21世纪焊接材料研究和发展的趋势

The Trends of R.&.D.of Welding Consumables in 21st Century

在预测21世纪焊接材料的发展趋势后,提出21世纪焊接材料的研究方向为:进一步深入研究焊接物理冶金和化学冶金;加强焊接材料配方设计从经验上升到理论的研究;新工艺sol—gel法及分子筛在焊接材料上应用的研究,最后提出对我国焊接材料研究和进一步发展的建议。

This paper introduces the development trends of welding consumables in 21-st century and then the research directions are proposed,they are:further deep researches on welding physi-co-metallurgy and chemico-metallurgy;researches on the formulation design of welding consumables from art to theory; researches on applying new technology and research results such as sol-gel process,molecular sieves (zeolites) to welding consum-ables.Finally,some suggestions are given for R.& D.of welding consumables in China.
