Lub vuam thiab kho txoj kev ntawm excavator thoob lub cev thiab thoob cov hniav yog raws li nram no:
Cov khoom siv thoob thiab nws cov weldability
1. Ntxuav qhov chaw vuam ua ntej vuam
Nws yog tshem tawm cov qub tawg vuam nqaij, nrog rau theem grinder sib tsoo los yog kev siv cov pa roj carbon arc cua dav hlau, tab sis lub dav hlau yuav tsum tau polished huv si hlau oxide.
2. Cov cua sov ua ntej yuav tsum tau ua ua ntej vuam
Yog tias ua tau, preheat qhov vuam txoj hauj lwm rau 100 degrees.Tom qab ntawd siv lub vuam pas nrig nrog ib txoj kab uas hla ntawm 3.2J507 rau vuam, thiab nres tom qab lub sij hawm luv luv ntawm vuam.Siv rauj los tsoo lub vuam thiab ntug ntawm qhov vuam.Tom qab lub vuam tiav lawm, siv rauj los tawm tsam kom txog thaum lub vuam yog qhov pib txias.Lub hom phiaj yog tso tawm qhov kev ntxhov siab, txij li kev kho cua sov tom qab vuam tsis tuaj yeem ua tau.
3. Cov khoom siv vuam tsim nyog yuav tsum tau xaiv rau vuam
Electrode hom yog ib qho tseem ceeb.Yog tias koj xav nkag siab txog yam khoom siv uas koj yuav tsum tau ua qee qhov kev ntsuam xyuas hlau ua npuas ncauj, ib qho kev sim tawm, thiab tom qab ntawd raws li kev faib tawm ntawm electrode ntawm kab.
4. Lub thoob lub cev thiab thoob cov hniav vuam ntawm excavator yuav tsum tau welded tag nrho
Thaum welding yuav tsum xyuas kom meej lub weld nkag mus, yog hais tias lub weld txoj hauj lwm sib txawv yuav loj nyob rau hauv lub nraub qaum phaj.
