Abstract

A wire, tube or strip of plain carbon steel is coated with Al alloy, e.g. to form an automatic arc welding electrode, by traversing the material to be coated through a bath of molten Al-Si alloy having a protective surface layer of flux constituted by a fluoride or chloride of an alkali metal or Al and then, through a die which removes from the material surplus coating metal and flux, into a cooling tube containing a shielding gas, e.g. of A, H, CO2 or town gas, which prevents oxidation of the coating. The Al alloy in the bath contains 35-85% Al (all %s are by weight), 2-25% Si, the balance being one or more of the following in amounts up to the stated maximum proportions:-Mg 56%, Ce or other rare earth metal 15%, Cu 50%, Li 25%, Ca 5%, Na 5%, Zr 20%, Mn 20%, Fe 10%, Ti 5% and B 10%. On its way to the bath, the wire, tube or strip may be degreased by exposure to trichloroethylene vapour and be lightly abraded. The bath temperature may be 800 to 1,200 DEG C. The die may be immersed in the bath of coating metal.
