技术领域
[0001] 本发明涉及一种特种金属的焊接方法，特别是一种铼合金薄板激光焊接方法。 背景技术
[0002] 铼为稀有难熔金属，具有高熔点（其熔点高达3180°C，仅次于钨的熔点3410°C )、 高强度、以及良好的塑性并且具有优异的机械稳定性，铼没有脆性临界转变温度在高温和急冷急热条件下均有很好的抗蠕变性能。由铼与其它金属可制得一系列耐高温、抗腐蚀、耐磨损的合金，如Re25-W曾是空间站核反应堆材料，后来发展到性能更好的Re30-W-Mo30合金；Re-Pt用作原子能反应堆结构材料，可抗100(TC高温下载热体的腐蚀，也可用于辐射防护罩；Re-Mo合金到3000°C仍具有高的机械强度，可用来制造超音速飞机及导弹的高温高强度部件及作隔热屏。特别是用于喷气式发动机涡轮叶片与火力发电机涡轮材料的镍基含铼超耐热合金的开发成功（含铼3%-7%，熔点高达31801：以上）并应用于战斗机及客机、火力发电机，超耐热合金已成为其最重要的应用领域。铼合金主要用于超高温和强热振工作环境，用于航空航天领域的耐高温结构件如火箭各类空间返回舱、卫星调姿发动机等的超耐热部件和次耐热部件。但是由于铼熔点很高，必须采用高能量密度的焊接方法才能保证具有足够的熔深和冶金结合。铼特别容易氧化，因此必须在严格的无氧气氛中进行焊接，才能防止铼材焊缝和热影响区的氧化，从而避免导致焊缝硬度升高及其脆化。目前，铼合金的连接技术采用高真空环境的电子束焊接方法，但真空电子束焊接必须在真空条件下进行，设备复杂，价格昂贵，成本较高，焊接前对接头的加工装配要求严格，被焊工件的尺寸和形状受到真空工作室大小的限制，而电子束易受杂散电磁场的干扰，影响焊接质量，产生 X射线，危害操作人员的健康和安全。
[0003] 与电子束焊接相比，激光焊接技术不需要真空室，被焊工件的体积不受真空室限制，不产生X射线，但是激光焊是在非真空条件下进行的，因此，如何提供简便的施工方法， 并通过工艺参数控制及防止焊缝氧化，获得高质量焊缝是铼合金激光焊实施的关键。
