摘要

为消除定位焊缝对焊接质量的不利影响，提高U肋角焊缝的焊接质量，研制了组装焊接一体化专用设备，进行了U肋内侧角焊缝焊接试验，对比分析U肋内侧气体保护焊和埋弧焊的优缺点，重点解决了埋弧焊的焊剂下料不畅和焊缝成形不良问题，制定了U肋板单元免定位焊埋弧焊全熔透焊接工艺，通过足尺寸板单元焊接试验检验其可行性。结果表明：采用研制的专用设备和试验确定的焊接工艺可以实现免定位焊情况下的U肋角焊缝全熔透焊接，焊缝质量满足相关标准要求；控制U肋压制的尺寸偏差是实现免定位组装焊接的必要条件。

Abstract

In order to eliminate the adverse effects of tack welds on the welding quality and improve the welding quality of U-rib fillet welds, a special equipment integrating assembly and welding has been developed, and the welding tests of U-rib inner fillet welds have been carried out. The advantages and disadvantages of gas shielded welding and submerged arc welding for U-rib inner side have been compared and analyzed, and the problems of unsmooth flux blanking and poor weld formation for submerged arc welding have been emphatically solved. The full penetration welding process of U-ribbed plate element without tack welding is formulated, and its feasibility is verified by welding test of full size plate element. The results show that the full penetration welding of U-rib fillet weld without tack welding can be realized by using the special equipment developed and the welding process determined by the test, and the weld quality meets the requirements of relevant standards; it is necessary to control the size deviation of U rib pressing to realize positioning free assembly welding.
