چکیده
Welding technology of cast steel G18CrMo4+QT with structural S355J2+N is a welding dissimilar steels. The problem iron the phenomenon hardening structure due to presence unreleased martensite, which results in lower toughness and formation cold cracks. On other hand, S355J2+N, depending on thickness material, also prone appearance In order prevent cracks eliminate residuals stresses, it necessary perform preheating heat treatment after welding. paper presents technologies subsequent joint S355J2 + N presentation test performed 12 mm thick welded sample, V preparation joint, by MAG process PA position.

متن کاملCooling rate optimization of as-cast consciously cast steel
Abstract: A combination of a finite element method (FEM) algorithm with ANSYS codes and post image processing of NDT ultrasonic images along with laboratory cooling experiments and microstructural analysis provide a guideline to determine the optimum cooling rate for any grade of steel in which the highest productivity can be achieved without any degradation of the cast steel products. The sugg...
