AN example of the stage which has been reached in arc-welding tech. nique is featured in an accompanying illustration. A erack in a cylinder block, which extended for 9f ins., is shown being repaired with the aid of Ferroweld electrodes, a prOduct of Lincoln Electric Co., Ltd., of Welwyn Garden City.
The crack was first veed out and then, by means. of a screw-type jack placed between the block and the chassis frame, the edges were brought ' together before welding, which was done in two runs and took under half
an hour. • It is claimed for Ferrowekl electrodes that they produce cast-iron welds of
greater tensile strength than the metal of the casting. They can be used at a low heat—about 80 amperes—which minimizes the possibility of either the weld or the work cracking. The usual hardening effect along the line of fusion is reduced and the weld, besides being strong and ductile, is easily machinable.
