第28章鱼鳞纹(1 / 2)

大国重坦 华东之雄 1068 字 2022-03-22

罗荣昌第一个扭回头来,揉着眼睛,还好,被闪了一下,没太大的事,秦振华倒是没说错,的确就是几下的事,嗯,现在就看看效果,究竟是烧了个大窟窿,还是一堆焊渣?

当带着这种想法望过去的时候,看清了秦振华的那条焊缝,顿时就愣住了。

刚刚焊接过的焊缝,带着金属特有的光泽,在阳光下,闪闪发光,焊缝虽然只有两厘米长,但是,清晰可见上面的焊点形成了一个个鱼鳞一般的细纹,这居然是焊工手艺里面的最高境界,鱼鳞纹!

最标准的焊缝,出来的就是这样的效果,就像是一片片的鱼鳞,均匀,紧密,想要达到这样的效果,至少要是三年的老师傅才行,除了焊接电流大小,还有焊枪与工件夹角角度、焊枪运条角度及宽度、焊接速度、工件厚度等等,多方面的因素有关,想要焊接成这样的完美效果,那可不容易!

老师傅们都得认认真真地对着焊,才能够焊出来,秦振华呢?这个学徒工,居然就做到这一点了?

“差点把我弄瞎,秦振华,谁和你一起干活儿,谁倒霉!”李长江嘟囔了两句,也凑过来了头,当看到那均匀的焊缝,那完美的鱼鳞的时候,李长江顿时就呆住了:“这是你焊接的?”

“是啊,李师傅,你看我这金刚钻,还可以吧?”秦振华说道。

刚刚还说人家没有金刚钻,就别揽瓷器活儿,结果,秦振华就露了一手,还好因为李长江和老秦的关系比较好,没有把话说的太绝,否则的话,就圆不回来了,就会像刘建志那么被打脸打的呱呱响。

“你是怎么做到的?”李长江问道,他没有理会秦振华刚刚问话,现在,他心中更多的是奇怪,秦振华,才进厂几天?焊把子还没拿过呢吧?怎么会突然露这么一手?

“很简单啊,首先看钢材的厚度,选择对应的电流,这种油箱,电流稍大就会烧穿,所以,我只把电流调节到了六十而已。主要还是手上的功夫,想要焊接出鱼尾纹,手要抖着前进,向前延伸十五度左右,这样,融化出来的焊药和焊丝,正好可以溜着过去,手在抖的时候,同时推着这股热流,以大概每秒钟一厘米的速度前进,前面有一个小小的弧度,这里是符合三角函数运算的…”

谁见过这么焊接的?说起焊接来,居然举出来了这么多的实际数字来?老师傅带徒弟,靠的都是经验,手上的经验,这就好像学外语一样,不要说出一二三来,只要靠语感,就该知道选择哪个单词了。

但是,秦振华就硬是给总结出来了!

“我说的不是这个,我是说,你怎么会焊接?你练过多久了?”

秦振华皱起来了眉头,似乎是在回忆,然后,还用手指头数了一下:“大概,三个月吧!”

三个月,到这个水平,那也绝对是不容易的了,不过,你入厂不是才几天吗?

上哪里焊接三个月去?

“哦,我在生产队的时候,焊好了油箱,就被他们叫到县城里面去了,他们县城有个修理厂,在那里,我帮了一段时间工。”

原来是这样!也就是说,秦振华绝对不是什么都不会,他也是有底子的啊,要是在那里帮过忙,练习过,有这手头的功夫,也算是不错的了。
