    • A method and apparatus for permanently joining two or more metallic vehicle frame components using magnetic impulse welding techniques is disclosed. In a first embodiment, an overlap joint is formed by the joinder of two individual open channel side rail sections to form a portion of a vehicle frame side rail. The first side rail section is initially formed slightly smaller in size than the second side rail section so that it may be disposed telescopically therein with clearance. An electromagnetic coil is provided for generating a magnetic field which causes the side rail sections to move toward one another at a high velocity. The high velocity impact and the large pressures cause the two side rail sections to weld or molecularly bond. Alternatively, a bracket can be joined to a side rail section in a similar manner. In a second embodiment, a pair of closed channel structural members are formed using hydroforming techniques. The end portions of two hydroformed structural members are then disposed concentrically within an electromagnetic coil. When energized, the electromagnetic coil causes the end portions to move toward one another so as to weld or molecularly bond.
    • 公开了一种使用磁脉冲焊接技术永久地连接两个或更多个金属车架部件的方法和装置。 在第一实施例中,通过两个单独的开放通道侧轨道部分的接合形成重叠接头,以形成车辆框架侧轨道的一部分。 第一侧轨部分的初始形状稍小于第二侧轨部分的尺寸,使得其可以以间隙可伸缩地设置。 提供电磁线圈,用于产生使得侧轨部分以高速度彼此移动的磁场。 高速冲击和大压力导致两个侧轨部分焊接或分子结合。 或者,托架可以以类似的方式接合到侧轨部分。 在第二实施例中,使用液压成形技术形成一对闭合通道结构构件。 然后将两个液压成形结构构件的端部同心地设置在电磁线圈内。 当通电时,电磁线圈使得端部彼此移动以便焊接或分子结合。

    • The invention is a new method for fabricating welded structural frames (1, 2, 3) for grating assemblies used in pellet and sinter machines and other material processing systems which require grating assemblies for heating, cooling, indurating, burning and transporting products through heating and cooling furnace systems to minimize the cracking and warping of grating assemblies normally associated with castings. Chrome-molybdenum metallurgical and dimensionally specified hot rolled profile structures are prepared and suitably reinforced with flat plate chrome-molybdenum alloy steel. The frame is manufactured according to a unique template in order to achieve dimensional accuracy and trueness. Special welding procedures have been developed for achieving reliable welded joints. The frame is heat treated to relieve stresses caused by welding of the frame. Subsequently, the frame is machined to achieve squareness and perpendicularity. Finally the frame is spray painted to protect the structure in storage and during transport.
