我厂广大工人、干部和技术人员通过学习毛主席一系列重要指示,坚持以阶级斗争为纲,贯彻独立自主,自力更生方针,实行工人、干部、技术人员三结合,在较短时间内,克服了许多困难,终于试验成功了不加填充金属的非熔化极氩弧焊工艺。完成了壁厚0.5毫米、直径120毫米、长700毫米的不锈钢圆筒纵缝和环缝的焊接。经晶间腐蚀试验、24个大气压的气压试验和氦气检漏,质量完全合格。圆筒直径偏差在全长范围内不超过0.04毫米,保证了使用上的要求。
Through the study of Chairman Mao’s series of important instructions, the vast numbers of workers, cadres and technical personnel of our factory have persisted in using the combination of workers, cadres and technical personnel with the guideline of class struggle as the key link, implementing the principle of independence and self-reliance, and in a relatively short period of time, has overcome many Difficulties, and finally successfully tested without filling metal non-melting argon arc welding process. Completed the wall thickness of 0.5 mm, diameter 120 mm, length 700 mm stainless steel cylinder longitudinal seam and ring seam welding. After the intergranular corrosion test, 24 atmospheric pressure test and helium leak detection, the quality completely qualified. Cylinder diameter deviation in the full range of not more than 0.04 mm, to ensure the use of the requirements.
