Intshayelelo: Kutheni le nto ukuWelding amashiti eGati kunguMcelimngeni?
Ngelixa amashiti entsimbi enamaqondo agqwesileyo -okuthintela ukudleka, anika umngeni wokuwelda. I-Zinc ineqondo eliphantsi lokunyibilika (malunga ne-420 degree) kwaye i-vaporize ngokulula ngexesha lenkqubo ye-welding, yenze ii-pores okanye i-spatter, echaphazela umgangatho we-weld. Ngoko ke, xa usebenzisa i-aumatshini wokuwelda indawokumaphepha e-galvanized, uhlengahlengiso oluhambelanayo lwenkqubo kunye nokulungiswa kwezixhobo kufuneka zamkelwe ukuze kuqinisekiswe umgangatho we-welding ozinzile nothembekileyo.
I. I-Zinc Layer Evaporation ekhokelela kwi-Welding Defects
Ngethuba lokufudumeza kwe-welding, i-zinc layer yamaphepha e-galvanized iphuphuma ngokukhawuleza, ivelise inani elikhulu legesi, elinokuthi lenze lula iziphene ezifana ne-pores kunye ne-slag inclusions kwi-weld, ukunciphisa amandla okudibanisa kunye nokutywinwa. Ukunciphisa iingxaki ezinjalo, ngokufanelekileyo ukwandisa i-welding yangoku kwaye unciphise ixesha lokudibanisa ukufezekisa ukudibanisa ngokukhawuleza kunye nokunciphisa ukugcinwa komphunga we-zinc.
II. Ukunxiba okulula kweeNgcebiso ze-Electrode, ezichaphazela ukuzinza kwe-Welding
Izinto ze-Zinc zisabela ngokulula kunye nezixhobo ze-electrode kumaqondo okushisa aphezulu, kubangela i-oxidation ngokukhawuleza okanye ukunamathela kwi-tip ye-electrode, ngaloo ndlela ichaphazela i-conductivity kunye nesicelo soxinzelelo. Ngoko ke, xa usebenzisa i-aumatshini wokuwelda indawokumaphepha e-galvanized, kucetyiswa ukuba kusetyenziswe izinto ze-electrode ezinokumelana ne-corrosion enamandla, njenge-chromium zirconium yobhedu, kunye nokucoca okanye ukubuyisela i-electrodes rhoqo ukuqinisekisa ukuhambelana kwe-welding.
III. Ukwahluka okukhulu kwiNkxaso yoQhagamshelwano, echaphazela uLawulo loBushushu
Ubukho bomaleko owenziwe ngegalvanized buguqula ukuchasana koqhagamshelwano phakathi kwephepha kunye ne-electrode, ekhokelela kubushushu obungazinzanga be-welding, nto leyo echaphazela umgangatho we-welding. Ukujongana nale nto, ukulungelelanisa ngokufanelekileyo uxinzelelo lwe-welding kunye neeparitha zangoku ngokuhambelana nobukhulu bephepha le-galvanized kunye ne-zinc layer ukuqinisekisa igalelo elilinganayo kunye nokulawulwa kokushisa.
IV. I-Welding Spatter egqithisileyo, echaphazela inkangeleko kunye nokusebenza kakuhle
Ngenxa yendawo yokubilisa ephantsi ye-zinc, iigesi eziveliswayo ngexesha lenkqubo ye-welding zinokubangela ukuba i-spatter ibe lula, engachaphazeli nje ukucoceka kwendawo ye-welding kodwa inokubangela umonakalo kwizixhobo kunye nabaqhubi. Izisombululo zale ngxaki zibandakanya ukulungelelanisa imilo ye-electrode, ukuphucula isantya sokuphendula senkqubo yoxinzelelo, kunye nokwamkela iindlela zoxinzelelo olunyathelweyo.
Ukuqukumbela: Ukujongana neNzululwazi ngobunzima bokuWelding amashiti aGalvanized is Key
Isishwankathelo,oomatshini bokuwelda amabalakuba amashiti amazinki ajongana nobunzima obuninzi ngexesha lenkqubo ye-welding, kubandakanywa ukukhuphuka kwe-zinc layer, ukunxiba kwe-electrode, ukuxhathisa okungazinzanga, kunye ne-welding spatter. Ngokulungisa iiparamitha ze-welding, ukukhetha izinto ezifanelekileyo ze-electrode, kunye nokomeleza ukugcinwa kwezixhobo kunye nokulawulwa kwenkqubo, umgangatho we-welding kunye nokusebenza kakuhle kwemveliso kunokuphuculwa ngokufanelekileyo. Ngophuhliso lwetekhnoloji ye-welding ekrelekrele, ikamvaoomatshini bokuwelda amabalakuba amashiti anezinki azakuchaneka ngakumbi kwaye azinze, exhasa uphuhliso oluphezulu{0}}lomgangatho wokwenziwa kwemveliso.
