Ziziphi izinto ezichaphazela ukuzinza kwe-arc welding

Izixhobo zokuwelda iXinfa zineempawu zomgangatho ophezulu kunye nexabiso eliphantsi. Ngeenkcukacha, nceda undwendwele:Abavelisi beWelding & Cutting-China Welding & Cutting Factory & Suppliers (xinfatools.com)

Izinto ezichaphazela ukuzinza kwe-arc ye-welding ziquka le miba ilandelayo:

(1) Izakhono zokusebenza ze-Welder kunye nekhono lokulungelelanisa ubude be-arc

Indlela yokusebenza ye-welder yinto ebalulekileyo ekunqumeni ukuzinza kwe-arc. Ngethuba lenkqubo ye-welding, i-welder's gun (i-strip) izitho zomzimba kufuneka zifaneleke kwaye ubude be-arc kufuneka bugcinwe ngokuqhubekayo kangangoko kunokwenzeka. Ngaphandle koko, ukuguquguquka kwangoku kwe-welding okanye ukuphazamiseka kwe-arc kuya kwenzeka. I-angle phakathi kwe-welding wire kunye ne-workpiece, kwaye phakathi kwe-welding gun kunye ne-workpiece, kufuneka ifaneleke ukuvelisa ukungena okufanelekileyo, ukukhusela iziphene ze-welding, kunye nokugcina i-pool etyhidiweyo. Ukwenzela i-welding ngokuzenzekelayo, ubude be-arc bufuneka ukuba bulungelelaniswe ngokuzenzekelayo ukuze kuqinisekiswe ukuba ubude be-arc buhlala buhlala buhleli ngexesha lenkqubo ye-welding, ngaloo ndlela iqinisekisa iiparitha ze-welding rhoqo.

(2)Arc welding power supply

① Iindidi zemithombo yamandla e-arc welding: Imithombo yamandla ye-arc welding ye-DC kunye ne-square wave AC arc welding power sources inozinzo olungcono lwe-arc kune-sine wave AC arc imithombo yamandla welding. Uzinzo lwe-pulse arc welding power supply lungcono, ngoko ke, i-pulse arc welding power supply idla ngokusetyenziswa xa i-welding nge-current encinci.

② Iimpawu zangaphandle ze-arc welding power supply Iimpawu zangaphandle zamandla ombane kufuneka zihambelane neemfuno zokutsha ezizinzileyo ze-arc zendlela ye-welding ehambelanayo. Irhasi yentsimbi yearc welding ngokuqhelekileyo isebenzisa ucingo olucekethekileyo (ububanzi bocingo alukho ngaphezu kwe-3.2mm), kwaye unikezelo lwamandla olucothayo lwangaphandle kufuneka lukhethwe, kungenjalo ukuwelda iGas metal arc welding ene-arc engazinzanga kwaye yangoku ephezulu ngamanye amaxesha. ikwasebenzisa ucingo olungqindilili. Xa usebenzisa ucingo olungqingqwa, kuyafuneka ukuba usebenzise umthombo wamandla oneempawu zangaphandle eziwayo.

③Iimpawu eziguqukayo zobonelelo lwamandla ziquka inguqu yendlela emfutshane. I-CO2 welding arc ngamaxesha athile iyatshisa kwaye icime. Oku kufuna ukuba i-voltage engalayishwanga yonikezelo lwamandla inyuke ngokukhawuleza kwaye i-short-circuit current inyuke ngokumodareyitha.

④Umbane ongekho umthwalo wobonelelo lwamandla we-arc welding. Ukuphakama kwe-voltage yokungabikho komthwalo we-arc welding power supply, kulula ukuqalisa i-arc kunye nokuzinza kwe-arc combustion. Nangona kunjalo, xa i-voltage engekho mthwalo iphezulu kakhulu, iyingozi kukhuseleko lomntu welder.

(3)Welding okwangoku

Inkulu i-welding current, iqondo lokushisa eliphezulu le-arc, linamandla iqondo le-ionization yegesi kunye nokukhutshwa kobushushu kwindawo yekholomu ye-arc, kwaye i-arc iya kuzinza ngakumbi.

(4)Umbane weArc

I-voltage ye-arc kufuneka ihambelane ngokufanelekileyo ne-welding current. Njengoko i-welding yangoku inyuka, i-arc voltage kufuneka inyuke. Xa i-welding current iqhubekayo, ukuba i-arc voltage incinci kakhulu, kulula ukubangela isiphaluka esifutshane; ukuba i-voltage ye-arc inkulu kakhulu, i-arc iya kubetha ngokukhawuleza kwaye itshabalalise ukuzinza kwe-arc welding.

(5) Imeko yendawo yokusebenza, ukuhamba komoya kunye nokuphambuka kwamagnetic

Ukuba umphezulu we-workpiece awucocekanga, njengeoli, i-rust, umswakama, njl. Xa ukuhamba komoya okhuselayo kungazinzi okanye kukho ukuphambuka kwamagnetic, i-arc nayo iya kuzinza.
