Txij li thaum xyoo 1930, nrog rau kev txhim kho sai ntawm cov khoom siv zoo tshaj plaws ntawm cov hlau txuas txuas txuas ntxiv thiab kev nce qib ntawm vuam thiab tshuaj xyuas tshuab, qhov zoo ntawm cov vuam seam yog txhim kho tas li, ntau yam specifications ntawm welded steel yeeb nkab yog nce, thiab ntau dua. thiab ntau qhov chaw los hloov cov seamless steel yeeb nkab. Welded steel yeeb nkab yog muab faib ua ncaj seam welded yeeb nkab thiab kauv welded yeeb nkab raws li daim ntawv ntawm weld seam. Kev faib tawm los ntawm cov txheej txheem ntau lawm: txheej txheem kev faib tawm - arc welded yeeb nkab, tsis kam welded yeeb nkab, (high-frequency, low-frequency) gas welded yeeb nkab, rauv welded yeeb nkab.
Me me txoj kab uas hla welded yeeb nkab siv ncaj seam vuam, txoj kab uas hla loj welded yeeb nkab yog ntau kauv vuam; Raws li cov duab ntawm qhov kawg ntawm cov yeeb nkab yog muab faib ua puag ncig welded yeeb nkab thiab zoo li tus (square, rectangular, thiab lwm yam) welded yeeb nkab; Raws li cov khoom siv thiab siv ntau hom welded steel yeeb nkab rau kev thauj cov dej hauv mines, galvanized welded steel yeeb nkab rau cov dej tsis tshua muaj siab, welded steel yeeb nkab rau txoj siv conveyor yob, thiab lwm yam. Raws li lub teb chaws tus qauv tam sim no nyob rau hauv cov lus qhia me me, raws li cov kab loj loj * phab ntsa thickness ntawm me me mus rau qhov loj.
