33—1 如下图所示,把角钢型材以相等的焊脚宽度(s)焊在板上,若在该构件上加最大为P=5顿的拉力,求焊脚宽度(s)应为几毫米? 设容许剪切应力τa1=8 kg·f/mm~2,弯曲和应力集中忽略不计,两条焊缝的焊脚宽相等。 33—2 在无拘束或拘束极小的状态下焊接的对焊接头,请在指定的图中,定性地表示出(a)和(b)图中残余应力分布状况? 33-1 As shown in the figure below, the angle profiles are welded to the plate at the same fillet width (s). If a maximum tensile force of P = 5Ton is applied to the member, the weld leg width (s) Mm Allowable shear stress τa1 = 8 kg · f / mm ~ 2, bending and stress concentration is negligible, the two weld bead width equal. 33-2 Butt-welded joints that are welded without restraint or restraint shall be qualitatively represented in the designated figure by the residual stress distribution in (a) and (b).
