摘要： PURPOSE:To eliminate the generation of a crack in the outside circumferential edge part of a recessed spherical surface to be subjected to a TIG treatment by blowing side gas to the part near said edge part and an electrode thereby preventing the arc wandering to be caused by the high frequency during arc generation. CONSTITUTION:The electrode 9 of a TIG torch 8 is directed to the recessed spherical surface 5 of an arm 1 and shielding gas 11 is fed thereto from a nozzle 10 to generate an arc. An arm 1 is rotated around the axial center of the surface 5 to form a bead 12. A side nozzle 16 is directed, with the surface 5 backward, to the part near an outside circumferential edge part 13 and the electrode 9, and the same side gas 17 as the gas 11 is ejected in about 2-3sec before the impression of the high frequency during the arc generation. The gas is stopped in about 0.5sec after striking. The impact of the ion generated in the above-mentioned proximity part and the release of thermion are thus obviated and the generation of arc wandering in the part 13 is prevented. The crack likely to be generated in the outside circumferential edge part 13 in the stage of a hot coining treatment is thus eliminated.
摘要翻译：目的：为了消除通过将侧气体吹向靠近所述边缘部分的部分的电弧进行TIG处理的凹入球形表面的外周缘部分产生裂纹，从而防止由于电弧产生时的高频。构成：TIG焊炬8的电极9被引导到臂1的凹入的球形表面5，并且保护气体11从喷嘴10供给到其中以产生电弧。臂1围绕表面5的轴向中心旋转以形成胎圈12.侧面喷嘴16与表面5向后指向靠近外圆周边缘部分13和电极9的部分，并且相同气体11在电弧产生期间的高频印象之前的大约2-3秒内被排出。在冲击后约0.5秒内停止气体。因此避免了在上述接近部分中产生的离子的影响和热离子的释放，并且防止了在部分13中产生电弧徘徊。因此，消除了在热压缩处理阶段在外周缘部13产生的裂纹。

摘要： PURPOSE:To make texture having high attacking property to the other by remelting the local section of a metallic member contg. metallic carbides by using a high density energy source then allowing the same to cool of itself. CONSTITUTION:A metallic member contg. coarse metallic carbides having high attacking property to the other such as, for example, Fe3C, Cr7C3 or the like (e.g.; cast iron, carbon steel) are prepd. The local section of the member to be treated consisting of such metallic member is remelted by using a high energy source, more preferably, pulse TIG arc. The arc is generated in this case by applying electric current between the material to be treated as a (+) electrode and a TIG torch as a (-) electrode, and flowing a shielding gas consisting usually of gaseous Ar between the same. The material to be treated or the TIG torch is moved to the section of the shape where the metallic carbides are desired to be fined upon generation of the arc to remelt the shape on said shape alone. The current supply is turned off after the end of the remelting, and the movement of the material to be treated or the TIG torch is stopped and the member is allowed to cool of itself, whereby the metallic member fined partially with the metallic carbides is obtd.

摘要： PROBLEM TO BE SOLVED: To provide a partial stress relieving method for a weld zone by which residual tensile stresses partially produced in a weld zone are easily relieved in the same process. SOLUTION: A bracket 2 is fillet welded to a base metal 1, and a surface of the base metal 1 a distance L away from a toe of a formed bead part 3 is partially heated by arc welding or other way using the same electrode 5 as an electrode used for a fillet weld between the base metal 1 and the bracket 2, in the same process of this fillet welding, namely, at the same time as the fillet welding between the base metal 1 and the bracket 2 is performed, or, after this fillet welding. The residual tensile stresses caused by the fillet welding on the base metal 1 are compensated and relieved by applying a residual compressive stress produced by partial heating.
