Isisekelo esiyisisekelo se- ukucima ukushisa kwe-induction nokuzithiba kwama-welds

Indlela yokwelapha ukushisa kwe-weld ifaneleka kwikhabhoni ephansi kanye nensimbi ephansi ye-alloy eshiselwe ipayipi ye-weld yokushisa, futhi isimiso sayo esiyisisekelo simi kanje.

(1) Ukucwenga izinhlamvu zensimbi yokushisela. Izinga lokushisa eliphezulu lokuhlanganisa i-welding lenza izinhlamvu ze-weld kanye nendawo ethinteke ukushisa zibe mahhadlahhadla, kwehlisa amandla nokuqina kwayo. Ngemuva kokuthi ukushisa kwe-induction kusetshenziselwa ukuphakamisa ngokushesha izinga lokushisa ekushiseni kwe-austenitizing, okusanhlamvu okuhle kutholakala ngokucisha ngokushesha, okuqeda ukugoqa okusanhlamvu kwe-weld futhi kuthuthukise ukusebenza kwayo.

(2) Sebenzisa ukucisha ukushisa okuyinsalela ukwenza ukushisa okuphansi kwe-welding seam ukushisa ukuze kucishwe izinga lokushisa, ngokushesha fafaza ukupholisa amanzi, lapho umphetho wokushisela upholile ukuya ku-200 ~ 300 ° C, yeka ukufafaza ukupholisa kwamanzi, ngalesi sikhathi izinga lokushisa lomthungo wokushisela. kubizwa ngokuthi izinga lokushisa lokuqedwa kokucisha . I-weld ibe isipholiswa emoyeni ukuze ikwazi ukuzibamba, futhi izinga lokushisa lokuzibamba lingama-250 ~ 150 ° C. Lapho i-weld ipholile kusukela ekushiseni kwe-austenitizing quenching kuya ku-200 ~ 300 ° C, kwakheka isakhiwo esixubile se-martensite ne-austenite egciniwe. Uma ukufudumala ekushiseni okuphansi okungu-250 ~ 150 ° C, i-martensite ekushiseni iyabola ukuze kuncishiswe ubulukhuni, kuyilapho i-austenite egciniwe ishintsha ibe yi-bainite noma i-tendered martensite, okwandisa ubulukhuni. Njengomphumela womphumela ohlangene walokhu kwanda nokuncipha, insimbi ye-weld igcina amandla aphezulu kanye nokuqina okuhle.

Ngamafuphi, ngemva kokushisa okusheshayo kanye ne-austenitizing kanye nokucisha, izinhlamvu zensimbi ezishiselwe ziyacwengwa. Ngesikhathi esifanayo, izinga lokushisa lokucisha lokucisha lilawulwa ukuze kugcinwe ukuqina okuhle kwe-weld. Ngemuva kokushisa okuphansi kwezinga lokushisa, kutholakala isakhiwo esihle se-martensite esithambile, ukuze i-weld ibe nokuqina okuphezulu namandla aphezulu. Lona umgomo oyisisekelo wokucisha ukushisa kwe-induction kanye nokuzibamba kwama-welds.
