文中分析了薄板脉冲熔化极气体保护焊(P-GMAW)全熔透过程的成形规律,从熔融金属体积量出发,提出了可以反映熔透的正面熔池及焊缝特征参量。
Both monotonic axial compressive and axially loaded cyclic tests have been carried out on the steel box brace used in New CCTV Building to investigate the effect of assembling welds including full penetration and partial penetration on the structural behavior of the brace.
为考察全熔透和部分熔透两种组装焊缝形式对箱形截面钢支撑受力性能的影响,本文对中央电视台新台址建设工程中的箱形截面支撑进行了单调受压、轴向反复拉压试验;同时,采用ABAQUS有限元软件实现了对部分熔透试件未熔透处的接触模拟和滞回性能模拟。
At present in China,one side full penetration welding of heavy plate are rarely designed and nealy no metal construction manufacture can satisfy this request without any defact after welding UT check.
目前国内设计很少应用大量的中、厚钢板单面焊全熔透焊缝,也几乎没有能够满足此种焊缝质量要求的金属结构件制作厂家,多数厂家即使是压力容器专业制造厂,在焊接此类焊缝时,也会存在不同程度的焊缝根部未熔合或未焊透,通过采取新型焊接工艺,反复试验,不断改进,最终保证了此类焊缝UT探伤时焊缝有效深度≥板厚,UT探伤一次合格率达90%以上,有效地保证了此类焊缝的焊接质量,同时也大大提高了生产效率。
