Oomatshini bokuwelda intonga ye-aluminiyam badume ngokukwazi kwabo ukwenza iiwelds ezinamandla nezithembekileyo. Nangona kunjalo, umba omnye oqhelekileyo onokuchaphazela umgangatho wale welds yi-yellowing ye-welding surfaces. Oku kutyheli, okuhlala kubangelwa yi-oxidation, kunokubeka esichengeni ukuthembeka kwee-welds. Kweli nqaku, siza kuphonononga iindlela zokujongana nokuthintela ukutyheli komphezulu we-welding kumatshini wokuwelda ngentonga ye-aluminium.
1. Ukulungiselela Izinto Ezifanelekileyo
Ukuthintela ukutyheli kuqala ngokulungiselela izinto ezifanelekileyo. Qinisekisa ukuba iintonga ze-aluminiyam eziza kudityaniswa zicocekile kwaye azinangcoliseko ezifana nobumdaka, igrisi, okanye i-oxidation. Coca ngokucokisekileyo umphezulu wentonga usebenzisa iindlela ezifanelekileyo zokucoca, ezifana nebrashi okanye ukucocwa kweekhemikhali, ukususa nakuphi na ukungcola okunokukhokelela kumbala.
2. Umoya oLawulwayo
Enye indlela esebenzayo yokuthintela ukutyheli ngexesha le-welding kukudala umoya olawulwayo ojikeleze indawo ye-welding. Oku kunokufezekiswa ngokusebenzisa igesi ye-inert, efana ne-argon, ukukhusela iindawo ze-welding kwi-oksijeni ye-atmospheric. Ukukhusela igesi engasebenziyo kuthintela i-oxidation kwaye inceda ukugcina umbala wendalo we-aluminium.
3. Ukufudumala
Ukufudumeza iintonga ze-aluminiyam phambi kwe-welding kunokunceda ukunciphisa ukutyheli. Ngokunyusa ngokuthe ngcembe iqondo lobushushu leentonga, ukufudumala kwangaphambili kunciphisa ukwanda okukhawulezayo kunye nokucutha okungakhokelela kwi-oxidation yomhlaba. Ikhuthaza inkqubo ye-welding elula, ukunciphisa amathuba okuba phuzi.
4. IiParameters zeWelding ezifanelekileyo
Iiparamitha ze-welding, kubandakanywa okwangoku, uxinzelelo, kunye nexesha le-welding, lidlala indima ebalulekileyo ekuthinteleni ukuphuzi. Ukusebenzisa iiparamitha ezichanekileyo kwiintonga ezithile ze-aluminiyam ezidityanisiweyo ziqinisekisa ukuhanjiswa kobushushu okusebenzayo kunye nokunciphisa umngcipheko we-oxidation. Qhagamshelana neengcebiso zomenzi kwiiparamitha ezifanelekileyo ze-welding.
5. Ukucocwa kwePost-Weld kunye noNyango
Emva kweweld, kubalulekile ukucoca kunye nokuphatha imiphezulu weld ngokukhawuleza. Susa nayiphi na i-flux eyintsalela okanye izingcolisi usebenzisa iindlela ezifanelekileyo zokucoca. Emva koko, cinga ukusebenzisa unyango lwe-post-weld, njengesisombululo esikhethekileyo sokucoca i-aluminium okanye i-coating yokukhusela, ukukhusela i-oxidation eyongezelelweyo kunye ne-yellowing.
6. Amanyathelo oKhuselo
Sebenzisa imilinganiselo yokukhusela ukukhusela iindawo zokuwelda kumoya ojikelezayo ngexesha lenkqubo ye-welding. Oku kunokubandakanya ukusetyenziswa kwamakhethini e-welding okanye izikhuselo ukwenza umqobo onciphisa ukubonakaliswa kwe-oxygen. Ukugcina indawo ye-welding ikhululekile kwiidrafti kunokunceda ukugcina indawo ye-welding ezinzileyo.
7. Ukugcinwa kwamaxesha ngamaxesha
Ukuhlola rhoqo kwaye ugcine umatshini welding, kubandakanywa i-electrodes kunye namacandelo entloko ye-welding. Nakuphi na ukunxiba okanye umonakalo kula macandelo kunokukhokelela kwi-welding engahambelani kunye nokunyuka kwe-oxidation. Ukujongana nale miba ngokukhawuleza kunganceda ukuthintela ukutyheli.
Ukuqukumbela, ukujongana nokuthintela i-yellowing ye-welding surfaces kwi-aluminium rod butt welding machines ifuna ukudibanisa ukulungiswa kwezinto ezifanelekileyo, i-atmospheres elawulwayo, ukushisa kwangaphambili, kunye nokubambelela kwiiparitha ezifanelekileyo ze-welding. Ukongezelela, ukucocwa kwe-post-weld kunye nonyango, kunye nemilinganiselo yokukhusela kunye nokugcinwa kwesiqhelo, ngamanyathelo abalulekileyo okugcina ingqibelelo kunye nokubonakala kwee-welds. Ngokulandela olu qheliselo, unokuqinisekisa ukuba imisebenzi yakho ye-aluminiyam yentonga ye-welding ivelisa iiwelds ezikumgangatho ophezulu ezinombala omncinci.
