  • Publication number: 20200406385
    Abstract: A base material is welded by a first welding method in a case where a welding parameter related to heat input to the base material is less than a first threshold value. The base material is welded by a second welding method in a case where the welding parameter is less than a second threshold value and is more than the first threshold value. The base material is welded by a third welding method in a case where the welding parameter is more than the second threshold value. By adjusting welding conditions regardless of the thickness of the base material, a welding method suitable for the thickness of the base material is determined to provide a welding with little spatter and no meltdown of the base material.

  • Patent number: 9399285
    Abstract: An industrial robot that can control the abrasion and damage of a bearing unit, and also control the deformation of an arm, even in the case of transferring a high-temperature transfer object in a vacuum. The industrial robot includes a bearing unit for supporting an arm at a joint section as a connection section between the arm and the main body. At the joint section, the arm has a first protrusion section protruding toward the main body, and meanwhile the main body has a first housing section in which a first hollow section for housing the first protrusion section is formed. The first protrusion section and the first housing section are formed of a material having higher thermal conductivity than the bearing unit has, and a semisolid thermally-conductive substance, having higher thermal conductivity than the bearing unit has, is placed in the first hollow section.
