| Abstract: | According to heavy-duty rail welding of containers at the port of Shantou,this paper studied high-carbon high-strength alloy-rail welding by using regular manual electric arc welding technology.The research indicated that using multi-layer and multi-channel welding technology of pre-heating,post-heating and show-cooling could promote welding-joint quality to reach the requirement for rail use-quality in engineering design.Acceptance quality level of the welding reaches one hundred percent once only. |
