    摘要: There is provided a method of making a welded can body having a mash seam weld which includes a heat affected zone extending continuously in the longitudinal direction thereof and is formed with no pitting. The weld is formed by mash seam welding a lapped portion of a can body preform made of a surface treated steel sheet while allowing an alternating current to flow through the lapped portion via a water-cooled elongated electrode and a water-cooled rotary electrode. The alternating current has a crest factor satisfying an expression 1.5.ltoreq.Ip/Ie.ltoreq.2.0, where Ie and Ip designate an effective value and a peak value, respectively, of the alternating current.

    摘要: A method of preparing hollow metallic bodies by contacting flat droplets of a molten metal with a liquid capable of readily gasifying at a temperature lower than the melting point of said metal. Upon contact the liquid gasifies under the flat droplets and the gas pushes up the center of the flat droplets. The edges of the droplets fall because the vapor near the edges goes around the edges. As the middle of the droplets rises the surface tension of the droplets brings the edges together thereby forming the hollow metallic body.
