ThaumVuam cov kav dej me me-, Saib xyuas yuav tsum tau them tu slag, pas nrig thauj cov txheej txheem, kev hloov pauv ntawm cov pas dej molten thiab kev tshuaj ntsuam cov kev xav tau. Kev tu cov nplais yog kom tsis txhob muaj cov impurities los ntawm kev sib xyaw hauv thiab faus cov khoom plig zais; Tus pas nrig thauj cov qauv yuav tsum xyuam xim rau preheating, Qws xaiv thiab vuam txoj kev; Qhov kawg tshuaj xyuas yuav tsum xyuas kom meej tias kev xav tau weld ua tau raws cov kev xav tau. Tsuas yog los ntawm kev ua tej yam no zoo tuaj yeem ua tau zoo ntawm cov kav dej loj me.
1. Ntxuav Slag:Ua ntej vuam, ua tib zoo ntxuav lub saws ncig weld kom paub meej tias qhov kev nyiam huv thiab tiv thaiv kev cuam tshuam los ntawm kev sib xyaw hauv thiab burying zais cov phom sij.
2. QER thauj cov qauv:Ua ntej tawm tsam lub arc hauv kev siv overhead vuam txoj hauj lwm, thiab siv arc ntev ntev kom preheat rhead vuam txoj hauj lwm. Thaum lub sij hawm preheating preheating, txij li lub fluidity ntawm molten dropet yuav tsum tau muab pov tseg, thiab tom qab ntawd ib qho chaw kub thiab txias, thiab tom qab ntawd ib qho chaw kub thiab txias, thiab thaum xub thawj thiab thib ob thiab kab rov tav serrated bar kuj tseem siv tau). Thaum lub sijhawm cov txheej txheem no, lub arc luv yuav tsum tau tswj hwm rau kev siv vuam, thiab viav vias sib tw kom tsis txhob ua raws li qhov tsis zoo xws li undercut yam.
3. Molten pas dej hloov pauv:Nws yog ib qho tseem ceeb kom nco ntsoov tias thaum lub sijhawm vuam, koj yuav tsum ua tib zoo saib xyuas cov pa ntawm Molten thiab kom zoo ib yam nkaus, zoo nkauj heev, ci thiab meej.
4. Tshawb xyuas qhov zoo:Tsom mus rau kev kuaj xyuas seb tus weld tau tsim zoo thiab seb qhov siab ntau zuj zuj. Tus Weld zoo yuav tsum xyuas kom meej tias cov khoom nto muaj kev hloov pauv me me thiab tsis muaj qhov cuam tshuam.
