Kauv welded yeeb nkab units txheej txheem sawb hlau rau hauv kauv welded kav los ntawm kev sib koom ua haujlwm ntawm kev sib kis thiab kev tswj hluav taws xob. Ua ntej, lub uncoiler unwinds lub sawb hlau, thiab ib tug leveler tshem tawm kev ntxhov siab nyob rau hauv (leveling raug ± 0.5mm). Tom qab ntawd, lub tshuab tsim siv ntau cov txheej txheem ntawm cov chais kom coil cov sawb hlau rau hauv cov duab kauv (kauv lub kaum sab xis adjustable ntawm 30℃mus rau 85 degree), kom ntseeg tau cov ntug kev sib dhos. Cov txheej txheem vuam siv submerged arc vuam (tam sim no 400{13}}1200A, qhov hluav taws xob 28-40V), thiab qhov vuam ceev tau hloov kho raws sijhawm (0.5-3m / min) kom ntseeg tau tias vuam zoo (raws li API 5L cov qauv). Lub tshuab sizing calibrates txheej kab ntawm cov yeeb nkab (yuam kev ± 0.2%), thiab thaum kawg, nws yog txiav mus rau lub teeb ntev. Cov thev naus laus zis no tsim nyog rau kev tsim cov roj / roj pipeline, sib txuas ua haujlwm ua haujlwm siab (muaj peev xwm 20-50 tons / teev) nrog kev siv hluav taws xob tsawg.
