The purpose of the present paper is to examine the thermal cycles and discuss the influences of thermal cycles upon structure and tensile strength at the butt welding parts of thin stainless plate (SUS 304) by C0_2 gas laser. However, there are few researches hitherto which deal with those problems. So, in this paper the authors have meas-ured temperature, structure at the butt welding parts by using of PR thermocouple , and electron probe microanalyser, Moreover, the measured results of temperature were compared with the experimental results in the case of bead on plate method and the theoretically calculated results. The conclusions are as follows, (1) By this re-search, the thermal cycles of the welding parts at each welding velocity were shown and the influences of those cycles upon structure and tensile strength of the welding part could be clarified, (2) The experimental values, of the temperature at the butt welding parts are higher than those of the case of bead on plate method and theoretical calculation. (3) The practical formula describing the tempera-ture at the butt welding parts is able to derived.
