Thaum vuamtitanium siab hlab ntsha, vim tias cov roj argon nqa los ntawm lub vuam nozzle tsuas yog tuaj yeem tiv thaiv lub vuam pas dej ua ke, thaum cov khoom siv vuam thiab nws cov cua sov cuam tshuam tsis muaj kev tiv thaiv roj, uas yog ib feem ntawm cov hlau tseem nyob ntawm qhov kub thiab txias. Thaum cov hlau titanium siab tshaj 400 degree, nws pib nqus oxygen thiab thaum nws siab tshaj 600 degree, nws pib nqus nitrogen. Nrog rau qhov nce ntawm oxidation degree, cov xim ntawm cov weld yuav hloov, thiab nws cov khoom siv kuj yuav deteriorate maj mam. Yog hais tias lub vuam yog nyiaj dawb, nws qhia tias tsis muaj oxidation, golden daj qhia me ntsis oxidation, xiav qhia me ntsis oxidation loj, thiab grey qhia oxidation loj.

Kev tshuaj xyuas xim yuav tsum tau ua nyob rau saum npoo ntawm tag nrho cov welds thiab tshav kub-tshem tawm tsam: thaum lub npoo yog nyiaj dawb thiab daj daj, nws tsis tuaj yeem kho; Xiav welded pob qij txha tuaj yeem siv rau qhov tsis tseem ceeb tom qab kev tshem tawm xiav; Welded pob qij txha ntawm lwm cov xim yuav tsum tau kho, thiab kev saib xyuas yuav tsum tau them rau lub sijhawm kho. Yog li ntawd,titanium siab hlab ntshayuav tsum tau them sai sai rau lub zog linear nyob rau hauv cov txheej txheem vuam, tswj lub vuam ceev thiab nruj me ntsis raws li cov txheej txheem vuam specification.
Raws li tus qauv tsim, qhov chaw vuam thiab qhov kub thiab txias yuav tsum yog 100 feem pua tshuaj xyuas nrog 10x magnifying iav tsis muaj undercut. 100 feem pua kev kuaj hluav taws xob tsis muaj kev puas tsuaj yog xav tau rau chav kawm A thiab B welds, thiab qib II yog tsim nyog. Nyob rau hauv cov ntaub ntawv ntawm over standard defects, lub defects yuav tsum tau muab tshem tawm ua ntej kho welding, thiab rov kuaj nrog rays kom txog rau thaum lawv tsim nyog. Qhov saum npoo ntawm tag nrho cov welds (lub taub qab sib koom ua ke thiab fillet sib koom ua ke) yuav tsum raug kuaj xyuas ua ntej thiab tom qab kuaj hydrostatic. Yog tias pom muaj qhov tsis txaus ntseeg, nws tuaj yeem polished. Yog tias tsim nyog, nws yuav tsum tau kho thiab rov kuaj dua los ntawm txoj kev nkag mus kom txog thaum nws tsim nyog. Cov kev ntsuas uas tsis yog kev puas tsuaj ntawmtitanium siab hlab ntsharau welds yog ho ntau dua li tus qauv tsim, uas yuav tsum tau them sai sai rau hauv cov txheej txheem tsim khoom.
