Latest Patents

Kouji Sato holds 1 patent for a friction stir welding method. This method is designed to decrease the friction force during the welding process. It involves using a welding tool, made from a harder material than the workpieces, which is rotated and pressed into the weld zone. A power supply device allows current to flow between the welding tool and the workpieces, causing resistance heating of the welding tool. This combined use of resistance heating effectively reduces the friction force. Additionally, a conductive ceramic is preferably coated on the surfaces of the welding tool to facilitate this resistance heating.
