摘要
为了提高焊接工作效率,降低焊接成本,减轻焊工劳动强度,通过两种规格焊条焊接V型坡口对接平焊试件对比,论证了选用φ4.0 mm焊条打底焊,较采用φ3.2mm焊条打底焊更为比较合理可行。
In order to improve the welding efficiency and reduce welding costs and the labor intensity of welders,experiments in butt welding of V groove are done to compare two kinds of electrodes with different specifications,the result of which shows that the use of welding rods of 4.0 mm is more reasonable and feasible than that of rods of 3.2 mm.
