Kev taw qhia luv luv
Cam khwb cia hlau yog hlau-carbon alloy uas muaj ntau tshaj 2% carbon. Tam sim no, ntau tshaj 10 hom cam khwb cia hlau welding rods tuaj yeem muab rau hauv Suav teb, uas tuaj yeem xaiv raws li cov khoom siv hlau sib txawv, kev ua haujlwm sib txawv thiab qhov tseem ceeb ntawm vuam kho qhov chaw.
Cam khwb cia hlau yog cov khoom siv tsis zoo weldability vim nws cov ntsiab lus carbon siab, cov qauv tsis sib xws, thiab tsis tshua muaj plasticity. Nyob rau hauv cov txheej txheem vuam, nws yog ib qho yooj yim los tsim qhov tsis xws luag xws li lub qhov ncauj dawb, tawg thiab pores. Yog li ntawd, cam khwb cia hlau weld kho muaj ntau dua yuav tsum tau nyob rau hauv kev txawj ntse ntawm lub welder. Kev kho cam khwb cia hlau vuam tuaj yeem muab faib ua ob hom: preheating thiab txias vuam.
Tswv yim
Txhawm rau kom ntseeg tau tias cov nyhuv vuam, cov kev ntsuas hauv qab no tau pom zoo rau kev siv cov cam khwb cia hlau vuam thiab vuam:
1. Ua ntej tshem tawm cov av, xuab zeb, dej, xeb thiab lwm yam kab mob los ntawm cov khoom siv welded, thiab siv cov kev ntsuas xws li hom tsis xws luag, qhov qhib qhov zawj, qhov tawg ntawm lub qhov thiab cov duab ntawm lub pas dej molten.
2. Rau qhov preheated weldment, ua ntej preheat lub weldment mus txog 500 ~ 600 degree, xaiv qhov tsim nyog tam sim no, thiab txuas ntxiv weld, kom lub preheating kub yog ib txwm khaws cia thaum lub sij hawm vuam txheej txheem, thiab cov asbestos hmoov yog them los ntawm liab kub. xeev tom qab vuam. Los yog lwm cov ntaub ntawv rwb thaiv tsev, kom ua tiav qhov txias txias, yog qhov tsim nyog rau graphite nag lossis daus.
3. Rau cov khoom ua haujlwm txias-welded, txhawm rau kom tsis txhob muaj ntau dhau ntawm lub hauv paus hlau thiab txo cov txheej dawb-lub qhov ncauj, nyob rau hauv vuam, sim siv me me tam sim no, luv luv arc, nqaim hlaws, thiab hlaws luv (qhov ntev ntawm txhua hlaws feem ntau tsis tshaj). 50mm) thiab tom qab welding, rauj lub vuam los so kom txhob tawg. Thaum qhov kub poob qis dua 60 degree, txuas nws dua.
4. Ua tib zoo sau lub qhov arc thaum kaw lub arc kom tsis txhob tawg ntawm lub qhov arc.
