重拾2006 深渊老宅 1102 字 2023-10-09

“那现在怎么办?”

周岩瞅了一眼已经断成两截的曲轴,无奈地翻了翻白眼:“还能怎么办,先放着呗!”

一旁的老娘,悄悄地凑到前面,朝满脸尴尬的周老爹冷哼了一声:“老周同志,咱们自己家的地,都还没耕呢!”

“儿子……”周正海试探性地问,“你有没有办法先糊弄一下,等春耕过去了,再换件?”

这个可以有!

断掉的地方打磨出坡口,用氩弧焊机焊接,完成之后,再做热处理就可以了。

“爸……”周岩看了看老头子,又看了看自家小叔,“你们先进屋吧,我打个电话……”

一个小时之后,青岩集团东阳分公司,给送过来几瓶氩气、一台氩弧焊机、一套热处理工具和焊丝等辅材。

周正海倒是见过修车的,可这么多稀奇古怪的工具还是第一次见,尤其是氩弧焊机。

“这些玩意儿,能行吗?”

“你就请好吧!”

周岩敢打包票,自然是有自信:在副本里,周岩曾经将很多工种刷到了八级,这其中,自然也包括焊接。

当然,焊接之前,需要将断口打磨出坡口,以便施焊。

在用掉了家里十几片合金打磨片,眼瞅着周老爹都要冒火了,终于将断口打磨成型。

接下来,就是焊接了。

先用点焊将断成两截的工件固定,接下来就是不停地堆焊了。

看着周岩不停的往焊口里堆焊丝,周老爹十分好奇,可又不好意思开口。

周岩花了两三个小时,终于在午饭之前,将断成两截的曲轴给焊接完成。

午饭时间到了,只是,看了找半天热闹的老娘似乎是忘了准备午饭了。

“自己动手,丰衣足食!”

话一出口,周岩的后脑勺上就挨了老娘一巴掌:“老娘又没缺你吃喝!”

有客人在,虽然有点晚了,可老娘还是“远程”指挥着周岩,做了六菜一汤。午饭的时候,借着酒劲儿,周老爹终于问了一个在心里憋了两个多小时的问题:“儿子,氩弧焊到底是怎么回事儿?”

“这个……”周岩面露难色,电焊倒还好解释,可涉及到惰性气体,初中跳了两级没学过化学的老爹,就有点麻爪了。

“那个……”周岩见老头子面色不善,只得硬着头皮解释道,“电焊的原理您老应该知道吧,跟节能灯差不多,瞬间高压产生的电弧击穿空气,融化金属……”

“普通的焊条,外面有药皮,能够保护焊丝不被空气氧化,”周岩小心翼翼盯着自家老爹,“氩弧焊的原理差不多,只不过药皮换成了氩气。”

“至于氩气这种气体,你可以理解为跟谁都玩不熟的二百五……”

午饭之后,还有合金钢的热处理。

合金钢的晶格密度要比普通的钢材大很多,而焊接完成之后,焊口出的合金钢,因为冷却,会产生应力。如果不降应力释放,曲轴的下场还会一样……

而热处理的工艺,相对比较简单:利用电热丝将工件加热到一定温度,然后施加保温,使应力缓慢释放。

周岩让人准备的热处理仪器,自动化程度比较高,布置好加热器、保温棉和温度传感器之后,直接在机器里设定加热温度和保温时间久可以了。
