<正>SYSWELD was used to simulate in-service welding process of gas pipeline of X70 pipeline steel.Welding thermal cycle,stress and deformation of in-service wel
Three kinds of mathematical models representing welding heat sources are presented. Among them, Gaussian model and double ellipsoidal model are used to analyze
In this paper, the brazing mechanism of LY12 aluminum alloy at middle range temperature was presented. The CsF-AlF3 non-corrosive flux was utilized to remove th
Dynamics in partial transient liquid phase bonding (PTLP bonding) of Si3N4 ceramic with Ti/Cu/Ti multi-interlayer was systematically studied through micro-analy
An axisymmetric finite element model is developed to simulate the temperature field of resistant spot welding according to the process characters of nugget form
