Ukulawula eyakhoumatshini wokuwelda indawokuthetha ukwazi indlela yokuphatha iintsimbi ezahlukeneyo. Imathiriyeli nganye, ukusuka kwintsimbi engatyiwayo ukuya kwi-aluminiyam, ifuna indlela ekhethekileyo yeentsimbi eziqinileyo nezicocekileyo. Nasi isikhokelo esisebenzayo sokuwelda iintsimbi ezine eziqhelekileyo.
Intsimbi engatyiwa: Ulawulo lobushushu oluchanekileyo
Insimbi engenasici ine-conductivity ephantsi kwaye igcina amandla kumaqondo okushisa aphezulu, efuna ukulawulwa kokushisa ngononophelo.
1.Iisetingi ezingundoqo:Sebenzisa langoku elisezantsi (8–10 kA) kunye nexesha elifutshane weld (15–30 ms).
2.Ingcebiso ye-Electrode:Sebenzisa idome{0}}uhlobo lweeelectrode zobhedu zechromium zirconium.
3.Indlela:Umsebenzi ombini- wepulse unceda ukucaphuka indawo ye weld, ukunciphisa umngcipheko wokuqhekeka.
IAluminiyam: Imijikelo yangoku kunye nokuKhawuleza
I-Aluminiyam iqhuba ubushushu ngokukhawuleza kwaye yenza umaleko we-oxide ochasayo, ebiza inkqubo enamandla, ekhawulezayo.
1.Iisetingi ezingundoqo:Umbane ophezulu (unokufikelela kwi-20-30 kA) ngexesha elifutshane kakhulu (Ngaphantsi okanye ukulingana ne-100 ms).
2.Ingcebiso ye-Electrode:Sebenzisa-ii-electrode zobuso zeradiyasi ezinkulu ezinokupholisa kwamanzi okunamandla.
3.Lungiselela umsebenzi:Coca umphezulu ekunene phambi kokuba welding ukususa umaleko oxide.
Ubhedu kunye ne-Alloys: Amandla agxininisiweyo
Ukuhanjiswa okuphezulu kweCopper kwenza kube nzima ukugxininisa ubushushu obaneleyo.
1.Iisetingi ezingundoqo:Iphezulu kakhulu, igxininise okwangoku; ixesha elifutshane weld.
2.Imfuno yomatshini:A medium -frequency DCumatshini wokuwelda indawoifanelekile kwimveliso yamandla ezinzileyo.
3.Ukhathalelo lweElectrode:Gcina imiphezulu yoqhagamshelwano ye-electrode egudileyo ukunqanda ukuncamathela.
Intsimbi eMild: Inkqubo esemgangathweni
Intsimbi yekhabhoni {{0}ephantsi yeyona nto ixhaphakileyo kwaye iyaxolela koomatshini bokuwelda.
1.Iisetingi ezingundoqo:Imodareyitha yangoku (umz., 8–10 kA) kunye nexesha (umz., imijikelo 3–5).
2.Uxinzelelo:Faka i-electrode force eyaneleyo ukwenza i-nugget eqinile ngaphandle kokugxothwa.
Ukuqukumbela
A umatshini wokuwelda indawoiyaguquguquka, kodwa impumelelo yayo ixhomekeke ekuziqhelaniseni neemfuno zentsimbi nganye. Ngokulunga-iiparamitha zokulungisa kunye nokusebenzisa i-electrode elungileyo, ungafumana iziphumo ezizezona zilungileyo kwintsimbi engatyiwa, ialuminiyam, ubhedu, kunye nentsimbi ephakathi.
