在党的正确領导下,我国钢铁工业和机械制造工业得到了空前的发展,有很多产品已經达到国际水平、并且正在向着高大精尖的方向迈进。为联接金屬最主要方法中所不可缺少的焊接設备也是正向着同一方向飞跃发展。最近我厂先后試制成功的自动化預热閃光焊接的MR-500钢軌对接焊机、航空工业用NJ-600冲击波轻金属点焊机、无綫电及其他精小零件用PD-3点焊机、重型机械制造用HG-1000万能电渣焊机、高生产率的
Under the correct leadership of the party, China’s iron and steel industry and machinery manufacturing industry have enjoyed unprecedented growth. Many products have reached the international level and are moving in the direction of being highly sophisticated. The most important method for joining metal welding equipment is also indispensable to the same direction leap forward development. Recently, our factory has successively trial-produced the pre-fired automatic preheating flash welding MR-500 rail butt welding machine, the aviation industry NJ-600 shock wave light metal spot welding machine, PD-3 spot welding machine for radio and other small parts, HG-1000 universal electroslag welder for heavy machinery manufacturing, high productivity
