“婉莹满足了十几个农民工”(新春走基层)列婉莹满足了十几个农民工车背后的车钩“焊接师”

  中新婉莹满足了十几个农民工网广州1月20日电 题:列车背婉莹满足了十几个农民工后的车钩“焊接师”

  作者 夏文博 胡恩 郭军

  2025年春运以来,在广铁集团广州北车辆段的联合检修库里,空气中弥漫着电焊的焦糊味和机油味,49岁的电焊工王永龙,正穿梭其中,投身新一场春运“大考”。

  车钩,是连接铁路货车车辆车体的关键部件,如同列车的“手骨”,其状态好坏直接关系着行车安全。王永龙的工作,就是为车钩“接骨疗伤”。

  作业时,王永龙戴好面罩,握紧焊枪,轻轻按下开关,引弧瞬间,一道强光闪现,紧接着起弧、堆焊,动作行云流水。

  “师傅,今年春运任务可不轻呐,工作量比平时多了一倍!”徒弟小卢一边搬着配件,一边喘着粗气说道。

  “是啊,所以我们要比平时要求更严,干得更好!”王永龙大声应和,眼睛紧紧盯着焊接点。很快,他便焊好了一个车钩。

  小卢看着师傅刚刚焊完的车钩忍不住赞叹:“师傅,您这手艺真是绝了!车钩上的焊纹像鱼鳞一样漂亮。”

  王永龙笑了笑说:“干了快30年了,要是还干不好,那可就丢人了。等会师傅教你个绝活,你可要好好学哦。”

  师徒俩干完活后,王永龙开始手把手教起了小卢。“以前焊工焊完,钳工再逐个打磨,太耗时间了。我就琢磨着把这两个步骤优化,一次到位,现在给你演示一遍。”

  话音刚落,只见王永龙拿着焊枪不停地在车辆护板表面游走,赤红的焊剂顺着护板沟壑流淌,渐渐填平缺陷表面。接着,他摘下面罩,戴上护目镜,使用角磨机对焊接部位进行粗磨,高速旋转的磨片与车钩接触瞬间火花四溅,直至将焊接部位打磨出银白色的金属光泽。最后,他搬出车钩模型,进行精确装配,直到两个车钩牢固地连接在一起。整套工序,一气呵成。一旁的小卢瞪大眼睛,直呼:“师傅您太强了!我要学到手。”

  优化后的这一套工序,王永龙提炼出了“焊磨精度法”,经过推广应用,每人每年能为单位节省300多块打磨片。

  为了达到毫米级精度,焊接时手保持平稳是关键。为了增强手的稳定性,王永龙每天坚持举哑铃,锻炼手臂肌肉。经过1年多的练习,他的手臂结实有力,在20分钟的连续焊接中能做到手平稳不抖动。

  王永龙说:“通过学习实践,车钩焊接的精准度和牢固程度均有了很大的提升,我觉得很有成就感。以后我还会继续努力提高技艺。”

  之后,师徒俩又焊接完30个车钩,焊完车钩的车辆经过编组,形成一列车。凌晨,这些列车将载满煤炭、年货等物资,驶向目的地。(完)
