制造全金属铁路敞车时,劳动量最大的工序之一是连接侧墙和端墙的角焊缝的焊接。一个敞车上有8条这样的焊缝,它们每条长近2米。焊脚不小于7毫米。由于焊缝的一半位于敞车的内部,因此使焊工的劳动条件大大地恶化。 One of the most labor-intensive processes for making all-metal railway gondolas is the fillet weld, which joins the side walls to the end walls. There are eight such welds in a gondola, each of which is nearly 2 meters in length. Solder leg not less than 7 mm. Half of the weld seam is located inside the gondola and therefore greatly deteriorates the working conditions of the welder.
