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.
