摘要:
There is here provided butt-welded cans made of steel plates having a carbon concentration of 0.02 to 0.09% by weight, the aforesaid butt-welded cans being characterized in that a coating film for preventing the adhesion of melted metal particles is applied to at least the inner surface of the weld portion and its vicinity of each can, and a carbon concentration index I of the weld portion satisfies the formula (1)I=(Iw/Ic).times.10.sup.3 .ltoreq.15 (1)wherein Iw is a K.alpha. X ray intensity, of carbon in the weld portion, measured by the EPMA method, andIc is a K.alpha. X ray intensity, of carbon in graphite, measured by the EPMA method.
