摘要
Abstract
The weldability of these two kinds of steel was investigated thoroughly after study of physical property,chemical property,chemical composition and microstructure of 0Cr18Ni9Ti Austenitic stainless steel and 1J116 anti-corrosion soft magnetic alloy.A set of positioning tools and a set of heat dissipation tools were designed reasonably according to the analysis results of the outer shell structure of the cold air shutoff valve used in liquid rocket engine.The influence of welding parameters on microstructure and properties of welding seam rough is analyzed and feasible welding technology is drawn up by means of Schaeffier organization chart.The reasonable welding sequence was designed by analysis of stress and deformation mechanism.A number of products were successfully welded after the technology improvement,and all the products passed the inspection of the appearance and leak detection executed by Helium mass spectrometer.关键词
