The Q690D steel is the microalloying low-alloy high-strength steel with the yield strength of 690 MPa grade developed by Baotou Steel. It is with excellent low-temperature toughness, mainly used for engineering and mining machinery as well as the delivery of steel plate is in quenched and tempered condition. In order to grasp its basic weldability, the welding and postweld heat treatment technologies are formulated reasonably to make the performances of its welded joint meet the use requirements of industrial and mineral products. In the paper, the sensitivity of welding cold cracks, welding and postweld heat treatment technologies as well as comprehensive mechanical properites of its welded joint are with experimental study and assessment.

Q690D钢是包钢开发的屈服强度690 MPa级微合金化低合金高强钢,具有优良的低温韧性,主要用于工程和矿山机械,钢板调质状态供货。为了掌握该钢种的基本焊接性,合理制定焊接工艺及焊后热处理工艺,使Q690D钢焊接接头性能满足工矿产品的使用要求,文章对30 mm厚Q690D钢板的焊接冷裂纹敏感性、焊接工艺、焊后热处理工艺及焊接接头综合力学性能进行了试验研究及评定。

Q690D  /  焊接工艺  /  冷裂纹敏感性

The Q690D steel is the microalloying low-alloy high-strength steel with the yield strength of 690 MPa grade developed by Baotou Steel. It is with excellent low-temperature toughness, mainly used for engineering and mining machinery as well as the delivery of steel plate is in quenched and tempered condition. In order to grasp its basic weldability, the welding and postweld heat treatment technologies are formulated reasonably to make the performances of its welded joint meet the use requirements of industrial and mineral products. In the paper, the sensitivity of welding cold cracks, welding and postweld heat treatment technologies as well as comprehensive mechanical properites of its welded joint are with experimental study and assessment.
