Izinto ezilungileyo ze Ndabona umbhobho wentsimbi
Iyakwazi ukutshabalalisa i-ingot casting structure, ihlambulule ingqolowa yentsimbi, kwaye isuse iziphene ze-microstructure, ukwenzela ukuba isakhiwo sensimbi sinobunzima kwaye iimpawu zomatshini ziphuculwe. Olu phuculo lubonakaliswa ikakhulu kwicala lokuqengqeleka, ukuze umbhobho wensimbi we-lsaw awusekho umzimba we-isotropic kwinqanaba elithile; amaqamza, iintanda kunye nokukhululeka okwenziwa ngexesha lokugalela nako kunokudityaniswa phantsi kobushushu obuphezulu kunye noxinzelelo.

Ukungalungi kombhobho wentsimbi ye-lsaw
1. Uxinzelelo olushiyekileyo olubangelwa kukupholisa okungalinganiyo. Uxinzelelo olushiyekileyo luxinzelelo lwe-self-phase equilibrium phantsi kokungabikho kwamandla angaphandle. Intsimbi eshushu eqengqelekayo yamacandelo ahlukeneyo inoxinzelelo olushiyekileyo olunjalo. Ubukhulu becandelo lentsimbi jikelele, ubukhulu bexinzelelo olushiyekileyo. Nangona uxinzelelo olushiyekileyo luzilungelelanisa, lusenempembelelo ethile ekusebenzeni kwamacandelo ensimbi phantsi kwamandla angaphandle. Ngokomzekelo, inokuba nemiphumo emibi kwi-deformation, ukuzinza, kunye nokumelana nokukhathala.

2. Emva kwe-welding, i-non-metallic inclusions ngaphakathi kwipayipi yensimbi ye-lsaw igxininiswe kwiinqununu ezincinci, kwaye kwenzeka i-delamination phenomenon. I-delamination ithoba kakhulu iipropathi zombhobho wentsimbi ye-lsaw kwicala lobunzima, kwaye inokuncipha kumthungo we-weld. Ukukrazuka kwe-Interlaminar kwenzeka. Uxinzelelo lwendawo olubangelwa yi-weld shrinkage luhlala lufikelela amaxesha amaninzi isivuno sesivuno, esikhulu kakhulu kunobunzima obubangelwa ngumthwalo.
