为了提高船体建造过程中焊接的机械化程度,我厂于1971年底组成三结合试验小组,开始研制全位置自动焊接工艺及设备,1972年底工艺试验和样机制作基本完成;1973年上半年又作了一些改进和设备配套,现已在实际生产中开始试用。这种焊接工艺,主要适用于船体分段和总段合拢过程中的垂直位置以及带有曲线形状的外板对接缝,目前主要用于垂直立向焊缝。其特点为: 1.采用细丝CO_2气体保护焊接法,能进行各种位置的焊接; In order to improve the degree of mechanization of the welding during the construction of the hull, our factory formed a three-in-one test group at the end of 1971 and began to develop all-position automatic welding process and equipment. At the end of 1972, process tests and prototypes were basically completed. In the first half of 1973, Improvement and equipment support, is now in the actual production trial. This welding process is mainly applied to the vertical position of the hull section and the total section closing process as well as the outer panel butt joint with the curved shape, which is mainly used for vertical upright welds at present. Its features are: 1. Adopt filament CO_2 gas shielded welding method, capable of welding in various positions;
