摘要
介绍某工程中大型铸钢节点与无缝钢管现场焊接的关键技术。成功解决了工程中铸钢节点与无缝钢管节点形式的选取、铸钢节点与无缝钢管V形坡口的设计原则、焊接工艺、焊材焊接机具选择、焊接环境、焊接参数、焊前预热措施、焊接质量控制、焊接变形控制、焊接防护措施以及焊后处理等技术问题。
The paper introduces the key technology of welding cast-steel joint to the seamless steel pipe in a project. It is a successful case for similar project and the contents include choice of the welding joints of large cast- steel and seamless steel pipe, design principle of V-shape groove of the joints, welding process specification, selection of welding machine and welding material and welding key points, such as welding environment, welding parameters, welding warming-up,control of deformation, and welding protection, treatment measures after welding, etc.
