    • A flash and upset material formed in a flash welding operation can be removed by a machining of the flash and upset material for a short time after the welding operation by providing a workpiece clamping function by a main clamp and providing a welding current feeding function by an electrode table. The main clamp is heavy whereas the electrode table is light so as to be easily movable, whereby the electrode table in the light weight can be backwardly shifted for a short time after the welding operation and a space for inserting a tool holder equipping with a tool for machining a flash and upset material, is formed near the welded line. Since the flash and upset material can be machined during the time maintaining the softness of the flash and upset material at relatively high temperature for a short time, the machining can be attained by only pair of tools.
    • 在闪光焊接操作中形成的闪光和镦粗材料可以通过在焊接操作之后的短时间内对闪光和镦锻材料进行加工来消除,通过主夹具提供工件夹紧功能,并通过主焊机提供焊接电流馈送功能 电极台。 主夹具重,而电极台轻便易于移动,由此在焊接操作之后,重量轻的电极台可以在短时间内向后移动,并且用于插入具有工具的工具架的空间 用于加工闪光和镦粗材料,在焊接线附近形成。 由于闪光和镦粗材料可以在短时间内保持闪光和镦粗材料在较高温度下的柔软度的时间内被加工,所以可以仅通过一对工具来实现加工。

    • A molded article of plastic having on its surface a cured film of a coating material comprising at least 30% by weight of at least one polyfunctional compound selected from the group consisting of poly-methacryloyloxy compounds having a molecular weight of 250 to 800 and containing at least three methacryloyloxy groups in the molecule and poly-acryloyloxy compounds having a molecular weight of 250 to 800 and containing at least three acryloyloxy groups in the molecule, and optionally 0.01 to 5% by weight of a fluorine-containing surfactant and 0.01 to 5% by weight of a carbonyl compound as photosensitizer has improved surface characteristics, particularly a high surface hardness, a high surface smoothness, high heat resistance, high abrasion resistance and a minimized optical distortion. Said molded article of plastic having improved surface characteristics can be prepared by coating the molded substrate of plastic with said coating material to a thickness of 1 to 50.mu. and then subjecting the coated article to a light of 2,000 to 8,000 A in an inert atmosphere to cure the coating material.
