摘要
针对承压设备制造过程中低合金耐热钢与低合金高强钢(两焊件热处理制度不同)、低合金耐热钢与奥氏体不锈钢(第一焊件需热处理,第二焊件不需热处理)以及低合金耐热钢(两焊件热处理制度相同)之间采用堆焊隔离层分别进行不同金属材料焊件之间焊接的典型案例,通过制定合理的焊接工艺以及热处理制度成功解决了异种金属材料之间的焊接难题。结果表明,选用正确的隔离层焊材,在不同热处理制度下采用堆焊隔离层的方法焊接接头质量均得以保证,案例的成功应用为同类产品制定合理的焊接工艺提供了依据。
In view of the typical cases of welding between weldments of different metal materials by surfacing isolation layer between lowalloy heat-resistant steel and low-alloy high-strength steel(the two weldments have different heat treatment systems),low-alloy heat-resistant steel and austenitic stainless steel(the first weldment needs heat treatment,the second weldment does not need heat treatment),and low-alloy heat-resistant steel(the two weldments have the same heat treatment system)in the process of pressure equipment manufacturing,through the formulation of reasonable welding process and heat treatment system,the welding problems between dissimilar metal materials have been successfully solved.The results indicate that the quality of welded joints can be guaranteed by selecting the correct isolation layer welding material and using the method of overlaying the isolation layer under different heat treatment systems.The successful application of the case provides a basis for developing reasonable welding processes for similar products.
