1. Iphepha elenziwe ngegalvanized
Iphepha elifakwe igalvanized kufuneka libe yinto eqhelekileyo ye-welding.Ubushushu be-gasification ye-zinc buphantsi kakhulu kunendawo yokunyibilika kwentsimbi, ngoko ke kulula ukumila kunye nokuwelda ngexesha le-welding.Ngokuqinisekileyo, ngenxa yoku, iphepha le-galvanized liya kuba neziphene ngexesha le-welding.Njengoko i-zinc iqhuma ngokuqhubekayo, umphunga owenziweyo uya kungena kwi-weld ukwenza iipores okanye ii-undercuts.Ifanelekile kwi-laser welding.
2. Intsimbi engenasici
Sisoloko sisiva ngezinto zentsimbi engatyiwayo.Izinto zokuwelda ngokubanzi ziquka intsimbi ye austenitic stainless, ferritic stainless steel, kunye martensitic steel stainless.
1. Austenitic steel stainless
I-Austenitic steel stainless inentsebenzo engcono ye-welding, i-conductivity encinci ye-thermal kodwa izinga eliphezulu lokufunxa.Xa isetyenziswe kwi-welding ye-laser, isantya se-welding sikhawuleza kwaye igalelo lobushushu lincinci.I-Austenitic steel stainless isetyenziswa kakhulu kwi-Cr Ni series ye-welding steel stainless steel, kwaye i-laser welding isetyenziswa kakhulu ukuwelda intsimbi engenasici, ithintela ngokufanelekileyo ukuguqulwa kwayo kunye nentsalela.
2. Ferritic steel stainless
Iingenelo zensimbi engenasici ye-ferritic kukuqina kwayo okuphezulu kunye ne-ductility elungileyo.Kwinkqubo ye-welding, impembelelo incinci.Ngokomzekelo, i-austenite kunye ne-martensite inokuqhekeka ngexesha le-laser welding, kodwa i-ferrite iyanciphisa ngokufanelekileyo oku kunokwenzeka.
3. Martensitic steel stainless
I-Martensitic steel stainless inokuba yinto engaqhelekanga kuye wonke umntu, kuba ukusebenza kwayo kuphantsi kakhulu kune-austenitic stainless steel kunye ne-ferritic stainless steel.Ukuqhekeka okubandayo kudla ngokuvela xa i-martensitic stainless steel isetyenziselwa i-welding, kwaye umphumo we-welding awufanelekanga.Ezinye iiprojekthi ze-welding ezineemfuno eziphantsi kunye neendleko zisetyenziswa ngamanye amaxesha, kwaye ukusetyenziswa rhoqo akuphezulu.
3. Intsimbi yentsimbi
Intsimbi ye-alloy nayo ithanda ukuqhekeka okubandayo ngexesha le-welding, kodwa inzuzo yayo kukuba inokuthi ifakwe ngokuthe ngqo kwiqondo lokushisa, kwaye ubunzima bayo buphezulu.Kwezinye izicelo ezineemfuno zobunzima obungqongqo, i-alloy steel welding lukhetho olulungileyo.Kwi-alloy steel welding, i-laser welding isetyenziswa kakhulu.Olunye uthungelwano lwemoto, kwanamalungu e-injini enqwelo-moya, aya kusetyenziselwa ukuwelda intsimbi yealloyi.
