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 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。

摘要： PURPOSE:To prevent thermal influence to a flux by the cavity formed in the part right under the weld line and to obtain a flux cored wire having good quality by depressing the central part of the surface of the flux packed in a curved hoop in the longitudinal direction thereof prior to seam welding. CONSTITUTION:The crest-shaped surface of a flux 4 charged onto a U-shaped hoop 3 is pushed by a shaping jig 8 to form a trough 9. The hoop 3 is then curved by squeezing rolls and is seam-welded along the longitudinal direction thereof. The shaping of the peak surface of the flux 4 in this case may be accomplished by using a block-shaped shaping jig 8 or a roller-shaped shaping jig 8 or feeding forcibly a gas such as Ar or CO2, etc. and shaping the peak part. Any means is usable as far as such can shape the peak of the flux to a hollow line.

摘要： PURPOSE:To avert bridging of a magnetic flux in the production of a flux- cored welding wire wherein a hoop is squeezed and is pad-welded by providing a grounding point right under the welding point or the bottom surface on the downstream. CONSTITUTION:An electricity conducting roll 10 is pressed to the rear surface of a pipe right under a welding point P or on the downstream thereof in a stage for producing a wire 3 for electrical welding of a joint part 7a by bending a steel strip 7 contg. a flux F and drawing the same with a roll 6 group. The welding current flows to the roller 10 without spreading too much like I2 or I2b and therefore no magnetism is generated on the upstream of the part in contact with the steel strip, and the bridging by the flux in the weld zone P is prevented. The wire having no defect, etc. is thus obtd.

摘要： PURPOSE:To maintain the packing rate of a flux constant by determining the theoretical value of a flux mass from the size factor and specific gravity of a belt-like wire and controlling the feeding out rate of the flux so as to decrease the deviation between said value and the current value of the flux mass. CONSTITUTION:The length, width and current length of a belt-like wire 2a are measured at all times with a mass detector 6 and are fed to a control device 7 which calculates the current value of the mass per prescribed length of the wire 2a from the same and the specific gravity of the wire 2a and calculates the theoretical value Mfk of the flux mass corresponding to said value as a max. target value. On the other hand, the feeding out rate of the flux (the current value of the mass) Mfa which is supplied currently onto the wire 2a from the feeding out part 8a of an electromagnetic feeder 8 is measured and is fed at all times to the device 7. The arithmetic processing of (Mfa-Mfk) is performed in the device 7 to determine a deviation value + or -DELTAMf, and the supply rate of the flux from the feeder 8 is so controlled as to maintain the value DELTAMf within the prescribed value.

摘要： PURPOSE:To enable the production of a flux cored wire having high quality in the stage of producing the flux cored wire for welding, by packing a flux in band steel which is curved to a tubular shape, and sealing or brazing the butt parts on both side edges of the band steel with another band steel. CONSTITUTION:The band steel W-1 un-coiled from a spool 1 is formed to a tubular shape, and a flux F from a flux box 2 is packed into the butt parts of both edges from the non-contact part thereof. The band steel W-2 for sealing un-coiled from a spool 1' is superposed on the butt parts of the tubular band steel and is curved with a curving roll so as to enclose the flux cored band steel W-1. Such band steel is drawn with drawing dies 5a-5c down to a prescribed outside diameter. The butt parts of the flux cored tubular steel pipe may be sealed by brazing. The deterioration in the quality of the internal flux owing to the infiltration of moisture into the tubular band steel is obviated.
