| Abstract: | This paper has researched the process of one side welding of ceramic backing WQT-1, forming quality of back weld, chemical composition of weld, and mechanical properties of joints with CO_2 Gas Shielded Welding, X-ray inspection, tensile, bend and impact test. The results show that the sintering backing WQT-1 has good resistante of absorbing moisture, the drying process is not needed before welding; The range of rational standard of welding is relatively wide, it is convenient for selecting the welding standard; The appearance of back weld is very good, welding quality is stable and re liable; and properties of joins is excellent. |
