Iinkcukacha zeMveliso

Iithegi zeMveliso

Intonga yentsimbi yokugalela isoloko isetyenziselwa ukusombulula iqokobhe le-injini, umzimba wokugquma, isiseko somatshini, amazinyo okuphosa avela ngokuqhekeka kwevili, ukuqhekeka, ukunxiba, iingxaki zokugalela umngxuma.Ngenxa yomxholo wekhabhoni ephezulu, isakhiwo esingalinganiyo, amandla aphantsi kunye neplastiki ephantsi, i-electrode yensimbi ephosiweyo yinto engafanelekanga ye-weldability, elula ukuvelisa iintanda ngexesha le-welding, kunzima ukuyinqumla.Ukuze kuphunyezwe iziphumo ezanelisayo kwi-welding kunye nokulungiswa kwe-welding yentsimbi etyhidiweyo, kubalulekile ukunikela ingqalelo "kwizinto ezintathu kunye nenkqubo yeenxalenye ezisixhenxe", kungekhona nje ukukhetha intonga ye-welding, kodwa kunye nokuthatha indlela efanelekileyo yokulungisa i-welding.
Inkqubo ye-welding elandelayo iyanconywa njengesalathiso se-welding yentsimbi kunye nokulungiswa kwe-welding: 1, okokuqala susa iindawo ze-welding ze-sludge, isanti, amanzi, i-rust kunye nezinye i-debris;Ukongeza, i-carbon-poor layer kunye ne-oxide layer kumphezulu we-iron castings esebenza phantsi kobushushu obuphezulu kunye nokusingqongileyo komphunga ixesha elide kufuneka kususwe.2. Ngokwemilo kunye nohlobo lwesiphene lwenxalenye edibeneyo, amanyathelo okulungiselela afana nokuvulwa kwe-groove, ukuchithwa kokuthintela ukuchithwa komngxuma kunye nemodeli ye-pool etyhidiweyo yenziwa.3. Kumalungu adinga i-welding ebandayo, yitshise ngaphambili kwi-500-600 ° C, khetha i-welding efanelekileyo yangoku, i-welding eqhubekayo, gcina ubushushu be-preheating ngexesha lenkqubo ye-welding, gubungela izinto zokugquma ezifana ne-asbestos powder ngokukhawuleza emva kwe-welding, kwaye uzivumele. pholisa ngokucothayo, ukuze kuphuculwe ukumelana nokuqhekeka kwayo kunye nokusebenza kokucubungula.4. Kwiziqwenga zomsebenzi we-welding obandayo, thintela isiseko sesinyithi sokunyibilika kakhulu, ukunciphisa ukuthambekela komhlophe, ukuthintela ukugxininiswa kobushushu obuninzi, okukhokelela kuxinzelelo olugqithisileyo, i-current encinci, i-arc emfutshane kunye ne-welding pass welding kufuneka isetyenziswe ngokusemandleni. ubude bepasi nganye akufunekanga budlule kwi-50mm) .Kwangoko emva kokuwelda isando weld ukuphumza uxinzelelo ukuthintela ukuqhekeka, de iqondo lobushushu lehla ukuya 60 degrees C ngaphantsi kwenye weld.5, nikela ingqalelo kumngxuma we-arc xa uvala, ukuze uthintele i-arc yokuvala i-crack.
