A new welding method which can be used in the welding of metal and ceramic with gradient weld layer between them was investigated by means of self-propagating high-temperature synthesis ( SHS ) technique with the emphasis on the gradient weld preparation process .

本文将自蔓延高温合成（SHS）技术与焊接技术相结合，探索了用梯度材料作焊缝的陶瓷与金属焊接的新途径，着重研究了梯度 焊缝 的 制 备工艺。

Expressions for specifying the weld composition is proposed for the preparation of aluminum-coated steel electrodes .

并首次提出了 研制渗铝钢焊条时，设计 焊缝成分的公式。
