Kauv welded yeeb nkabntau lawm siv kub dov kauj.Cov ntsiab lus alloy ntawm cov kauj yog feem ntau qis dua cov qib zoo sib xws ntawm cov phaj steel, txhim kho qhov weldability ntawm kauv welded yeeb nkab.Vim lub dov kev taw qhia ntawm kauv welded yeeb nkab coil yog tsis perpendicular rau cov yeeb nkab axis kev taw qhia, lub tawg kuj ntawm cov kauv welded yeeb nkab cov ntaub ntawv.

Vim tias qhov kev ua tau zoo ntawm cov kav raj xaim, thaum cov welded welded yeeb nkab blasting tshwm sim, cov weld raug kev nyuaj siab thiab kev ntxhov siab me me, blasting lub qhov ncauj feem ntau tsis yog lub hauv paus ntawm cov kauv vuam, yog li kev ruaj ntseg dua.Kauv weld nyob ze ntawm qhov tsis xws luag nrog rau qhov sib npaug spiral weld quab yuam me me, yog li qhov kev pheej hmoo ntawm kev nthuav dav tsis yog.

Cov yeeb nkab steel raug rau sab hauv siab, feem ntau nyob rau hauv phab ntsa ntawm ob lub ntsiab ntawm kev siv quab yuam, radial stress δY thiab axial stress δX.Weld resultant stress δ = δY (l/4sin2α + cos2α) 1/2, uas, α yog lub kaum sab xis ntawm lub kauv vuam yeeb nkab.Lub kaum sab xis ntawm cov kauv vuam yeeb nkab feem ntau yog 50-75 degrees, yog li cov kauv weld loj tshwm sim los ntawm kev ntxhov siab.Nyob rau hauv tib txoj hauj lwm nyob rau hauv lub siab ntawm tib txoj kab uas hla kauv welded yeeb nkab phab ntsa thickness yuav txo tau ntau, kauv yeeb nkab cog yuav ua tau rau hauv ib tug me me caliber.
