Title:
FORGE WELDING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/009875
Kind Code:
A1
Abstract:
[Problem] To provide a novel forge welding apparatus that makes it possible to perform solid-phase welding with a plastic flow at a welding interface, at relatively low temperature and in a short time. [Solution] The forge welding apparatus is characterized by comprising a support means that supports a plurality of members to be welded with welded portions thereof laid on one another, from the lower surface side of the welded portions, a pressurizing means that applies pressure from the upper surface side of the welded portions, a stroke control means that controls the interval between the support means and the pressurizing means, and a heating means that contacts the members to be welded directly or indirectly to increase the temperature of the welded portions to a predetermined temperature range, wherein the stroke control means controls the reduction ratio R(T0/T1), which is the ratio of the thickness T0 of the welded portions before welding and the thickness T1 of the welded portions after welding.
