摘要
综述了近年来镁合金在钨极氩弧焊、搅拌摩擦焊、电子束焊及电阻点焊方面的国内外研究现状。TIG焊是镁合金最常用的焊接方法,但能量密度不高,熔深较浅,热影响区较宽;而活性TIG焊可以改善镁合金TIG焊熔深浅的缺点,是镁合金电弧焊未来的发展方向;搅拌摩擦焊作为固相连接技术应用于镁合金具有独特的优势,是镁合金焊接的一个比较理想的方法。
The research status of tungsten inert gas welding,friction stir welding,electron beam welding and resistance spot welding of magnesium alloy in China and abroad was summarized.TIG welding is a most common welding technology,but with lower energy density,shallow penetration and wide heat affected zone.Active-TIG welding can improve the shallow penetration disadvantages of TIG welding,which is a potential arc welding method of magnesium alloy in the future.As a solid phase welding technology,friction stir welding has unique advantages and is a more ideal method for the welding of magnesium alloy.
