本文研究了T形角焊缝在外约束条件下的变形。我们考虑了两种类型的约束，如图1所示。母板的挠度近似表示为方程。(1)（对于情况1）或eq. (7)（对于情况2），其中δ0是焊缝中心处的角度变化，矩形坐标如图2或图8所示。如图3所示，δ0小于自由接头中的角度变化δj。（c. F. 1号和7号标本）。用能量法得到了δ0与δj的关系式，并由方程给出。(5)其中C是取决于外部约束条件的常数。(see当量(6)对于情况1和eq. (9)例2）。绘制了约束系数C的各种实验结果。(see图9和表2）。从报告2和6的结果中，我们可以获得给定焊接条件和外部约束的T形角焊缝接头的变形。
In this paper we studied on the distortion of tee-fillet welded joint under external constraint. We considered two types of constraint such as shown in Fig. 1. Deflection of mother plate is approximately represented by eq. (1) (for Case 1) or eq. (7) (for Case 2), where δ0 is angular change at the center of weld line and rectangular co-ordinates are taken as shown in Fig. 2 or Fig. 8. δ0 is smaller than the angular change in free joint, δj, as shown in Fig. 3. (c. f. specimen No. 1 and No. 7). Relation between δ0 and δj is obtained by energy method, and it is given by eq. (5), where C is a constant depending on the conditions of external constraint. (see eq. (6) for Case 1 and eq. (9) for Case 2.) Various experimental results were plotted for the coefficient of constraint C. (see Fig. 9 and Table 2).From the results of Report 2 and 6, we can obtain the distortion of tee-fillet welded joint for the given welding conditions and external constraint.
