Description

一种铁白铜厚壁管的氩弧焊焊接工艺
技术领域
本发明涉及一种氩弧焊焊接工艺，尤其是一种铁白铜厚壁管的氩弧焊焊接工艺。
背景技术
铁白铜以其良好的耐腐蚀性能和耐海水性能被广泛应用于船舶、钻井的海水系统和热交换系统，此时尤其以铁白铜管材及管路附件应用居多。然而传由于铁白铜强度低、热膨胀系数大、高温易氧化，故其焊接时易产生气泡和裂纹，尤以焊接接头处最易出现问题。
发明内容
本发明旨在解决上述问题，提供了一种铁白铜厚壁管的氩弧焊焊接工艺，其采用的技术方案如下：
一种铁白铜厚壁管的氩弧焊焊接工艺，其特征在于，其步骤依次为：
a) 材料准备：
（1）焊丝选用MONEL67焊丝；
（2）氩气纯度≥99.9999%
b) 加工破口：采用机械加工的方式，坡口型式为V型；
c) 焊前清理：将焊丝、焊件、V型坡口及坡口两侧的油污、水分、氧化膜清理干净，保证焊接处表面光洁；
d) 焊接：采用单面焊接双面成形焊接工艺对焊接部位，即V型坡口处进行焊接；
e) 焊后处理：焊后对焊缝进行清理，检查焊缝是否均匀、致密，有无裂纹、气孔、夹杂、未焊透、未熔合等缺陷，若有超标缺陷应去除缺陷后再进行补焊。
本发明具有如下优点：它具有工艺简单，容易掌握，焊接烧损少、成本低，焊接接头处焊缝致密、牢固、强度高，是一种品质优良的铁白铜厚壁管的氩弧焊焊接工艺。
附图说明
本发明的生产工艺流程图。
具体实施方式
下面结合附图和实例对本发明作进一步说明：
一种铁白铜厚壁管的氩弧焊焊接工艺，其特征在于，其步骤依次为：
a) 材料准备：
（1）焊丝选用MONEL67焊丝；
（2）氩气纯度≥99.9999%
b) 加工破口：采用机械加工的方式，坡口型式为V型；
c) 焊前清理：将焊丝、焊件、V型坡口及坡口两侧的油污、水分、氧化膜清理干净，保证焊接处表面光洁；
