我厂研制的CO_2焊接新工艺,几年来,经生产实践证明,效果良好。在此基础上,工人师傅和工程技术人员,又组成了三结合技改小组,在党的关怀和支持下,继续努力专研,经反复试验研究,突破了许多关键问题,终于又研制成功了靠轮跟踪自动焊接新工艺技术。并利用双丝头焊接,提高工作效率,保证了质量,进一 CO_2 welding new technology developed by our factory over the past few years, proved by the production practice, the effect is good. On this basis, the workers’ masters and engineers and technicians also formed a group of three combined with technological transformation. With the care and support of the party, they continued their efforts in specialized research. After repeated trial and research, they broke through many key issues and finally succeeded in developing Tracked by the wheel automatic welding new technology. And the use of double-head welding, improve work efficiency, to ensure the quality of one
