摘要： PURPOSE:To reduce the contamination of slag in molten metal and the micro segregation in the molten metal by forming a cross sectional shape of a hallow part to the shape to satisfy a formula to shorten the extension of a flux column. CONSTITUTION:An inscribed circle 4 with the maximum diameter to touch internally the periphery 3 of the hollow part 2 formed by the sheath 1 is described and this radius is denoted by R. The distance from the center O of this circle 4 to a point A on the farthermost periphery 3 is denoted by L and the cross-sectional shape of the hollow part 2 is determined so that L/R is made to >=1.1. SPCC material is used as the sheath and wires with various hollow part cross-sectional shapes are manufactured and the welding is performed under prescribed welding conditions. By this method, the extension of the flux column is shortened and the contamination of the slag and the micro segregation are also reduced.

摘要： PURPOSE:To stabilize the product quality of the titled wire by specifying a ratio of an outside cross section of solid flux to an inside cross section of a pipe at the time of packing the solid flux in the longitudinal direction in the pipe to reduce the variance of a flux rate in the longitudinal direction of the pipe. CONSTITUTION:In manufacturing the flux-cored welding wire, the pellet-shaped or continuous solid flux 4 is packed in the longitudinal direction in the pipe 1. In this case, when the inside cross section of the pipe and the outside cross section of the solid flux 4 are denoted by S1 and S2 respectively, S2/S1=0.25-0.90 is formed and when the inside cross section of the pipe is formed to 0.5 S1 at least by reducing the pipe diameter, the solid flux 4 is pressed by the pipe 1 inside. By this method, the flux-cored welding wire with the stable product quality having little variance of the flux rate in the longitudinal direction of the pipe 1 is obtained.

摘要： PURPOSE:To improve the quality of a flux-cored wire having a joint by forming a groove part on the butting part of both lugs of a metal band and then, holding a lubricant on the groove part to perform the wire drawing. CONSTITUTION:A side 1b corresponding to the outer periphery of the wire of the metal band 1A is formed to the dimensions slightly shorter than a side 1c corresponding to the inner periphery and bent. Next, the flux 2 is filled in the wire and the metal band is worked by a forming roller to form the Y-shaped groove part 3 on the butting part of the lug parts 1d and 1d. Continuously, finally, the wire drawing is performed to produce the flux-cored wire having the joint. At the time of wire-drawing, the pressing force to act on the groove part 3 presses the lubricant against the slanting surface by the component and the lubricant can be prevented from peeling off. Accordingly, since the drawing property of the wire is improved, the quality of the flux-cored wire having the joint is improved.

摘要： PURPOSE:To manufacture the flux cored wire for welding a multiple tube by forming a band steel in semicircular arc shape with forming roll group, inserting a flux cored inner tube and hand-shaped adding material inside a semicircular arc shape band steel as well and performing a wire drawing as an integrated multiple pipe. CONSTITUTION:In manufacturing the flux cored wire for welding a multiple tube used for welding a low temp. steel, low alloy steel or high alloy steel, a band steel (h) is delivered from a supply stand S, and its sectional shape is formed in a circular shape 3 from circular arc shape 2 with forming roll groups 1-4 in order. At the time of its being formed in semicircular arc shape the inner pipe IP filled with the adding material AM of a linear or hand like Cr, Mo, etc., and a flux F is fed at the same speed as that of the band steel (h) steel and inserted onto the inner face of a semicircular arc shaped strip steel. It is subjected to a wire drawing by wire drawing devices 5-7, the multiple tube shape welding wire having the strip steel (h) as its sheath and incorporating the flux cored inner pipe IP and adding material AM is stably manufactured and wound on a winding machine 8.

摘要： PURPOSE:To prevent breaking of the wire of the time of wire drawing, and also to improve linearity and feeding property by specifying the hardness of a metallic sheath of a welding wire which has packed the inside of the metallic sheath with a flux of a granular shape. CONSTITUTION:A flux cored wire in which hardness of a sheath part is within a range of 245-290Hv not only executes smoothly wire drawing but also satisfies enough the linearity and the feed stability as a product wire. In this regard, in case of the wire in which hardness of the sheath part is under 245Hv, the wire is curved due to a feed resistance, he linearity drops or a buckling phenomenon occurs, and sometimes its feed cannot be executed. On the other hand, if the hardness exceeds 290Hv, the workability becomes inferior, and in the wire drawing process, breaking of wire is generated frequently, and the productivity drops.

摘要： PURPOSE:To enable highly accurate and stable measurement, by varying impedance detected when a flux-filled wire (FW) is passed through a coil. CONSTITUTION:When a metal wire is put into a coil through which AC current flows, a sort of induced current call as eddy current is generated. This eddy current changes depending not only on the level of the current applied to the coil but also on discontinuous portions of metal and variations in the shape of a sample when the current is constant. Utilizing the nature of the eddy current, changes in the thickness of skin metal can be caught as variations in the impedance (IP). So, first, FW carried with a reference thickness is inserted into a specified coil to measure IP at a specified frequency. Then, FW to be measured is measured on the same condition as the preceding one and the resulting IP is compared with a reference IP. Thus, the thickness at the part measured is judged and moreover very accurate calculation of the ratio of the flux can be done from the unit weight of skin metal at the measured part and the total weight per unit of the wire at the measured part.
摘要翻译：目的：为了实现高精度和稳定的测量，通过改变通量线圈（FW）通过线圈时检测到的阻抗。构成：当金属线放入交流电流流过的线圈中时，产生一种感应电流称为涡流。该涡电流不仅根据施加到线圈的电流的水平而且在电流的不连续部分以及当电流恒定时样品的形状的变化而变化。利用涡流的性质，皮肤金属的厚度变化可以被捕获为阻抗（IP）的变化。因此，首先将参考厚度的FW插入到指定的线圈中，以指定的频率测量IP。然后，在与前述相同的条件下测量要测量的FW，并将得到的IP与参考IP进行比较。因此，判断所测量的部分的厚度，并且可以从被测量部分的皮肤金属的单位重量和测量部分的每单位丝线的总重量，可以非常准确地计算通量比。
