Dab tsi yog qhov forging theem ntawm nruab nrab zaus qhov chaw vuam tshuab?

Lub forging theem ntawm ib tug nruab nrab zausqhov chaw vuam tshuabhais txog cov txheej txheem uas cov electrode txuas ntxiv ua kom lub zog ntawm qhov vuam taw tes tom qab vuam tam sim no raug txiav tawm. Thaum lub sij hawm no, lub weld point yog compacted los xyuas kom meej nws solidity. Thaum lub hwj chim raug txiav tawm, cov tub ntxhais molten pib txias thiab crystallize nyob rau hauv lub plhaub hlau, tab sis nws yuav tsis ntsws dawb.

Tsis muaj qhov siab, qhov taw tes weld yog qhov ua rau qhov shrinkage thiab tawg, uas tuaj yeem cuam tshuam nws lub zog. Electrode siab yuav tsum tau tswj xyuas tom qab fais fab tuag kom txog rau thaum lub molten core hlau tag solidifies, thiab lub sij hawm ntawm forging nyob ntawm lub thickness ntawm lub workpiece.

Rau cov khoom ua haujlwm tuab nrog cov hlau nplaum tuab nyob ib ncig ntawm cov tub ntxhais molten, kev siv dag zog ntau ntxiv yuav tsim nyog, tab sis lub sij hawm thiab lub sij hawm ntawm kev nce siab yuav tsum tau ua tib zoo tswj. Kev thov ntxov dhau ntawm lub siab tuaj yeem ua rau cov hlau molten nyem tawm, thaum daim ntawv thov lig dhau lawm yuav ua rau cov hlau khov kho yam tsis muaj forging zoo. Feem ntau, nce forging siab yog siv li ntawm 0-0.2 vib nas this tom qab fais fab tuag.

Cov saum toj no piav qhia txog cov txheej txheem dav dav ntawm weld point tsim. Hauv kev tsim khoom tiag tiag, kev ntsuas cov txheej txheem tshwj xeeb feem ntau tau txais los ntawm cov khoom sib txawv, cov qauv, thiab cov kev xav tau ntawm vuam zoo.

Rau cov ntaub ntawv uas ua rau kub tawg, ntxiv qeeb txias mem tes vuam cov tswv yim yuav raug siv los txo cov solidification tus nqi ntawm cov molten core. Rau quenched thiab tempered cov ntaub ntawv, tom qab-weld kev kho cua sov ntawm ob lub electrodes yuav ua tau los txhim kho lub brittle quenching qauv tshwm sim los ntawm ceev cua sov thiab txias.

Nyob rau hauv cov nqe lus ntawm daim ntawv thov siab, lub eeb-puab, stepped, los yog ntau-kauj ruam electrode siab cycles tej zaum yuav raug siv los ua kom tau raws li qhov yuav tsum tau welding ntawm qhov chaw nrog cov qauv zoo sib txawv.
