The reasons for different mode of welding residual stress distribution and influence of flame curving on steel structure are discussed.
简要阐明了造成不同焊缝应力分布的原因及火工校弯成形工艺对构件残余应力分布的影响。
Cold-formed steel cross section on the residual stress distribution is curved, and hot rolling steel or steel section on welding residual stress distribution is a thin film type.
冷弯薄壁型钢截面上的残余应力分布是弯曲型的,而热扎型钢或焊接型钢截面上残余应力分布是薄膜型。
In this paper the effect of strength matching of welded joint on welding residual stress distribution in plate welded joints was studied by an thermal elastoplastic finite element method.
采用热弹塑性有限元方法,对平板对接接头中焊缝金属强度组配对焊接残余应力分布的影响进行了研究。结果表明,对于高组配接头,纵向残余应力的峰值接近焊缝金属的屈服极限,出现在焊缝中心。
