Imeko yonikezelo

Ukutyunjwa	Uphawu	Inkcazo
Kubanda kugqityiwe (kunzima)	BK(+C)	Iityhubhu azilufumani kunyango lobushushu emva kokumila kwengqele yokugqibela kwaye, ngenxa yoko, zinokuchasana nokonakala
Kubanda kugqityiwe (Kuthambile)	BKW	Unyango lokugqibela lobushushu lulandelwa ngumzobo obandayo obandakanya ukuguqulwa okulinganiselweyo.Ukuqhubela phambili okufanelekileyo kuvumela iqondo elithile lokubumba okubandayo (umzekelo ukugoba, ukwandisa)
Kubanda kugqityiwe (Kuthambile)	(+LC)
Ukubanda kuphelile kunye nokunciphisa uxinzelelo	BKS(+SR)	Unyango lobushushu lusetyenziswa ngokulandela inkqubo yokugqibela yokubumba ebandayo.Ngokuxhomekeke kwiimeko ezifanelekileyo zokucwangcisa, ukwanda koxinzelelo olushiyekileyo olubandakanyekayo lwenza ukuba zombini zenze kunye nomatshini ukuya kwinqanaba elithile.
I-Anealed	GBK(+A)	Inkqubo yokugqibela yokubumba i-Cold ilandelwa yi-annealing kwi-atmosfera elawulwayo.
Iqhelekile	NBK(+N)	Inkqubo yokugqibela ebandayo yokubumba ilandelwa kukufakwa kwe-anneal ngaphezu kwendawo yokuguqula ephezulu kwindawo elawulwayo.

Inkqubo yokuvelisa

Iingenelo

Yomeleza ukuhlolwa kweemveliso kwinqanaba ngalinye lemveliso, lixhotyiswe ngezixhobo zovavanyo ezipheleleyo: uvavanyo lwangoku lwe-eddy olungangonakalisiyo, umatshini wokuvavanya uxinzelelo oluphezulu, umatshini wovavanyo we-universal mechanical tensile, ukugoba umatshini wokuvavanya amaflare, uhlalutyi lococeko, isihlalutyi sentsimbi, njl. Hlangana neempawu zemishini yeemveliso, uvavanyo lwenkqubo yokusebenza, ukubonelela ngesiqinisekiso esinamandla kwiimveliso ezifanelekileyo.
