Lub txiv ntseej weld yog ib lub txiv ntoo uas tsim rau vuam sab nraum lub txiv ntoo. Nws yog feem ntau ua los ntawm cov khoom siv weldable thiab yog tuab thiab haum rau kev vuam. Vuam yog sib npaug rau ob qho chaw sib cais raws li ib tug lej, thiab cov hlau yog melted ntawm qhov kub thiab sib xyaw. Thaum txias dua ua ke, cov hlau yuav muab ntxiv rau hauv nruab nrab, thiab sab hauv yog cov nyhuv ntawm qhov sib xyaw ua kom muaj zog, thiab lub zog yog feem ntau tshaj qhov muaj zog ntawm leej niam. Lub vuam tsis ntawm qhov kev sim nyob ntawm lub voos fusion loj, kho cov vuam tsis raws li fusion loj me, kom txog thaum tshem tawm tsis xws luag. Ntawm chav kawm, qhov zoo ntawm cov vuam yog txuas nrog kev kho mob ua ntej, kev ntxuav, roj, thiab lwm yam.
Weld txiv ntoo
Thaum lub sij hawm welding, lub workpiece thiab lub lauj kaub yaj rau ib qho chaw molten, thiab lub pas dej ua kom zoo zoo thiab tom qab tsim cov kev sib txuas ntawm cov ntaub ntawv. Hauv txoj haujlwm no, feem ntau nws tsim nyog yuav tau thov kev pabcuam. Muaj ntau qhov chaw vuam vias, xws li cov nplaim taws roj carbon monoxide, cov hlua khi, las, electronical beams, txhuam, thiab ultrasonics. Txog rau thaum xaus ntawm lub xyoo pua puv 19, txoj kev sib tshuam ntawm kev siv welding tsuas yog hlau forging uas tau siv los ntawm blacksmiths for centuries. Cov kev ua haujlwm uas nyuam qhuav siv tam sim no tau tshwm sim rau thaum xaus ntawm lub xyoo pua puv 19, thawj zaug nrog arc vuam thiab cov pa oxygen cov pa taws, thiab tom qab nrog lub ntsuas kev ua haujlwm. Nyob rau xyoo pua 20th, pib ntawm Thawj Ntu thiab Thoob Ntiaj Teb Tsov Rog, qhov kev xav tau rau kev pheej yig, kev sib txuas kev txhim khu kev sib txuas rau cov khoom siv tub rog loj heev, yog li txhawb kev tsim cov cuab yeej siv welding. Niaj hnub no, nrog rau kev siv dav hlau vuam robots hauv kev siv ntawv, cov neeg tshawb xyuas tseem tab tom kawm txog kev vuam vias thiab txuas ntxiv tsim cov kev siv welding tshiab kom ntxiv txhim kho qhov vuam zoo.
Kev tsim cov txheej txheem yog cov khoom ntawm cov khoom ua haujlwm tau siv (tib yam los yog txawv), rhaub los yog pressurized los yog ob leeg, thiab nrog los yog tsis muaj cov ntaub ntawv muab khoom siv, cov khoom ntawm cov khoom ua haujlwm tau ua nyob nruab nrab ntawm atoms tsim txoj kev txuas mus tas li, Welded nuts yog fasteners nrog internal threads uas siv nrog bolts. Muaj sab hauv thiab siv cov ntsia hlau sib kis mus rau qhov chaw ua haujlwm lossis qhov chaw ua haujlwm.

Kev zoo thiab qhov tsis zoo ntawm kev siv welding, lub zog yog tus loj, thiab kev siv ntau yam, nyias thiab tuab yuav ua tau, tab sis vim muaj qhov kub siab tuaj yeem ua kom deformation ntawm lub connector, thiab tsis tuaj yeem ua dejnum, thiab qee cov hlau nyob tsis tau yuav tau welded los ntawm txoj kev niaj hnub, xws li txhuas, magnesium, thiab lwm yam., xav tau kev tiv thaiv roj los yog argon arc vuam, yuav tsum ua cov cuab yeej siv thiab kev kho
