随着科学技术的发展,薄壁焊接件日益增多,其壁厚日益减小,结构日益复杂,而且对焊缝的要求日益提高。为得到优质的焊接接头,必须对焊接设备、焊接工艺装备和焊接工艺参数,进行全面系统的研究。本文仅就1963年以来0.5毫米以下1Crl8Ni9Ti奥氏体不锈钢薄钣的氩弧焊的研究进行初步总结。 With the development of science and technology, the number of thin-walled welded parts is increasing day by day. Its wall thickness is decreasing day by day, the structure is increasingly complicated, and the requirements for the weld seam are increasing day by day. In order to obtain high-quality welded joints, we must conduct a comprehensive and systematic study of welding equipment, welding process equipment and welding process parameters. This article only preliminary studies on the welding of 1Crl8Ni9Ti austenitic stainless steel sheet metal below 0.5mm since 1963.
