Abstract:
The resistance seam welding method is used to conduct a test of the lap joint of 0.086 mm thickness stainless steel net and 1 mm thickness stainless steel support plate for space propellant tank.In order to solve the welding stainless steel problem of thickness ratio 10∶1 and weld width 1 ～ i.2 mm,a method of controlling the stainless steel sheet deformation and the stainless steel net tension,and checking the appearance quality,sealing property and internal quality of welded joint is adopted.The results demonstrate that the suitable welding parameters can avoid the poor weld joint shape in welding process and ensure a good sealing performance of weld joint,the stainless steel sheet deformation can be effectively controlled by using special fixture and postweld orthopaedic treatment,and a perfect stainless steel net performance can be achieved by adjusting the surface tension of stainless steel net in the weld process.
