韶山1型电力机车转向架构架目前我厂系采用各梁加工后进行总组焊的工艺方法,总组焊时,在旁承座部位,其焊接部件较多,焊缝又集中,包括旁承座在内,另加枕枕法兰,闸缸座,焊角平均8毫米,焊缝总长达5740毫米。在此情况下是否会引起较大的焊接变形和梁体收缩?为此我们采用了各种不同的施焊顺序和焊接方法后,然后测定它对侧梁体、长拉杆座叉部收缩和变形的影响。
Shaoshan 1-type electric locomotive bogie frame At present, I plant using the beam after the total group of welding process, the total group of welding, in the side bearing seat, the welding parts more, the weld is concentrated, including the side bearing Seat, plus pillow pillow flange, brake cylinder seat, the average welding angle of 8 mm, the total weld length of 5740 mm. In this case will cause greater welding deformation and shrinkage of the beam? To this end we have adopted a variety of welding sequence and welding methods, and then measure it on the side beam body, long rod seat fork shrinkage and deformation Impact.
