Kev tsim cov txheej txheem ntawm cov yeeb nkab welded feem ntau suav nrog ntau theem xws li kev npaj cov khoom siv raw, stamping, vuam, kev kho cua sov, kev kho deg, thiab kev tshuaj xyuas zoo. Thaum lub sij hawm splicing manufacturing, nruj yuav tsum tau muab tso rau ntawm weld kev taw qhia, cia tsuas radial thiab circumferential welds; qhov kev ncua deb yuav tsum siab tshaj peb npaug ntawm phab ntsa tuab thiab tsis pub tsawg tshaj 100 hli kom tsis txhob muaj cua sov- thaj tsam cuam tshuam. Tom qab splicing, weld seams ntawm tsim cov yeeb nkab caps yuav tsum tau siab tshaj - feem pua radiographic los yog ultrasonic kuaj, xws li 99.9% radiographic kuaj, nrog rau qib txais raws li qhov yuav tsum tau rau lub plhaub khoom.
Pulse-echo ultrasonic testing and radiographic testing is the application non-destructive test method. Pulse-echo ultrasonic kuaj yog tsim nyog rau kev kuaj xyuas qhov tsis xws luag xws li porosity, inclusions, thiab tawg hauv tuab- cov kav dej; Kev kuaj hluav taws xob tuaj yeem kuaj pom qhov tsis xws li porosity, slag inclusions, nkag mus tsis tiav, thiab tsis muaj fusion ntawm qhov kawg ntawm cov kav dej thiab hauv thaj chaw welded, tshwj xeeb tshaj yog qhov zoo thaum kuaj ultrasonic txwv.
