Description

一种3003防锈铝合金的钎焊工艺
技术领域
本发明涉及一种钎焊工艺，尤其是一种3003防锈铝合金的钎焊工艺。
背景技术
3003防锈铝合金是一种用途最为广泛的防锈铝，在退火状态有很高的塑性，在半冷作硬化时塑性尚好，冷作硬化时塑性低，耐腐蚀好，焊接性良好，可切削性能不良。主要用于要求高的可塑性和良好的焊接性的零件。但由于铝合金低的熔化温度，故其钎焊性较差，致使其应用受到局限。
发明内容
本发明旨在解决上述问题，提供了一种3003防锈铝合金的钎焊工艺，重点是选择4343铝硅合金作为焊接材料进行焊接，其采用的技术方案如下：
一种3003防锈铝合金的钎焊工艺，其钎焊工艺的步骤依次为：
a)选择钎料：钎料选用4343铝硅合金，具有熔点低、流动性好、耐蚀性好等特点，主要成分(单位：wt％)Si4.5-5.2，Zn0.1-0.2，Ag0.8，Cu0.2-0.3，Al余量，熔化温度为560～600℃；
b)材料准备：基体金属选用3003防锈铝合金板材与波浪形带料；
c)材料清洗：将基体金属和钎料在60℃温度下用5％(质量分数)的氢氧化钠溶液浸泡1-2分钟除掉表面杂质和油污，再用大量水冲洗后干燥；
d)钎焊：钎焊在氮气保护的钎焊炉中进行，具体步骤依次为：
(1)将钎剂用分析纯的乙醇稀释成糊状；
(2)将钎剂刷涂于基体金属的待焊面上；
(3)将基体金属与钎料自下而上依次按照3003板材，4343铝硅钎料，3003波浪形带料，4343铝硅钎料，3003板材的顺序摆放，并用夹具夹紧；
(4)将氮气保护的钎焊炉温度预设至600℃，接通电源，开始升温；
(5)带炉温升到预定温度后，将装配好的工件放入炉子中，使工件均匀达到炉温后，保温15～20分钟；
(6)关闭电源，使工件在炉中冷却；
(7)取出工件；
e)焊后处理：用清水冲洗除去工件表面残留钎剂，再用10％硝酸溶液浸洗5-10分钟，取出工件烘干。
