Abstract

PURPOSE: To prevent corrosion from occuring in the circumference of local welds by interposing corrosion preventive sealing rings and corrosion preventive sealing materials between the local weld zones of mutually opposite thin walled steel plates.
CONSTITUTION: Local weld zones 2A, 2B are formed opposite to each other to a pair of thin walled steel plates 1A, 1B. Corrosion preventive sealing ring materials 3AW3D are provided at suitable intervals between the local welds 2A, 2B. Also, corrosion preventive sealing materials 4A, 4B are interposed between the materials 3A and 3B, 3C and 3D. Both steel plates 1A, 1B are pressurized to each other and the weld zones 2A, 2B are welded to one piece, whereby a weld zone 5 is formed. Viscous composite bodies consisting of a polystyrene polymer contg. 20W60% fire powder of zinc are used for the corrosion preventive sealing ring materials and the materials prepd. by adding 1W20% ammonium nitrite, 1W20% fine powder of metallic zinc or 1W20% molybdate to natural rubber or synthetic rubber contg. no graphite powder are used for the corrosion preventive sealing materials.
