1. Ingxelo engemvelaphi
Iimfuno zokwenziwa kwemibhobho yangaphambili kubunjineli be-offshore kunye ne-petrochemical industry iphezulu kakhulu, kwaye umyinge womsebenzi mkhulu kakhulu. Isiseko se-TIG se-welding manual kunye ne-MIG yokuzaliswa kwe-welding kunye nokugubungela kuyasetyenziswa, kodwa umgangatho kunye nokusebenza kakuhle akufanelekile. Eli phepha lamkela inkqubo entsha ye-welding-high-efficiency hot wire welding ye-TIG, ukuphumeza i-TIG base welding, i-welding yokugcwalisa kunye ne-welding yokugubungela, kwaye iphumelele i-MIG ye-welding high-efficiency welding indlela yokubuyisela indlela yendabuko. Ngolu vavanyo, iimpawu zomatshini zophando zibonakaliswe ukuba ziyasebenza kwaye zisetyenziswe ngempumelelo kwishishini.
Injongo yophando
Okwangoku, inkqubo ye-welding yendabuko isebenzisa i-TIG ye-welding manual kwisiseko, i-welding manual okanye i-MIG ye-welding, i-arc welding ephantsi kwamanzi kunye nezinye iindlela ezininzi zokuzalisa kunye nokugubungela ukuphucula ukusebenza kakuhle kwe-welding. Nangona kunjalo, ezi ndlela zokuzalisa kunye nokugubungela akulula ukufikelela kwi-welding ngokuzenzekelayo, ayifanelekanga kwiidamitha ezahlukeneyo zepayipi, kulula ukuvelisa iziphene ze-welding, kwaye izinga lokupasa umgangatho we-welding lilinganiselwe yinqanaba lokusebenza kwabasebenzi.
Xa kuthelekiswa nokuwelda eqhelekileyo TIG, intambo eshushu TIG welding yongeza unikezelo lwamandla ngocingo olushushu oluhlukeneyo ukutshisa intambo yokuwelda ngesiseko socingo olubandayo lwemveli, kwaye kwandisa isantya sokunyibilika kwentambo yokuwelda ngaphandle kokutshintsha amandla omgca we-welding. Ngale ndlela, i-arc ye-welding ebonelelweyo idinga kuphela ukuchitha amandla amancinci ukunyibilikisa ucingo lwe-welding, ngaloo ndlela iphucula ukusebenza kakuhle kwemveliso ye-welding.
I-high-efficiency eshushu i-TIG ingaphezulu kwamaxesha angama-5 ngaphezu kwe-TIG eqhelekileyo, xa kuthelekiswa nesantya se-MIG se-welding, kwaye izinga lokubeka linyuswe ukusuka kwi-0.3 ~ 0.5kg / h ukuya kwi-2 ~ 4kg / h. Itekhnoloji ye-TIG yocingo olushushu lwasekhaya ikwinqanaba elimileyo kwaye ikude nokufikelela kwi-welding esebenzayo nekumgangatho ophezulu. Ukusebenza kwenkqubo ye-welding ye-TIG yangaphandle yocingo olushushu aluzange luphuculwe kakhulu kwaye alukwazi ukufikelela ekusebenzeni kwe-MIG welding. Ke ngoko, kungxamisekile kwaye kubalulekile ukuphuhlisa inkqubo ye-TIG yocingo olushushu olusebenzayo.
