摘要
对焊接头主要外形尺寸进行了测量，经统计分析：焊趾角、焊缝宽、焊缝加厚高与接头错位符合正态分布，焊趾曲率半径符合对数正态分布，焊缝加厚高与接头错位亦符合威布尔分布。依此对焊接头焊趾处应力集中系数Ｋｔ进行了计算。
The major shape measurements of butt welded joints are measured It is obtained by statistical analvsis taht the statistical distribution of weld toe angle,weld width,weld reinforce-ment and weld misalignment is nonnal and that of radius at the weld toe is logarithm nonnal.It is also found that the distribution of weld reinforeement and misalignment is Weibull.The stress concentration factor Kt at the weld toe is calculated.
