Bakeng sa litšepe tse nang le sebopeho se teteaneng sa poleiti le lintho tse ling tse matlafatsang pula, mapetsong a hlahang likarolong tse mahoashe tsa sebaka se amehileng ke mocheso nakong ea khatello ea maikutlo kalafong ea mocheso kapa tšebeletso ka mocheso o itseng o bitsoa mapetsong a futhumatsang. Mapetso a futhumatsang hangata a hlaha likarolong tse mahoashe tsa sebaka se anngoeng ke mocheso oa litšepe tse matla tse tlase tsa alloy, litšepe tse sa keneleng mocheso oa pearlitic, litšepe tse se nang mochini tsa austenitic le li-alloys tse ling tse thehiloeng ho nickel.

Mapetso a batang

Mapetso a batang ke mofuta o tloaelehileng oa mapetsong a hlahisoang ka ho cheselletsa, a hlahisoang ha mocheso o pholile ho fihlela mocheso o tlase ka mor'a ho cheselletsa. Mapetsong a batang haholo a hlaha sebakeng sa tjheseletsa se amehang sebakeng sa tšepe ea alloy e tlase, tšepe ea motsoako o mahareng, k'habone e mahareng le tšepe e phahameng ea khabone. Maemong a motho ka mong, joalo ka ha ho chesetsoa litšepe tse matla a holimo-limo kapa li-alloys tse itseng tsa titanium, mapetsong a batang a boetse a hlaha holim'a tšepe ea weld.
