Kev cai hlau vuam qhov chaw
Hlau vuamyog kev tsim kho (fabrication vuam) los yog sculptural txheej txheem ntawm kev koom tes hlau. Thaum lub sij hawm welding txheej txheem, cov khoom ua hauj lwm thiab cov solder yaj los yog tsis yaj los ua ib qho khoom siv ncaj qha koom.metalweldingpkos duab. Thaum lub sij hawm tus txheej txheem no, lub siab yog feem ntau yuav tsum tau mus koom lub weldment. Muaj ntau tshaj 40 txoj kev vuam hlau, uas feem ntau muab faib ua peb pawg: fusion vuam, siab vuam thiab brazing:
Fusion welding yog ib txoj hauv kev uas cov khoom sib txuas ua haujlwm tau rhuab mus rau lub xeev molten thaum lub sij hawm vuam txheej txheem thiab vuam ua tiav yam tsis muaj siab.
Kev kub siab vuam yog ua kom ob daim ntawv ua haujlwm paub txog kev sib koom ua ke hauv lub xeev ruaj khov, tseem hu ua solid-state welding.
Brazing yog siv cov khoom siv hlau nrog qhov qis melting point tshaj qhov chaw ua haujlwm raws li cov khoom siv solder, ua kom sov cov khoom ua haujlwm thiab cov khoom siv rau qhov kub siab tshaj qhov melting point ntawm lub solder thiab qis dua qhov melting point ntawm lub workpiece, siv. kua nplaum kom ntub cov khoom ua haujlwm, sau qhov sib txawv ntawm qhov sib txawv thiab ua tiav Inter-diffusion ntawm atoms, kom paub txog txoj kev vuam.
