16MnDR钢埋弧焊材的研制

Development of welding consumables used by 16MnDR steel alloy

简要介绍了埋弧焊焊接方法的特点、产生背景、发展概况,以及国内自主研发的-46℃低温用16MnDR钢的生产工艺流程及其焊接性;总结了市场上典型的配套焊接材料H10Mn2/SJ101,H08MnMoA/HJ350,H10Mn2/SJ101的冲击性能,富裕量低且不稳定。针对此现状,安泰科技股份有限公司独立研制出配套焊材H08Mn2DR/SJ603W,该产品焊接工艺性能良好,其熔敷金属的机械性能优异,具有较高的低温冲击性能,在实际产品上的应用效果良好。

This paper briefly introduces features,backgrounds as well as overviews of development of submerged arc welding and production process,weldability of 16MnDR steel alloy which is used at-46 ℃.In addition,it also summaries impact properties of H10Mn2/SJ101,H08MnMoA/HJ350,H10Mn2/SJ101 which are universally used.The datas are a little low and unstable.According to the situation,ATM develops suited consumable H08Mn2DR/SJ603W which have good welding performance and excellent mechanical properties,being used in actual work widely and suitablely.
