Na'urar gwajin taurin Vickers na Shandong Shancai/Laizhou Laihua Kayan Gwaji na iya yin gwajin taurin akan sassan walda ko wuraren walda.
Dangane da ƙimar taurin da aka auna, ana iya tantance ingancin walda da canje-canjen ƙarfe. Misali, tsayin daka na iya kasancewa saboda shigar da zafi da yawa yayin walda, yayin da ƙarancin taurin zai iya nuna rashin isasshen walda ko matsalolin ingancin kayan.
Tsarin ma'aunin Vickers da aka saita zai gudanar da cikakken shirin gwaji na atomatik da nunawa da rikodin sakamakon daidai.
Don sakamakon gwajin aunawa, za a iya samar da rahoton hoto mai dacewa ta atomatik.
Yana da mahimmanci a lura cewa lokacin zabar yankin wakilci na;walda a matsayin wurin gwaji, tabbatar da cewa wannan yanki ba shi da pores, fasa ko wasu lahani waɗanda zasu iya shafar sakamakon gwajin.
