摘　　要：为了能够在生产中提高耐蚀堆焊的效率和堆焊质量,采用国产焊带和焊剂,使用瑞典ESAB焊接设备进行堆焊试验。分别测定了电渣和埋弧堆焊的晶间腐蚀、侧弯、金相和硬度。宽带电渣和埋弧堆焊技术可以获得与304L性能相似的堆焊金属;带极埋弧堆焊时可以采用磁控装置来提高焊道质量。To improve the efficiency and quality of corrosion-resistant overlaying welding in production,the experiment on resurfacing welding was carried out using domestic strip and flux, applying welding equipment of ESAB.Intercrystalline corrosion,lateral bending, metallic phase and hardness of electro-slag strip cladding welding（ESW） and submerged arc cladding welding （SAW） were measured respectively.The technologies of ESW and SAW of broad band can acquire a deposited metal,whose property is similar to 304L stainless steel.The quality of weld pass can be improved by electric magnetic control for SAW.
