The ultimate tensile strength and percentage elongation of solder joints of three alloy systems were tested.
Solder joints were formed using either an infrared soldering machine or gas-oxygen torch. Intact solder materials were used as controls.
There were no significant differences in percentage elongation among different treatment methods of the solders or among various solder materials. All intact solder materials possessed significantly higher ultimate tensile strength than the joints made with either method. For high-noble and noble alloy solders, there were no significant differences in ultimate tensile strength of joints made with either method. For base metal alloy solder, the ultimate tensile strength of joints made with the infrared technique was significantly higher than that made with the gas-oxygen torch technique.
The infrared technique can be used as an alternative to the gas-torch technique for soldering high-noble and noble alloys. It is superior to the gas-torch technique for soldering a cobalt-chromium alloy.
测试三种合金系统焊点的极限抗拉强度和伸长率。
使用红外焊接机或气氧焊炬形成焊点。完整的焊料材料用作对照。
焊料的不同处理方法之间或各种焊料材料之间的伸长率没有显著差异。所有完整的焊料材料的极限抗拉强度均显著高于用任何一种方法制成的焊点。对于高贵金属合金和贵金属合金焊料，用任何一种方法制成的焊点的极限抗拉强度没有显著差异。对于贱金属合金焊料，用红外技术制成的焊点的极限抗拉强度显著高于用气氧焊炬技术制成的焊点。
红外技术可作为气焊炬技术焊接高贵金属合金和贵金属合金的替代方法。在焊接钴铬合金方面，它优于气焊炬技术。
