Been calculated, 35CrMo steel carbon equivalent value Ceq = 0.72%. Thus, poor weldability of this material, welding tend to be larger when its hard, heat-affected zone hot cracking and cold cracking tendency will be greater, especially in the quenched state welding, heat affected zone will tend to cold cracking appeared very prominent, so should select the appropriate welding materials, welding method, based on reasonable, preheating before welding to a high temperature, stringent process control measures and appropriate temperature conditions between layers in order to achieve the goal of welding products purpose 本文来自上海双承模具钢材有限公司
