Description

对5A06铝合金MIG焊接接头的深冷强化处理方法
技术领域:
本发明属于对金属件深冷强化处理技术领域,具体涉及一种对5A06铝合金MIG焊接接头的深冷强化处理方法。
背景技术:
5A06铝合金具有较高的比强度、比模量、耐疲劳和耐腐蚀,还有良好的成型性能,因此在机械制造、航空、航天、造船、铁路、车辆制造以及兵器装备工业中均得到广泛地应用。在上述各行业应用中常常会遇到需要对铝合金零部件进行焊接,而在铝合金焊接接头处又往往因焊接时高热高温达350℃以上,使金属内部组织发生回复、再结晶、晶粒长大,使焊接接头处金属软化、机械性能下降,从而影响了使用要求,而且在腐蚀条件下,还会引起晶粒间腐蚀和开裂。为了解决上述问题,目前现有技术采用的焊接接头强化方法有三种:①焊后热处理。即对焊接后的工件进行热处理,这种方法可使接头处机械性能得到一定恢复,其强度一般可提高4.8%,但塑性下降了28.9%,往往只适用于小型焊接件,焊后还容易发生变形,同时进行热处理需要耗费大量能源,对环境也会造成一定的污染;②局部补强法。即加厚焊接接头的尺寸,使承载能力得到提高。这种方法增加了材料和能源的消耗,增加了工件的重量,还会在接头处产生残余应力,造成脱落,不牢固,往往只用于大型构件;③随焊碾压法。是指在焊接过程中对焊缝及近缝区实施碾压。该方法需增加碾压装置和劳动量,增大了成本,而且只适用于自动焊接。总之,上述三种现有技术均存在着一些缺点和应用的局限性。
发明内容:
本发明的目的是提供一种对5A06铝合金MIG焊接接头进行深冷强化处理方法,可以有效地克服现有技术存在的缺点。
本发明是这样实现的:是一种采用对金属件进行深冷强化处理的方法,其特征在于操作步骤是:①将经过MIG焊接的5A06铝合金件放入到由深冷处理系统控制下的深冷处理装置中;②以5℃~9℃/min的降温速率将深冷处理装置中的温度从室温下降到-150℃~-196℃;③保温2~6小时;④切断电源,关闭冷源,打开装置,让焊接件在空气中达到室温。
本发明的优点及积极效果有:①对5A06铝合金焊接接头经过深冷强化处理后,硬度可提高8.2%,强度可提高10.6%,而且内部组织晶粒度得到了细化和均匀化;②采用的冷源是液氮。液氮是制氧工业的副产品,来源广,容易运输和储存,化学性能稳定、无毒、无污染,不腐蚀工件,价格低廉,不仅成本低,而且有利于环保;③操作简单。
具体实施方式:
1.以经过自动MIG焊接的5A06铝合金工件为例,操作步骤为下:
①将经过自动MIG焊接过的5A06铝合金焊接件放入到以液氮为冷源并由计算机控制的DWS-2188深冷强化处理装置中;
②以6℃/min的降温速率将深冷处理装置中的温度从室温下降到-196℃;
③在-196℃保温6小时;
④切断电源,关闭液氮,打开装置,让焊接件在空气中达到室温。
2.以经过手工MIG焊接的5A06铝合金工件为例,操作步骤为下:
①将经过手工MIG焊接过的5A06铝合金焊接件放入到以液氮为冷源并由计算机控制的DWS-2188深冷强化处理装置中;
②以6℃/min的降温速率将深冷处理装置中的温度从室温下降到-180℃;
③在-180℃保温5小时;
④切断电源,关闭液氮,打开装置,让焊接件在空气中达到室温。
