Wazi kangakanani ngezinto zokushisela?Ungaphuthelwa inani eliphelele!(I)

1. Ishidi elinothayela

Ishidi elinama-galvanized kufanele libe yizinto ezivame kakhulu zokushisela.Izinga lokushisa le-zinc le-gasification liphansi kakhulu kunendawo yokuncibilika kwensimbi, ngakho-ke kulula ukubumba nokushisela ngesikhathi sokushisela.Yiqiniso, ngenxa yalokhu, ishidi lika-galvanized lizoba namaphutha ngesikhathi sokushisela.Njengoba i-zinc iqhubeka ihwamuka, isitimu esikhiqizwayo sizongena endaweni yokushisela ukuze senze izimbotshana noma ama-undercuts.Ifanele i-laser welding.

2. Insimbi engagqwali

Sivame ukuzwa ngezinto zensimbi engagqwali.Izinto zokushisela ngokuvamile zifaka insimbi engagqwali ye-austenitic, insimbi engagqwali ye-ferritic, nensimbi ye-martensitic.

1. Insimbi engagqwali ye-Austenitic
Insimbi engagqwali ye-Austenitic inokusebenza okungcono kwe-welding, i-thermal conductivity encane kodwa izinga eliphezulu lokumunca.Uma isetshenziswa ku-laser welding, isivinini sokushisela siyashesha futhi okokufaka kokushisa kuncane.Insimbi engagqwali ye-Austenitic isetshenziswa kakhulu emisebenzini yokushisela yensimbi engenasici ye-Cr Ni, futhi i-laser welding isetshenziswa kakhulu ukushisela insimbi engagqwali ye-austenitic, igwema ngempumelelo ukuguga kwayo kanye nezinsalela.

2. Ferritic insimbi engagqwali
Izinzuzo zensimbi engagqwali ye-ferritic ukuqina kwayo okukhulu kanye ne-ductility enhle.Enqubweni yokushisela, umthelela uncane.Isibonelo, i-austenite ne-martensite ingase iqhekeke ngesikhathi sokushiswa kwe-laser, kodwa i-ferrite inciphisa ngempumelelo lokhu kungenzeka.

3. Insimbi engagqwali ye-Martensitic
Insimbi engagqwali ye-Martensitic ingase ixake kuwo wonke umuntu, ngoba ukusebenza kwayo kuphansi kakhulu kunokwensimbi engagqwali ye-austenitic kanye ne-ferritic stainless steel.Ukuqhekeka okubandayo kuvame ukwenzeka lapho insimbi engagqwali ye-martensitic isetshenziselwa ukushisela, futhi umphumela wokushisela awulungile.Amanye amaphrojekthi wokushisela anezidingo eziphansi nezindleko asetshenziswa ngezikhathi ezithile, futhi imvamisa yokusetshenziswa ayiphezulu.

3. Insimbi ye-alloy

Insimbi ye-alloy nayo ijwayele ukuqhekeka okubandayo ngesikhathi sokushisela, kodwa inzuzo yayo ukuthi ingafakwa ngokuqondile ekamelweni lokushisa, futhi ubulukhuni bayo buphezulu.Kwezinye izinhlelo zokusebenza ezinezidingo eziqinile zokuqina, i-alloy steel welding iyisinqumo esihle.Ukuze i-alloy steel welding, i-laser welding isetshenziswa kakhulu.Okunye ukuthunyelwa kwezimoto, ngisho nezingxenye zenjini zendiza, zizosetshenziselwa ukushisela insimbi ye-alloy.
