摘要： PURPOSE:To perform stable sealing without generating change in structure and blowholes by attaching a cooling plate formed of copper to a palladium capillary except the sealing part at the tip, inserting a cooling bar formed of copper into the capillary according to need and sealing the tip of the capillary. CONSTITUTION:A drilled hole into which a palladium capillary 1 is penetrated is punched in a cooling plate 3 formed of copper and a capillary 1 is projected from the hole. A cooling bar 4 formed of copper is inserted into the capillary 1 according to need and a sealing part 2 projected therefrom is sealed. The cooling in the part 2 is thus accelerated, by which the generation of a change in the structure and blowholes in the part 2 is prevented and the shape in the part 2 is stabilized.
摘要翻译：目的：为了进行稳定的密封，不会发生结构和气孔的变化，将由铜形成的冷却板附着在除了尖端处的密封部分之外的钯毛细管上，根据需要将铜形成的冷却棒插入毛细管中并密封尖端的毛细管。构成：将穿过铜毛细管1的钻孔冲压在由铜形成的冷却板3中，毛细管1从孔突出。由铜形成的冷却棒4根据需要插入毛细管1中，从其突出的密封部2被密封。因此，部件2中的冷却因此被加速，从而防止了部件2中的结构和气孔的变化的产生，并且部件2中的形状稳定。

摘要： PURPOSE:To direct exactly the welding arc to the groove part of a pipe material, by controlling the driving and rotating of a holder and the driving of a slider and a carriage by the signal from a limit switch. CONSTITUTION:A guide rail 18 is provided to a slider 17 which is freely slidably engaged at both end parts with a guide rail 12 and an auxiliary rail 14 and is screwed to a feed screw shaft 13 connected to the 1st rectilinear driving motor 16; furthermore, a feed screw shaft 19 in parallel with the rail 18 is freely rotatably mounted thereto. Guide rails rectangular to the rails 12, 18 are protrusively provided to a carriage 21 screwed to the shaft 19 connected to the 2nd rectilinear driving motor 20 and further a holder 24 connected to a rotating and driving motor 23 is freely drivably and rotatably supported with a support plate 25 thereto.
摘要翻译：目的：通过控制保持架的驱动和旋转以及通过限位开关的信号驱动滑块和滑架，准确地将焊接电弧直接引导到管材的凹槽部分。构成：导轨18设置在滑块17上，滑块17在导轨12和辅助导轨14的两个端部处可自由滑动地接合，并被拧到与第一直线驱动马达16连接的进给螺杆轴13上; 此外，与轨道18平行的进给螺杆轴19可自由旋转地安装在其上。与轨道12,18成直角的导轨突出地设置在与连接到第二直线驱动电动机20的轴19螺纹连接的滑架21上，另外，与旋转驱动电动机23连接的保持件24可自由地驱动和可旋转地支撑支撑板25。
