    摘要： Surface treated steel strip is prepared for electric resistance welding by forming an Fe-Ni alloy layer on the steel, forming a second layer of Sn and then subjecting the strip to an electrolytic chromate treatment. The first layer has a wt. ratio of Ni/(Fe+Ni) of 0.2-0.5 and a thickness of 10-5000 angstroms. The second layer has a coating weight of 0.1-1g/m2 of Sn. The process is characterised in that the electrolytic chromate treatment is carried out in a bath containing an amount of a chromate compound to give 10-100g/l of CrO3 and a weight ratio of H2SO4/CrO3 in the2range 3/1000 and 1/1000.
