近年来,有的国家在建造万吨级的船舶时,对船体总段对接垂直焊缝,采用效率较高的电渣焊或气电焊等新工艺。国内某些厂对中薄板垂直气电焊曾作了大量研究与应用,但还未成功地用于万吨级船舶总段对接垂直焊缝的焊接。遵照毛主席关于“中国人民有志气,有能力,一定要在不远的将来,赶上和超过世界先进水平””的教导,我厂在党委的正确领导下,成立了以工人为主体的试验小组,并在上海交通大学及某研究所的大力协助与 In recent years, some countries in the construction of 10,000-ton ships, the hull of the total docking vertical weld, the use of more efficient electroslag welding or gas welding and other new technology. Some domestic plants on the vertical gas-sheet welding has made a lot of research and application, but has not been successfully used for the 10,000-ton ship vertical docking butt welding. Following Chairman Mao’s teachings on “Chinese people have ambition and ability, we must catch up with and surpass advanced world levels in the near future”, our factory set up a pilot with workers as the main body under the correct leadership of the Party committees Team, and a strong support in Shanghai Jiaotong University and a research institute
