• Effect of Welding Conditions on the Transverse Shrinkage Distortion of Bead-on Plates : Shrinkage distortion in welded joints (Report 1)

抄録

As the most fundamental case of shrinkage distortion in welded joints, we have studied on the transverse shrinkage distortion of bead-on plates. Characteristics of transverse shrinkage distortion are shown in Fig. 4. Both angular distortion and shrinkage produce near the weld bead, and the distorted portion correspondes to the range heated above 150∿200℃ when welding (see Fig. 5). Comparing the results of Fig 1,2 and 3,we know the shrinkage distortion appears approximately uniform except for the ends of weld. To analyse the deformation of bead-on plate we assumed that shrinkage forces and shrinkage moments act as shown in Fig. 6,and inherent strain, the cause of distortion, distribute as shown in Fig. 7. Transverse shrinkage and angular change are then represented by eqs. (1) and (2). Fig. 8 shows the characteristics of these equations. Simple formulas of transverse shrinkage and angular change are obtained from Fig. 8 and the results of our former study (see Reference 1), and they are eqs. (6) and (7). Experimental results are shown in Fig. 9 and 10.
