Title: Welding method for sheet steel
Inventor: FUJIOKA TADASHI
IPC: B23K9/025
Filed: 1986-02-26
Abstract: PURPOSE:To prevent unevenness of a bead or a drop of a globule by supplying a welding wire to a molten pool intermittently in conformity with a fall of a welding current waveform when TIG-welding a lap of sheet steel. CONSTITUTION:The welding wire is supplied to the molten pool at a fixed speed simultaneously with the fall of a welding current where a base electric current and a peak electric current are allowed to flow alternately in a pulse state and supply of the welding wire is stopped before a rise of the next welding current waveform. In this way, when the welding wire is supplied to the molten pond intermittently in conformity with the fall of the welding current waveform, the base electric current is supplied as the welding current and the quantity of arc heat is reduced and the wire tip is not molten by the are heat as long as the welding wire is supplied to the molten pond. Accordingly, the unevenness and perforation of the bead are certainly prevented.

Abstract: PURPOSE:To improve the shape control accuracy by detecting a temp. of rolling material in the inlet side of a tandem rolling mill and controlling a bending pressure as well as changing a pattern of a shape control gain at respective stands based on the above detected temp. CONSTITUTION:A thermometer 16 is installed in the inlet side of a tandem rolling mill 14 consisting of stands 15a, 15b and a shape control gain changing device 17 and a bending pressure controller 18 are also installed for the stands 15a, 15b.

Title: Drive control circuit for electromagnetic vibrator
Inventor: OKI EIJI
IPC: B65G27/32
Filed: 1990-02-20
Abstract: PURPOSE:To obtain a prescribed amplitude even at variation of voltage by arranging a rectifying circuit between a gate pulse generating circuit and an AC power source, supplying the DC output to the gate pulse generating circuit, and adjusting the gate pulse phase so as to correct current variation accompanied with voltage variation of the AC power source. CONSTITUTION:In state of closing of a switch 10, voltage Va of an AC power source 1 is supplied to a pulse signal generating part 12 through all wave rectification. The pulse signal generating part 12 outputs a gate pulse G of (ga) sequence by a pulse signal from a pulse width control signal generating part 15. When the power source voltage rises from Va to Vb, the pulse signal generating part 12 moves the gate pulse (ga) in the direction of compensating the varied voltage portion as shown in the arrow mark to generate a gate pulse of (gb) sequence. Hereby, coil current is reduced by voltage rise portion to obtain a prescribed torsional vibration force. By this constitution, a prescribed amplitude can be always obtained even against variation of the AC power source.

Filed: 1986-02-26
Abstract: PURPOSE:To absorb axial direction thrust generated in the guide screw axis by fixing the guide screw axis by means of a bearing in which belleville spring is interposed between a bearing retainer and a ball bearing. CONSTITUTION:Collars 6d, 6e of a female screw nut 6 are fixed to a coupling tool 15 by means of a fixing bolt 17 and a table 7, a coupling tool 14 and the female screw nut 6 are integrated, then the table 7 reciprocates with the reciprocation of the female screw nut 6. The contact pressure during a guide screw generated between a thrust bush 12 and a bearing retainer 11 is always governed by a belleville spring through a ball bearing 10. Therefore, if the spring reaction force larger than the table transfer resistance exists, the thrust bush 12 and the bearing retainer 11 are always contacted each other. And even if the change in external force such as cutting resistance etc. is generated during transfer of the table and a force generating thrust motion works, the force is absorbed by the belleville spring 13.

Abstract: PURPOSE:To permit local restriction of a normalizing treatment of an electric resistance welded steel pipe for boilers and heat exchangers and to reduce the heat treatment cost thereof by decreasing the content of impurity S in said steel pipe as far as possible and incorporating a specific ratio of Ca therein so as to comply with the content of S. CONSTITUTION:Steel materials having the compsn. contg., by weight %, <0.20% C, <0.35% Si, <1.70% Mn, <0.015% P, <0.003% S, and <0.008% Ca, and having 1.5-3.0 ratio of Ca/S or further contg. 1 or 2 kinds of 0.03-0.20% Cu, and <0.05% Mo are used as the steel materials for producing the electric resistance welded steel pipe for boilers and heat exchangers. The content of S is decreased as far as possible as this element induces groove-like corrosion in a weld zone in the case of forming the pipe by using such steel sheet and subjecting the same to electric resistance welding. The defect thereof is eliminated by adding Ca to the steel to form a stable sulfide therein. This steel pipe is usable as the steel pipe for boilers and heat exchangers in the as-welded state or after the part near the weld zone is subjected to the normalizing alone.
