratio of 27% in the crimp terminations.(3) The suitable conditions of the contact resistance and the crimping strength are secured under the conditions of the peak value of the repulsion forces.

The first nuclear power station in Japan (Advanced Calder Hall type, 166 MW electric) is now under construction at Tokaimura.Construction of several new nuclear power stations will begin within a few years and also building project of the first nuclear powered ship (6500 G.T.) has been started in 1963.Al-killed steel plates 8094 mm thick were manually welded for Tokai reactor pressure vessel and its steam raising units were constructed with 5474 mm thick boiler plates using both submerged arc and manual welding. JPDR is a small BWR (12.5 MW electric), and the inner surface of its pressure vessel was stainless steel cladded by submerged arc process.Researches on the welding of the nuclear reactor have been extensively carried out by Japan Welding Engineering Society and also each industrial plant is doing its own researches. The study on the effect of irradiation on the properties of materials has been just started.

A new underwater plasma welding process has been developed. In this process, viscous liquid is used in place of shielding gas to protect the part being welded from the surrounding water and to stabilize plasma arc.Welding experiments are done by using steel for welded structure of 6 mm in thickness and it is ascertained that this process can be put to practical use.Main results are summarized as follows:(1) Water glass is used as a typical viscous liquid.(2) Water glass shielding for the part being welded has a marked effect on stabilization of underwater plasma arc.(3) Water glass shielding has an effect on heat insulating of the part being welded and lowers the solidification rate of molten metal. Owing to this feature, the weld metal does not include a blowhole and the maximum hardness of the heat-affected zone adjacent to the bond is lowered considerably.(4) The weld resulting from this process has excellent mechanical properties, and especially its ductility and notch toughness can be improved remarkably, compared with those of the weld resulting from nonshielding.(5) Coefficient of viscosity and flow (feeding) rate of shielding water glass should be selected properly. However, the proper range of combinations of viscosity and flow rate may be relatively wide.

鑄鐵瓦斯熔接の際熔着鐵の地をFerriteを多くし,黒鉛を可及的に多く出るものを得る目的で本研究を行つた・第一報にては(Si+Al)が3,4,5,7%なる場合の試驗を行つた結果(1)(Al+Si)=3.0~4.3%が熔接棒を作製し易い.(2)Al2%以上となると熔接操作が難しくなる.(3)(Al+Si)%が増す程黒鉛が多くなり且つ形状は細く一樣となる.(4)Alを加へると機械加工は母材と同樣で困難ではない.(5)母材との「なじみ」は何れも良好である.なることが判つた.
