4. Ingxubevange yeAluminiyam
Njengoko sonke sisazi, i-thermal conductivity ye-aluminium alloys iphezulu kakhulu. Ngaphandle koko, iialloyi ze-aluminiyam nazo zinokubonakala okuphezulu. Ke ngoko, ukuba i-laser welding iyafuneka kwi-alloys ye-aluminium, ukuxinana kwamandla aphezulu kuyafuneka. Ngokomzekelo, uchungechunge oluqhelekileyo lwe-1 ukuya kwi-5 lunokuthi lufakwe nge-laser. Ewe kunjalo, kukwakho amanye amacandelo aguquguqukayo kwi-alloy ye-aluminium, njengephepha legalvanized ngaphambili, ngoko ke akunakuphepheka ukuba umphunga othile ungene kwi-weld ngexesha lenkqubo ye-welding, ngaloo ndlela yenze imingxuma yomoya. Ukongeza, i-viscosity ye-aluminium alloy iphantsi, ngoko sinokuyiphucula le meko ngokuyila ngokubambisana ngexesha le-welding.
5. Ingxubevange ye-Titanium / titanium
I-Titanium alloy nayo yinto eqhelekileyo ye-welding. Ukusebenzisa i-laser welding ukuwelda i-titanium alloy ayinakufumana kuphela iindawo zokuwelda ezikumgangatho ophezulu, kodwa zibe neplastiki engcono. Njengoko izinto ze-titanium zilula kwaye zimnyama kwi-gap eyenziwe yigesi, kufuneka sihlawule ngakumbi kunyango oludibeneyo kunye nokukhusela igesi. Ngexesha le-welding, ingqalelo kufuneka ihlawulwe kulawulo lwe-hydrogen, enokunciphisa ngokufanelekileyo ukulibaziseka kokuqhekeka kwe-titanium alloy kwinkqubo ye-welding. I-Porosity yeyona ngxaki ixhaphakileyo yezixhobo ze-titanium kunye ne-titanium alloys ngexesha le-welding. Nazi ezinye iindlela ezisebenzayo zokuphelisa i-porosity: okokuqala, i-argon enobunyulu obuphezulu kune-99.9% inokukhethwa kwi-welding. Okwesibini, inokucocwa phambi kwe-welding. Okokugqibela, ukucaciswa kwe-welding ye-titanium kunye ne-titanium alloys kufuneka ilandelwe ngokungqongqo kwinkqubo ye-welding. Ngale ndlela, ukuveliswa kwee-pores kunokuphetshwa kwinqanaba elikhulu.
6. Ubhedu
Abantu abaninzi banokungazi ukuba ubhedu luyinto eqhelekileyo kwi-welding. Izinto zobhedu ngokubanzi zibandakanya ubhedu kunye nobhedu olubomvu, oluye lwezixhobo eziphezulu ezichasene nokukhanya. Xa ukhetha ubhedu njengento yokuthungatha, nikela ingqalelo kumxholo we-zinc kuwo. Ukuba umxholo uphezulu kakhulu, ingxaki ye-welding ye-galvanized sheet ekhankanywe ngasentla iya kwenzeka. Kwimeko yobhedu obomvu, ingqalelo kufuneka ihlawulwe kubuninzi bamandla ngexesha le-welding. Kuphela ukuxinana kwamandla aphezulu kunokwanelisa umsebenzi we-welding wobhedu obomvu.
Oku kukuphela koluhlu lwezinto eziqhelekileyo ze-welding. Sazise izixhobo ezahlukeneyo eziqhelekileyo ngokweenkcukacha, ngethemba lokukunceda
