The authors present in this paper the results of the study on the spot welding of 18/8 stainless steel sheets which contain a certain amount of Si, Ti, Mo and Cb raspectively The work carried out by the authors is outlined below. (1) The effect of variation in the electrode pressure, the duration of welding and the amount of electric energy consumed on the shearing strength of the welds between the plain 18/8 sheets were investigated. (2) The examination on the welds of the 18/8 sheets containing Si, Ti, Mo and Cb either alone or in combinations was made with respect to the hardness, shearing strength, tensile properties, macro-and microstructural characteristics, blow holes by means of X-ray and the corrosion-resistance. From the results obtained, the authors conclude that the mechanical properties of the spot are improved by the addition of Ti, Mo, Si, Si+Ti, or Si+Mo, and the corrosion-resisting property, especially against that of the inter-erystalline type which takes place around the spot, is considerably raised by the addition of a suitable amount of Ti, Ti+Si or Cb respectively.
