1. Ke hobane'ng ha ho na le mapetsong a flange ka mor'a ho cheselletsa
Ha ho etsoa lisebelisoa tsa lisebelisoa, ha flange ea tšepe e sa hloekang le silinda li cheselitsoe, ho tla ba le mapetsong a molaleng oa flange, eseng ka seam sa welding.Bothata ke bofe?Ke hobane’ng ha ho e-na le boemo bo joalo?Pele ho tsohle, a re hlahlobeng mabaka a mapetsong a chesang.
Mapetsong a chesang ke mapetsong a hlahisoang sethaleng sa mocheso o phahameng nakong ea pholileng ea weld, haholo-holo ka tšepe ea weld, le chelete e nyenyane sebakeng se haufi sa seam.E ka aroloa ka mapetsong a crystallization (solidification), mapetsong a liquefaction le mapetsong a polygonal.Mapetsong a kristale ke mofuta o atileng haholo, haholo-holo ka litšepe tsa litšepe tsa k'habone tse nang le likarolo tse ngata tse sa hloekang (S, P, Si le C), litšepe tse se nang mokhahlelo o le mong oa austenitic, aluminium le lialloys tsa eona le meaho e meng e cheselitsoeng.Lintlha tse ka sehloohong tse susumetsang ke khatello ea maikutlo ea ho tjheseletsa, sebaka se tlaase sa ho qhibiliha eutectic (lik'hemik'hale tsa tšepe ea weld), tekanyo ea ho futhumala ho feteletseng ha lenonyeletso le kopantsoeng (ts'ebetso).
2.How to qoba ho Hot Cracks
Ho latela linepe, tšepe e sa hloekang ea 304 e na le polasetiki e matla.Haeba e le flange e entsoeng, litlhoko tsa ts'ebetso ea welding li batla li hlephile, 'me mapetsong hangata ha a bakoe.Haeba e le ho lahla, boemo bona bo atisa ho etsahala.Kahoo, ka ts'ebetso, re qoba mapetsong a mosebetsi joang?Mehato ea ho fokotsa tloaelo ea ho phatloha ho chesang e kenyelletsa:
1) Fokotsa litaba tsa lintho tse sa hloekang tse kang S le P ka thepa.
2) Ho eketsa ka nepo tekanyo ea Mn/S ho ka nka sebaka sa Fe ea Fe-FeS e tlaase-qhibiliha eutectic ho theha MnS e nang le ntlha e qhibilihisang ea 1620Co, ka tsela eo ho ntlafatsa khanyetso ea crack ea weld.
WC=0.10~0.12%, WMn=2.5% pele e sebetsa

3) Sebelisa mekhoa le lits'ebetso tse nepahetseng tsa welding ho laola ho kenya matla le ho fokotsa mocheso o feteletseng oa weld.
4) Eketsa Ti, Mo, Nb kapa likarolo tse sa tloaelehang tsa lefats'e ho lisebelisoa tsa welding ho thibela nts'etsopele ea lijo-thollo, ho hloekisa lijo-thollo, le ho ntlafatsa ts'ebetso haholo.
