ABSTRACT:
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.
