Xa kufikwa kwi-MIG welding, kubalulekile ukuba abashiseli abatsha baqale ngeziseko ezisisiseko zokuseka isiseko esiluqilima sempumelelo.Inkqubo ngokuqhelekileyo ixolela, yenza kube lula ukufunda kune-TIG welding, umzekelo.Iyakwazi ukuwelda iintsimbi ezininzi kwaye, njengenkqubo eqhubekayo yokutyiswa, inika isantya esikhulu kunye nokusebenza kakuhle kunentonga yokuwelda.
Kanye kunye nokuziqhelanisa, ukwazi ezinye iinkcukacha eziphambili kunokunceda abatsha abatshisayo baqonde ngcono inkqubo ye-MIG ye-welding
Ukhuseleko lwe-Welding
Elona qwalaselo lokuqala lwabashiseli abatsha kukhuseleko lwe-welding.Kunyanzelekile ukuba ufunde kwaye ulandele zonke iilebhile kunye neZikhokelo zoMnini wesixhobo ngononophelo phambi kokufakela, ukusebenza, okanye ukusevisa izixhobo zokuwelda.Iiwelders kufuneka zinxibe ukhuseleko lwamehlo olufanelekileyo ukuphepha ukutsha kwe-arc flash kunye neentlantsi.Ngalo lonke ixesha unxibe iiglasi zokhuseleko kunye nesigcina-ntloko se-welding ukuya kwinqanaba elifanelekileyo lomthunzi.Isinxibo esifanelekileyo sokuzikhusela sikwabalulekile ekukhuseleni ulusu ekutshisweni ngumbane kunye nokutsha.Oku kuquka:
· Izihlangu zesikhumba okanye iibhutsi.
· Isikhumba okanye iiglavu ze-welding ezixhathisa amadangatye
· Ibhatyi ye-welding engatshiyo okanye imikhono ye-welding
Ukungena komoya okwaneleyo kukwayinto ebalulekileyo yokhuseleko.Abashiseli kufuneka bahlale bengayigcini intloko kwi-weld plume kwaye baqiniseke ukuba indawo abalufake kuyo inomoya owaneleyo.Kusenokufuneka uhlobo oluthile lokutsalwa komsi.Imipu yokukhupha i-Fume esusa i-exhaust kwi-arc nayo iluncedo, kwaye iyasebenza kakhulu xa kuthelekiswa nokubanjwa komgangatho okanye isilingi.
Iindlela zokutshintshela i-welding
Ngokuxhomekeke kwisiseko semathiriyeli kunye negesi ekhuselayo, i-welders inokutshisela ngeendlela ezahlukeneyo zokuhambisa i-welding.
Isekethe emfutshane iqhelekile kwizixhobo ezibhityileyo kwaye isebenza ngesantya esisezantsi se-welding kunye nesantya sokutya kocingo, ngoko ke iyacotha kunezinye iinkqubo.Kwakhona kuthanda ukuvelisa i-spatter efuna ukucocwa kwe-post-weld, kodwa ngokubanzi, yinkqubo elula ukuyisebenzisa.
Ukudluliselwa kweglowubhu kusebenza kwizantya eziphezulu zefidi zocingo kunye nombane we-welding kunesekethe emfutshane kwaye isebenzela ukuwelda ngocingo olune-flux-cored wire kunye ne-100% ye-carbon dioxide (CO2) (jonga iinkcukacha kwi-CO2 kwicandelo elilandelayo).Ingasetyenziswa kwi-1/8-intshi kunye nezixhobo ezisisiseko ezityebileyo.Njengokuwelda kwe-MIG yesekethe emfutshane, le mowudi ivelisa i-spatter, kodwa yinkqubo ekhawulezayo.
Ukutshintshwa kwe-spray kunika i-arc egudileyo, ezinzileyo, eyenza ibe nomtsalane kubashicileli abaninzi abatsha.Isebenza kwi-welding ephezulu kunye ne-voltage, ngoko iyakhawuleza kwaye inemveliso.Isebenza kakuhle kwizinto ezisisiseko eziyi-1/8 intshi okanye ngaphezulu.
Irhasi yokukhusela i-welding
Ukongeza ekukhuseleni i-weld pool kwi-atmosfera, uhlobo lwegesi yokukhusela esetyenziselwa ukuwelda i-MIG ichaphazela ukusebenza.Ukungena kwe-weld, ukuzinza kwe-arc kunye neempawu zomatshini zixhomekeke kwigesi yokukhusela.
Ikhabhon diokside ethe ngqo (CO2) inikezela ngokungena kwe-weld enzulu kodwa ine-arc engazinzanga kunye nesitshizi esingaphezulu.Isetyenziselwa ukuwelda i-MIG yesekethe emfutshane.Ukongeza i-argon kumxube we-CO2 kuvumela ukusetyenziswa kokudluliselwa kwesitshizi kwimveliso ephezulu.Ibhalansi ye-75% ye-argon kunye ne-25% iqhelekile.
Ngaphandle kwezinto ezisisiseko
Kanye kunye nokuziqhelanisa, ukwazi ezinye iinkcukacha eziphambili kunokunceda abatsha abatshisayo baqonde ngcono inkqubo ye-MIG ye-welding.Kwakhona kubalulekile ukuzazi izixhobo, kuquka imipu ye-MIG yokuwelda kunye ne-welding liners.Ukuqonda indlela yokukhetha nokugcina esi sixhobo kunokuya kude ekusekeni ukusebenza kakuhle kwe-welding, umgangatho kunye nemveliso.
