The invention discloses a trepanning operation method for a temporary auxiliary hole of a ship. The method comprises the following steps: step 1, drawing a trepanning track on a ship body wall plate needing trepanning; step 2, cutting an auxiliary pore plate according to the drawn track; step 3, forming a groove in the cutting track according to the drawing requirement; step 4, manufacturing a hinge tool; step 5, performing welding operation on the hinge tool; and step 6, cutting the reserved position of the auxiliary hole to complete the trepanning of the process hole. The method has the beneficial effects that: the trepanning operation method for a temporary auxiliary hole of a ship is convenient to operate and easy to operate, when the trepanning method is used for trepanning, the formed holes are attractive, later plugging is facilitated, and the later plugging difficulty is reduced.

    本发明公开了一种船舶临时工艺孔开孔操作方法,包括以下步骤:步骤一:在需要开孔的船体壁板上绘制开孔轨迹;步骤二:按照绘制的轨迹对工艺孔板进行切割;步骤三:在切割轨迹上按照图纸要求开设坡口;步骤四:制作铰链工装;步骤五:对铰链工装的焊接操作;步骤六:切割工艺孔的保留位置,完成工艺孔的开设。本发明的有益效果是,此船舶临时工艺孔开孔操作方法,便于操作,操作简单,运用此开孔操作方法进行开孔,开孔美观,且便于后期的封堵,降低了后期封堵的难度。
