Lub hauv paus ntsiab lus ntawm S275JR kuj welded yeeb nkab vuam:

Tom qab cov workpieces tau ua ke, lub siab yog siv los ntawm electrode, thiab cov workpieces yog rhuab los ntawm cov hluav taws xob tiv thaiv los ntawm qhov tam sim no ntws los ntawm qhov chaw vuam, kom qhov vuam qhov mus txog lub zos melting los yog high-temperature yas xeev, thiab kev sib txuas yog ua tiav los ntawm kev sib xyaw ua ke ntawm cov cua sov thiab lub zog mechanical.

Lub hauv paus ntawm kev ua haujlwm vuam yog los ntawm Joule cov nyhuv tshav kub, uas feem ntau muaj peb yam tseem ceeb: tam sim no, lub sijhawm, thiab tsis kam. Ntawm lawv, tam sim no thiab lub sijhawm yog txiav txim siab los ntawm cov khoom siv vuam sab nraud; tsis kam yog muab faib ua lub cev tsis kam ntawm cov khoom siv vuam thiab kev sib cuag ntawm qhov chaw sib cuag. Lub cev tsis kam ntawm cov khoom yog txiav txim siab los ntawm cov khoom nws tus kheej, thiab kev tiv thaiv kev sib cuag nyob ntawm lub xeev ntawm cov khoom, electrode siab, cov khoom siv electrode, thiab lwm yam.

S275JR welded yeeb nkab vuam zoo soj ntsuam:

Ob txoj hauv kev yog kev sim tsis muaj kev puas tsuaj lossis kev sim ua kom puas tsuaj;
Kev kuaj tsis muaj kev puas tsuaj feem ntau yog xaiv kev kuaj ultrasonic (siv ultrasound kom tau txais cov duab ob sab ntawm lub vuam sib txuas yog qhov kev sim tsis muaj kev puas tsuaj thiab ua tau zoo) lossis kev kuaj X-ray (siv hluav taws xob nkag mus rau cov ntaub ntawv lossis cov khoom kuaj xyuas lawv sab hauv. tsis xws luag lossis txheeb xyuas lawv cov qauv siv lead ua raws li cov yam ntxwv ntawm kev sib txawv);
Kev ntsuam xyuas kev puas tsuaj feem ntau yog xaiv qhov ntsuas tensile lossis kev tshuaj xyuas metallographic. Kev ntsuas lub zog tensile tuaj yeem siv los kuaj xyuas cov khoom sib txuas lub zog. Metallographic tsom xam feem ntau yog siv los txheeb xyuas qhov sib txawv ntawm qhov sib txawv ntawm qhov vuam, lossis los xyuas seb puas muaj qhov tsis xws luag xws li qhov pores thiab tawg ntawm qhov chaw weld. Hauv kev tsim khoom, vuam zoo feem ntau lees paub los ntawm cov tsos, xws li xyuas seb puas muaj cov kab nrib pleb sab nraud ntawm cov qauv tom qab vuam, seb puas muaj oxidation discoloration loj, thiab seb puas muaj vuam spatter.
