Sisiphi isizathu se-electrode encangathi ngexesha le-welding

Ukuncamathelwa kwe-Electrode yinto eyenzeka kwi-electrode kunye nenxalenye enamathelayo xa indawo yokuwelda iwelda kunye ne-electrode kunye namalungu enza i-weld engaqhelekanga. Kwiimeko ezinzima, i-electrode ikhutshwa kwaye ukuhamba kwamanzi okupholisa kubangela ukuba iindawo zivuthe.
Kukho izizathu ezine eziphambili zokuncamathela kwe-electrode ngexesha le-welding: iindawo zokusebenza zee-electrode ezimbini azihambelani, iindawo zokusebenza zee-electrode zirhabaxa, uxinzelelo lwe-electrode alwanelanga, kunye nombhobho wamanzi kwindawo yokupholisa yompu we-welding. idityaniswe ngasemva okanye ukujikeleza kwamanzi okupholisa kuvaliwe.

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

1. Iindawo zokusebenza ze-electrode ezimbini azihambelani

Xa iindawo zokusebenza ze-electrodes ezimbini azihambelani, iindawo zokusebenza ze-electrode ziya kuba zidibene kunye neengxenye, ukuchasana koqhagamshelwano phakathi kwe-electrodes kunye namacandelo kuya kwanda, kwaye i-current ye-welding circuit iya kuncipha.

Xa i-current igxininiswe kwindawo yoqhagamshelwano yendawo, kwaye ubuninzi bangoku kwindawo yoqhagamshelwano bukhulu kunobuninzi obukhoyo bomsebenzi we-electrode ngexesha le-welding eqhelekileyo, ubushushu bendawo yoqhagamshelwano buphakama kwiqondo lokushisa elidibeneyo le-electrode. kwaye inxalenye, kunye ne-electrode kunye nenxalenye ziya kuhlanganiswa.

2. Indawo yokusebenza ye-electrode inzima

Indawo yokusebenza ye-electrode ayikwazi ukufakwa ngokupheleleyo kunye nenxalenye, kwaye kuphela ezinye iindawo eziphumayo zidibene nenxalenye. Le meko iya kubangela ukuba iindawo zokusebenza zee-electrode ezimbini zingahambelani, okukhokelela kwii-electrode ezincangathi.

3. Uxinzelelo lwe-electrode olunganelanga

Ukuchasana noqhagamshelwano kuhambelana ngokungafaniyo noxinzelelo. Uxinzelelo olungonelanga lwe-electrode kwandisa ukuchasana koqhagamshelwano phakathi kwe-electrode kunye nenxalenye, kunye nobushushu bokumelana nenxalenye yoqhagamshelwano buyanyuka, ukuze ubushushu bomphezulu woqhagamshelwano phakathi kwe-electrode kunye nenxalenye bunyuke ukuya kwiqondo lokushisa elidibanisayo, ngaloo ndlela lwenza uxhulumaniso phakathi i-electrode kunye nenxalenye.

4. Umbhobho wamanzi we-welding gun yokupholisa i-outlet idityaniswe ngasemva okanye ukujikeleza kwamanzi okupholisa kuvaliwe.

Umbhobho wamanzi we-welding gun yokupholisa i-outlet idibaniswe ngasemva okanye ukujikeleza kwamanzi okupholisa kuvaliwe, ukushisa kwe-electrode kuphakama, kunye ne-electrode kunye nenxalenye inokudityaniswa ngexesha le-welding eqhubekayo.

Ezi meko zine zingentla zinokubangela ukuba i-electrode kunye nenxalenye idityaniswe kwaye idityaniswe, okukhokelela kwisenzeko se-electrode encangathi. Ke, ukuthintela njani ukwenzeka kwezinto ezincangathi ze-electrode?

(1) Fayila intloko ye-electrode ukwenza iindawo zokusebenza zee-electrode ezimbini zihambelane kwaye zingabi naburhabaxa. Inkqubo ye-welding inokukhethwa njengenkqubo yokugaya (akukho mveliso yangoku), kunye neendawo zokusebenza ze-electrode ezimbini zingabonwa ukuba zihambelane ngokudubula i-welding gun.

(2) Kwimeko yokusila, dubula umpu we-welding amaxesha ama-5 ukuya kwali-10 ukwenza imiphezulu yokusebenza yee-electrode ezimbini ukwandisa indawo yokunxibelelana ngaphakathi koluhlu oluchaziweyo lwedayamitha yentloko ye-electrode kunye nokuphucula ukuqina komphezulu.

(3) Fudumeza indawo yokusebenza ye-electrode ngedangatye le-oxyacetylene ukwenza umaleko we-oxide (i-oxide layer) kwindawo yokusebenza ye-electrode, enokunyusa indawo yokunyibilika yendawo yokusebenza ye-electrode kwaye itshabalalise ukuwelda phakathi i-electrode kunye nenxalenye.

(4) Faka isicelo esibomvu esilungiselelwe ngumshiseli kwindawo yokusebenza ye-electrode ukutshabalalisa i-weldability phakathi kwe-electrode kunye nenxalenye.

(5) Lungisa uxinzelelo lwe-electrode kwaye usebenzise iiparamitha ze-welding ngoxinzelelo oluphezulu, ukunikezelwa kwamandla amakhulu kunye nombane omfutshane ngexesha.

(6) Coca umbhobho wamanzi okupholisa rhoqo ukuqinisekisa ukuhamba kwamanzi okupholisa. Oku ngasentla kuyo yonke imilinganiselo enokusombulula ingxaki yokunamathela kwi-electrodes ngexesha le-welding.
