Abstract: To solve the problems of conventional wire billet butt-welding such as high labor intensity, potential safety hazards, and low production efficiency, the disclosure provides a wire billet butt-welding apparatus and a wire billet butt-welding method. The wire billet butt-welding method comprises: S1: preparing a stock, S2: rotating a butt-welding stock receiver to a stock receiving position, and feeding a first coil of wire billet to a stock receiving rod of the butt-welding stock receiver; S3: welding the first coil of wire billet and the second coil of wire billet on a rotary plate at the butt-welding position end-to-head; S4: rotating the butt-welding stock receiver and the second coil of wire billet to the stock receiving position; S5: rotating the stock receiving rod to rotate to tighten the wire billet between the first coil of wire billet and the second coil of wire billet; and S6: repeating steps S3 to S5 to complete butt-welding operations on the 3rd to nth coils of wire billet sequentially. The solution implements semi-automated butt-welding operation; with provision of the rotary plate and the butt-welding stock receiver, enables automatic loading, automatic flipping, and automatic discharging, which reduces the manual workload, lowers the safety hazards, and improves the production efficiency.

Abstract: Proposed are the welding conditions under which welds are always stably formed such that the difference in hardness between flash-butt welds and rail base metal and the deflection in a bending test are in better ranges. A plurality of pieces of rail base metal are joined via welds formed by flash-butt welding, where the rail base metal has a chemical composition containing C: 0.60 to 1.20 mass%, Si: 0.10 to 1.50 mass%, Mn: 0.10 to 1.50 mass%, and Cr: 0.10 to 1.50 mass%, with the balance being Fe and inevitable impurities, and the flash-butt welding is performed with an amount of welding heat input of 1.50 × 10 5 kA 2 × sec or more and 4.50 × 10 5 kA 2 × sec or less.

Abstract: A pair of upper and lower pressure rollers (3, 4) is disposed so that their axes (15, 16) are tilted in a horizontal plane in respective directions opposite to each other with respect to a straight line perpendicular to a welding line of a joint portion J. The pressure rollers (3, 4) are positively driven by corresponding electric motors (63, 64) to thereby roll the joint portion. Thus, steps defined at the joint portion can be smoothed and a step gradient can be reduced to ensure a high degree of joint strength. The respective tilting directions of the axes (15, 16) of the pressure rollers (3, 4) are such that respective travel-directional portions (3A, 4A) of the pair of pressure rollers (3, 4) face in the horizontal plane toward the corresponding directions opposite to the extending directions of metal plates (5, 6) concerning a metal material with which the pressure rollers (3, 4) first come into contact. Thus, it is possible to prevent a step portion from being interfolded into the base material of the metal plates (5, 6). Thus, a stress concentration factor can be reduced and the steps S defined at the joint portion can be smoothed, thereby enhancing the quality of the joint portion.
