镀铝钢的焊接性及焊接材料的研究

根据镀铝钢的组织性能的特点和镀铝钢焊接结构的生产要求，首先研制出满足镀铝钢结构要求的ＣｒＮｉＭｏ和ＣｒＭｏＲｅ合金系专用焊条，通过试验研究，提出了实际可行的焊接工用艺。

Study on Weldabilities of Steel with Aluminium Coating

The research works onCrNiMo alloy series welding electrode were carried out according to requirement of organic characters of steel with aluminium coating and constructure production. The tests of mechanical properties and oxygen resistence ability proved that the weldjoint characters could satisfy the construction requirment of steel with aluminium coating. The research works apply some technical conditions for enlarging the applyication of steel with aluminium coating.
