Title: Harumichi Hino: Innovator in Welding Technology
Introduction
Harumichi Hino is a notable inventor based in Shizuoka-Ken, Japan. He has made significant contributions to the field of welding technology, particularly in the development of methods for joining aluminum alloys. With a total of 3 patents to his name, Hino's work has advanced the capabilities of friction and arc welding processes.
Latest Patents
One of Hino's latest patents focuses on the friction welding of aluminum alloy hollow members. This innovation involves controlling the root shape of a flash formed in the friction-welded joint by introducing an upset delay time between the friction and upset steps. By managing the upset displacement speed, Hino's method achieves a friction-welded joint with tensile and fatigue strengths comparable to those of traditional TIG or MIG welded joints. Typically, the upset delay time ranges from 0.4 to 0.8 seconds, and the upset displacement speed is between 5.0 to 70.0 mm/sec, resulting in a flash with a root radius of 0.5 mm or more and a root angle of 75 degrees or less.
Another significant patent pertains to an arc welding method for aluminum members. This method reduces the quantity of input energy when welding at speeds of 2-7 minutes, allowing for the formation of welded joints that are free from deformation or strains. The high thermal conductivity of aluminum promotes sufficient penetration, which is further enhanced by jagging the groove face. Hino's approach stabilizes the heat balance between aluminum members with differing heat capacities by using a jig with a larger heat capacity in contact with the member that has a smaller heat capacity.
