Lub zog ntawm flux core hlau
Tam sim no peb to taub dab tsi flux core hlau yog, cia peb saib ze dua ntawm nws lub zog thiab kav ntev. Feem ntau, flux core hlau yog paub txog nws lub zog zoo heev thiab kev ua haujlwm vuam.
Ib qho ntawm cov tseem ceeb uas ua rau nws lub zog yog nws cov flux filling. Cov khoom siv flux ua raws li tus neeg sawv cev tiv thaiv, tiv thaiv kev tsim cov vuam tsis zoo thiab txhim kho qhov zoo ntawm vuam. Tsis tas li ntawd, cov flux tseem tuaj yeem pab tshem tawm cov impurities uas twb muaj lawm hauv cov hlau, uas ua rau muaj zog dua thiab huv dua.
Lwm qhov tseem ceeb uas ua rau lub zog ntawm flux core hlau yog nws cov muaj pes tsawg leeg. Flux core hlau feem ntau yog tsim los ntawm kev sib xyaw ntawm cov ntaub ntawv, suav nrog hlau, chromium, thiab npib tsib xee. Cov ntaub ntawv no muab lub zog zoo thiab ua haujlwm ntev, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov haujlwm vuam hnyav.
Zuag qhia tag nrho, flux core hlau yog qhov zoo siab rau nws lub zog thiab kev ua haujlwm vuam, ua rau nws yog qhov kev xaiv txhim khu kev qha rau cov kws tshaj lij vuam thiab cov neeg nyiam ua haujlwm zoo ib yam.
Hom flux core hlau
Muaj ntau ntau hom flux core xaim muaj nyob rau hauv kev ua lag luam niaj hnub no, txhua tus muaj nws tus kheej cov khoom tshwj xeeb thiab lub zog. Cia peb saib ntau hom flux core hlau thiab lawv piv li cas.
1. Self-shielded flux core hlau
Self-shielded flux core wire yog ib hom hlau uas tau tsim tshwj xeeb rau cov haujlwm vuam sab nraum zoov. Nws tsis tas yuav tsum muaj cov roj tiv thaiv cais tawm, vim cov khoom siv flux muaj peev xwm tiv thaiv cov vuam los ntawm cov kab mob thiab impurities.
Ib qho ntawm qhov zoo ntawm tus kheej-shielded flux core xaim yog tias nws tuaj yeem siv tau rau hauv cov huab cua, qhov twg cov roj thaiv ib txwm tuaj yeem tawg. Txawm li cas los xij, nws tsim cov pa luam yeeb thiab pa taws ntau heev, uas tuaj yeem ua rau muaj kev phom sij yog tias tsis siv qhov cua kom raug.
2. Gas-shielded flux core hlau
Gas-shielded flux core wire yog lwm qhov kev xaiv nrov, tshwj xeeb tshaj yog rau cov haujlwm vuam hauv tsev. Hom xov hlau no yuav tsum muaj cov roj tiv thaiv cais, uas feem ntau yog sib xyaw ntawm carbon dioxide thiab argon.
Gas-shielded flux core hlau ua rau cov pa taws tsawg dua thiab cov pa phem dua li cov hlau thaiv tus kheej, ua rau nws yog qhov kev xaiv zoo dua rau cov haujlwm vuam hauv tsev. Nws kuj tseem yuav tsim kom huv si thiab meej dua welds, ua rau nws yog ib qho kev xaiv nrov rau cov kws welds.
3. Dual-shielded flux core hlau
Dual-shielded flux core wire yog hom tshiab ntawm cov xaim uas sib txuas cov txiaj ntsig ntawm ob qho tib si tiv thaiv tus kheej thiab roj-shielded hlau. Nws yog tsim los tsim kom huv si, meej weld thaum tseem muaj peev xwm tswj tau sab nraum zoov vuam tej yam kev mob.
Dual-shielded flux core xaim yuav tsum muaj cov roj tiv thaiv cais, tab sis nws kuj muaj txheej txheej ntawm cov khoom siv flux ua rau hauv cov hlau. Qhov no ua rau muaj kev huv huv thiab meej dua, thaum tseem muab cov txiaj ntsig ntawm kev tiv thaiv tus kheej.
Zuag qhia tag nrho, txhua hom flux core hlau muaj nws cov txiaj ntsig tshwj xeeb thiab qhov tsis zoo. Nws yog ib qho tseem ceeb uas yuav tau xaiv txoj cai ntawm cov hlau rau koj qhov project vuam tshwj xeeb los xyuas kom meej qhov zoo tshaj plaws.
Xaus
Nyob rau hauv xaus, flux tub ntxhais hlau yog ib tug muaj zog thiab ruaj welding hlau uas paub txog nws zoo heev vuam kev kawm. Nws qhov tshwj xeeb muaj pes tsawg leeg, ua ke nrog nws cov khoom siv hauv flux, ua rau nws yog qhov kev xaiv nrov rau cov kws tshaj lij vuam thiab cov neeg nyiam nyiam sib xws.
Muaj ntau ntau hom flux core xaim muaj, txhua tus muaj nws tus kheej cov khoom tshwj xeeb thiab lub zog. Txawm hais tias koj xav tau cov hlau thaiv tus kheej rau kev sib txuas sab nraum zoov lossis cov hlau thaiv roj rau sab hauv tsev, muaj cov xaim hluav taws xob uas tsim nyog rau koj cov kev xav tau tshwj xeeb.
Zuag qhia tag nrho, yog tias koj tab tom nrhiav kom muaj zog thiab txhim khu kev qha vuam hlau rau koj qhov project tom ntej, flux core hlau yog qhov tsim nyog xav txog. Nws lub zog thiab kev ua haujlwm vuam ua rau nws muaj kev ntseeg siab rau cov neeg siv khoom thoob ntiaj teb.
