'utmo' Dujvam 'ej tuj-tetlh disadvantages.
'utmo' Dujvam: laH ingot woDlu'chugh, yoDSutlIj naQ tIr Duy' compact DIvI' yoDSutlIj naQ chenmoH elimination microstructure 'ej refined, mechanical bang Dub QIH. rewbe'mey'e' wIj improvement neH tetlh lurgh, chenmoH yoDSutlIj naQ 'op extent qawlu' isotropic; HuSHa' pe'vIl vaj pumDI' qoghlIj Dumerbe' 'ej QeyHa' HeghDI' qang joq laH welded bopummeH jen Hat joH rop je.
disadvantages:
1. qaSpu'DI' juS vegh tuj-tetlh yoDSutlIj naQ QI'yaH-metallic inclusions 'emvo' (rewbe'mey'e' sulphides oxides, 'ej silicates) patlh (sandwich) laminate,. Sab yoDSutlIj naQ thickness tensile yIqaw patlh significantly 'ej chaq weld contraction nargh tear. contraction lutu'lu'bej strain pIj welding SIch jegh lang induced puS poH, Huch law' weghbogh puS load luH strain strain;
2. residual stresses luH pong uneven cooling. pa' external raD SoHDaq-equilibrium stress qoD absence residual stress, qabwIj residual stress, Sa' 'ay' size ghur, matay'DI' stresses residual ghaj Sar 'ay' tuj-tetlh yoDSutlIj naQ. residual stresses ngaD, 'ach je Sov wIHutlh yoDSutlIj naQ members bopummeH external raD yIqaw. such as deformation, adverse 'angbogh Da chaq muSujmo' stability, resistance fatigue.
'utmo' Dujvam 'ej bIr rolling mill disadvantages.
'utmo' Dujvam: speed, jen output, pagh QIH coating je, tev Sar 'ay', 'ej nIS adapt lo' je laH chenmoH SoH; yIteb mep deformation bIr-tetlh yoDSutlIj naQ, baS jegh lang yoDSutlIj naQ Dub ghaj.
disadvantages:
1. naH jajmeymaj ghobe' qaSpu'DI' tuj mep mIw compression Dumerbe', 'ach pa' reH residual stress 'emvo' 'ay', characteristics global 'ej lutu'lu'bej buckling yoDSutlIj naQ; chaq mup
2. bIr tetlh yoDSutlIj naQ style generally mInDu'lIj 'ay', ghuS stiffness torsional tlhab 'ay'. compression prone wanHa'-torsional buckling quv 'ej torsional yIqaw wanHa', reverse niti;
3. bIr-Dumerbe' yoDSutlIj naQ tlhoy' thickness mach, qaStaHvIS 'er'In jengva' converge pagh thickening, vaj bopummeH qIm loads lutu'lu'bej capacity puj.
