Monolithic Vuam Joint

Hlau lug yog siv nyob rau hauv tag nrho cov lag luam, tab sis, hmoov tsis, tsis yog txhua yam khoom muaj peev xwm raug muab pov rau hauv ib qhov cub los yog nyob rau hauv daim ntawv no. Ib feem npaj txhij ua ke tsis yog ib qho yooj yim kom tuaj koom nrog rivets los yog carving. Nws yog rau cov rooj plaub no uas yuav tsum tau vuam siv (lossis vuam sib txuas) - txoj kev txhim kho cov khoom siv hlau, uas yog raws li kev sib txuas hauv nruab nrab. Cov ntawv qhia thiab ntau hom kev vuam yog cov ntau heev, tab sis cov ntsiab lus tseem ceeb yog peb leeg, uas tau muab cais ua nyias pawg. Qhov no yog ib txoj hauv kev kho tshuab, thermal thiab complex - thermomechanical. Mechanical welding yog txawv los ntawm kev txuas ntawm qhov chaw nyob rau hauv siab los yog tawg, ultrasound, kev sib txhuam. Thermal vuam yog ib txoj kev ntshav, fais fab, laser, hluav taws xob nqaj hlau thiab cov zoo li.

Cov yam ntxwv ntawm tus ntiv tes thiab thermal vuam

Yuav luag txhua hom thermal welding muaj kev siv cov xov tooj cua tshwj xeeb. Hauv cov hlua caj dab, cov hlua hlau welding muaj nyob rau hauv electrode, nyob rau lwm qhov txhua tus neeg hlau yog tam sim no ua ib qho chaw cais noj rau qhov chaw welding. Nws muaj peev xwm sib txawv ntawm lub cev thiab cov khoom - txhua weld hlau xav tau nws tus kheej hlau nrog tshwj xeeb cov yam ntxwv uas ua tau raws li cov cai ntawm cov pob qij txhaws.

Kev kho lossis kho kom zoo dua tshiab ntawm lub sijhawm ua haujlwm yuav raug coj los ntawm ib txoj kev ntawm kev sib txuas lus - los ntawm kev thov kom poob los yog nias ntawm ib txheej hlau tshiab. Feem ntau yog tib yam hlau siv rau qhov sib txoos, tab sis tus mob no tsis tsim nyog. Qee zaum, yuav kom txhim kho cov khoom siv dag zog thiab kev ua haujlwm rau vuam, lwm tus hlau nrog sib txawv tshuaj muaj pes tsawg leeg. Piv txwv, nyob hauv ib lub thoob rau cov khawb av, cov hniav yog ua los ntawm ib lub zog muaj zog nrog cov pa roj carbon ntsiab lus.

Welding kev twb kev txuas: kos cov hlua hlau

Npav ua rau nws yooj yim los mus txiav txim yog dab tsi zoo ntawm hlau yuav tsum tau siv no rau ib qho hom vuam ua hauj lwm. Tus thawj tug lej qhia lub cheeb thiab cov tsab ntawv cim cov cim zoo ntawm cov hlau (hlau caij). Cov ntawv "Sv" txhais tias "welding wire", thiab cov duab tom qab lawv sawv cev cov pa feem qis ntawm 0.01 feem pua. Cov ntawv tom qab xam yog qhov feem pua ntawm cov khoom sib thooj ntawm cov hlau. Alloying ntsiab yog qhia: A - nitrogen, B - Nb, V - W, T - Manganese, D - Tooj K - cobalt, M - molybdenum, H - npib tsib xee, phosphorus n- C - Si, T - titanium, F - Vanadium, X - chromium, U - txhuas. Ces muaj ib daim duab rau feem pua ntawm cov khoom no hauv cov xaim. Txawm li cas los xij, thaum qhov feem pua tsawg dua ib qho, ces muab tsis tau. Piv txwv li, lub xov hlau welding yog 08g2s, qhov twg cov ntsiab lus carbon yog 0.08%, yuav luag 2% ntawm manganese thiab tsawg tshaj li 1% ntawm silicon.
