Abstract: A bimetal sleeve bearing has an axial seam that is laser welded so that both the soft inner layer and hard outer layer of the sleeve are continuous and homogeneous without internal or surface cracks. The seam edges are cut and abutted so as to form an axial groove in the inner surface of the outer layer. During the laser welding operation, fused material from the inner layer flows into the groove to form a crack-free lining for the bearing.

Abstract: The present invention is to provide a method for laser welding different kinds of metals by which at least two types of metal members having mutually different laser reflection factor, are put one upon another and welded when the metal members are irradiated with lasers emitted in the superposed direction, comprising a process to put the first metal member on the second metal member, wherein the first metal member has a first laser reflection factor and the second metal member has a second laser reflection factor which is lower than that of the aforementioned first laser reflection factor, and the first and the second metal member are put one upon another through a metal layer and when irradiated with lasers, the aforementioned metal layer is more difficult to melt than the aforementioned second metal member. The method of the present invention further comprises a process in which lasers are irradiated from the aforementioned first metal member side. According to the aforementioned method, laser output which is sufficiently high to melt the first metal member having a high laser reflection factor, is irradiated from the first metal member side, so that this laser output is excessively high to melt the second metal member. However, the aforementioned metal layer acts as if it inhibits the laser input to the second metal member. Accordingly, abrupt laser input into the second metal member can be avoided, and the occurrence of scatter of the metal can be prevented so that an excellent joint condition can be obtained.

Abstract: Methods of laser welding zinc coated galvalized steel are disclosed. In a method that relates to forming hem joints for motor vehicle body components a sheet of steel is provided with a plurality of V-shaped tabs. When a hem joint is formed the V-shaped tabs together with a surface of another sheet of steel form gas venting channels that provide an escape passage for gas vapors that are developed when the zinc coating is vaporized by laser welding. In another method of laser welding, one of the steel sheets has an axially extending wall that is V-shaped to provide a V-shaped groove and the wall has spaced gas vent holes.

Abstract: A surface of a linear magnetic bar is subjected to such high density energy as a fine beam of laser rays, electrons, ions, plasma or an electric current to change permeability of portions subjected to the high density energy so as to form graduations spaced uniformly. A magnetic sensor is used to detect variation in the permeability, thus measuring movement, speed or acceleration of the scale relative to the magnetic sensor. The scale may be formed on a movable portion of a machine, for example a piston rod of a die casting machine or an injection molding machine.
