  • Pinched Gas Flame Spot Heating for Removing Distortion on Welded Thin Steel Plate Structures

抄録

Gas flame spot heating is usually used for an object to remove the distortion of welded thin plate structures. However, in such a way, heating easily causes buckling distortion, and then it is not so easy to control of heating temperature and heating area, and to restrain its distortion.<BR>Now, in spite of the existing of these technical problems, it is widely owed to manual work, and automatic performance system is not still developed.<BR>In this investigation, it is studied that restraint of buckling distortion is automatically performed by using pinched gas flame heating process.<BR>Especially this report discribes effect of pinched gas flame heating on restraint of buckling distortion and its application techniques on rolling stock passenger car body assembly.<BR>The recsults were obtained as follows;<BR>1. Pinched gas flame can be made by cylindlical air flow around of propane-oxygen gas flame.<BR>2. Restraint of buckling distortion can be effectively performed by new pinched gas flame without other restraint apparatus. And its quantity is calculated by theoritical analysis.<BR>3. New developed automatic multi-pinched gas flame heating machine is effective and economical for restraint of buckling distortion on roof sheet of passenger car body.
