【中国梦·大国工匠篇】国家级技能大师姜涛:干好一件事,就会有收获!

2017-06-16 08:13:25   国际在线

2015年9月,中国新型运载火箭“长征六号”成功发射,并创造“一箭20星”的亚洲纪录。姜涛带领团队承担“长征六号”火箭运输起竖系统和发射台项目中的翻转起竖机构焊接任务,力助“长征六号”成功发射。

在同事的眼中,姜涛用手中的焊枪把航天精神演绎得更加耀眼。

姜涛演示搅拌摩擦焊技术

在某型号产品焊接中,有一块10米长的大型结构件,用常规方法焊接,会造成大于0.1毫米的误差,不但延误交付进度,还浪费材料。考虑到结构件较大,焊接时易产生变形,姜涛根据生产实践,总结出一套合理的焊接顺序和工艺参数,提出了对称焊接后再用火焰矫正的方法,结构件一次交验合格率就由原来的60%提高到了95%。

在焊接某型号发射箱的任务中,由于发射箱口径只有200毫米,人钻不进去,但又要保证内部平滑,3米长的箱体,从一端到另一端误差不大于1毫米。铝合金材质极易变形,而且在颜色上不会变化,看不出是否变形,温度超过300度就很容易自己塌下来,很难控制。在这样严苛的要求下,姜涛通过自制内撑工装和抱箍工装,保证箱体内外部的变形量,同时在焊接时精准控制热输入,有效控制变形量,从而圆满地完成了生产任务。

一步一个脚印,一走就是30年,2013年,国家人力资源和社会保障部以焊工姜涛的名字命名,成立了“姜涛国家级技能大师工作室”。姜涛以自己扎实的工作作风、过硬的技术本领,影响带动着身边的每一位同志。30年兢兢业业,30年焊花灿烂,姜涛这一生,手执焊枪只做了一件事,但却做到极致。
