Abstract: A butt welding apparatus and a butt welding method where end faces of at least one plate member to be welded are butted to each other to form a butt portion, and butt welding can be performed on respective plate members which have various thickness sizes on both side portions of the butt portion with electric resistance heat by a pair of electrode members which are common to the respective plate members. At least one electrode member (1) is provided on an outer face thereof with a convex portion (1A) which gradually retreats from one plate member (31) of two plate members (31, 32) as it extends from an intermediate portion, in a thickness direction, of the one electrode member (1) along the one plate member (31).

Abstract: A reduction of the unevenness of a temperature increase at the end of heating work can be achieved without specific equipment, and with securing the shortening of the working time, which is an advantage of a bulk heating. When a region to be heated of an article made of a thin sheet is heated inductively so that the whole region thereof reaches a temperature equal to or more than a target temperature using an inductive portion of a heating inductor, to which a high-frequency current is applied by a power supply device, by stopping or reducing temporarily the power application of the high-frequency current to the heating inductor during the temperature increase, a temperature difference in the region to be heated is reduced so that the unevenness of the temperature increase at the end of the heating work is reduced by the step of reducing the temperature difference.

Abstract: A heat treatment operation can be executed, suppressing a wave-shaped deformation at a non heat-treatment region of an article to be heat treated. To an elongated-shaped article to be heat treated to which a raised portion extending in the longitudinal direction is formed, a hardening region, as a heat-treated region defined to extend in a longitudinal direction at a part of the raised portion, and a non-hardening region, as a non-heat-treated region defined to extend in the longitudinal direction at flange portion, and other parts of the raised portion are arranged side by side in a width direction orthogonal to the longitudinal direction. The flange portion is clamped by a first and a second clamp, arranged in the longitudinal direction, and one first clamp is a tight clamp for holding fixedly the flange portion and a plurality of second clamps are loose clamps for clamping loosely the flange portion, allowing the article to be heat treated to be convex on the side of the heated hardening region.

Abstract: A butt welding apparatus, a butt welding method, and a product manufactured by the butt welding method involves two electrode rollers disposed on both the front and back sides of a thick sheet member and a thin sheet member whose end surfaces are butted. The electrode rollers bridge across the sheet members and are composed of small diameter portions on the side of the thick sheet member and large diameter portions on the side of the thin sheet member. The small diameter portions come into contact with and press the thick sheet member before the large diameter portions come into contact with the thin sheet member. Thus, the end surface of the thick sheet member swells and deforms toward the thin sheet member and reliably comes into contact with the end surface of the thin sheet member, and power is applied between the end surfaces, even if not polished.

Abstract: A method and an apparatus for machining a mold material to produce a mold. By casting based on a cast mold model (15), a mold material (20) is produced in a form having a work margin. Thereafter, a shape of the mold material (20) is measured by a measuring device (16), and measurement data and an envelope model (M2) generated based on the measurement data are stored in a storage unit (12A) of a computer (12). Thereafter, a mold model (M1) based on mold design data and an envelope model (M2) are displayed on a display unit (12C), and the envelope model (M2) is linearly moved in direction of three axes X, Y and Z orthogonal to one another respectively and rotated around the three axes to bring a product forming plane (M2B) of the envelope model (M2) into close proximity of a product forming plane (M1B) of the mold model (M1).
