Cov txheej txheem welded yeeb nkab ntau lawm, cuam tshuam rau qhov zoo ntawm cov khoom muaj ntau tshaj ib cov yeeb nkab, cov ntaub ntawv tseem ceeb, vuam tshuab thiab yob suav uas yog pib kho.

Qhov tseem ceeb los saib cov geometric qhov ntev. Sawb geometry cuam tshuam rau qhov zoo ntawm cov hlau sawb dav thaum tsawg dua qhov tso cai sib txawv, lub extrusion siab welded steel yeeb nkab yog txo, ua rau cov yeeb nkab vuam vuam tsis muaj zog, tawg los yog qhib raj. Thaum qhov dav ntawm lub sawb ntau dua qhov kev ua siab ntev, lub zog nias yog nce thaum lub welded steel yeeb nkab, steel yeeb nkab welds tshwm beak, lap welding thiab lwm yam vuam tsis xws luag los yog burrs. Yog li ntawd, qhov sib txawv ntawm qhov dav ntawm lub sawb, tsis tsuas yog cuam tshuam qhov tseeb ntawm sab nraud ntawm cov yeeb nkab steel, tab sis kuj cuam tshuam rau qhov zoo ntawm cov yeeb nkab steel.
Qhov yuav tsum tau muaj rau tib seem thickness sib txawv tsis tshaj qhov predetermined tus nqi ntawm cov yeeb nkab steel, uas yuav tsum tau ib tug high degree ntawm uniformity ntawm phab ntsa thickness ntawm steel yeeb nkab, fluctuations nyob rau hauv lub thickness ntawm lub sawb, tib lub ntim yuav raug xa mus rau phab ntsa. thickness ntawm kev tso cai tus nqi ntawm tiav steel strip thickness sib txawv tshaj qhov sib txawv yog li ntawd ib tug loj tus naj npawb ntawm steel thickness tshaj qhov tso cai sib txawv thiab raug txim mus pov tseg. Kev hloov pauv hauv lub thickness ntawm cov tiav steel thickness tsuas yog cuam tshuam qhov raug. Lub caij no, txij li cov sawb thickness sib txawv, cov yeeb nkab steel thaum lub sij hawm vuam, extrusion siab thiab vuam kub instability, ua rau tsis ruaj tsis khov weld zoo steel vuam.

Tsis tas li ntawd, txij li cov khoom siv hauv steel sandwich muaj qhov tsis xws luag, impurities, xws li trachoma, yog qhov tseem ceeb cuam tshuam rau cov hlau zoo. Yog li ntawd, ua ntej steel welding, mus xyuas txhua yob strip nto zoo thiab geometry ntawm lub sawb zoo tsis ua raws li cov qauv, tsis ntau lawm, thiaj li yuav zam tsis tas yuav poob.
