摘　　要：滑道是导管架下水驳船的作业关键结构,导管架在滑道上滑移到艉部通过摇臂翻转进行下水作业。H542导管架下水驳船的滑道全长145m,但其精度要求确是毫米级的,为同时保证其结构强度和精度,其制作焊接要进行周密的策划。文章介绍了一种导管架下水驳船滑道的制作焊接工艺,该工艺可实现滑道的高精度制作,为将来导管架下水驳船的作业提供保障。Skid beam is the key structure of jacket launch barge, the jacket slides to ship stern on skid beam and carries out launching by tilt beam rotation. The whole length of skid beam of H542 launch barge is 145 m, but structure accuracy is millimeter-level, construction and welding to be specially considered for guarantee the structure strength and accuracy requirements. This paper elaborates a construction and welding procedure which can guarantee the accuracy to ensure future operation.

关 键 词：下水驳船 滑道 精度 焊接
