Ukuba i-arc manual, okokuqala, nikela ingqalelo ukwahlula intsimbi etyhidiweyo kunye nokwaleka. Qwalasela idama elinyibilikisiweyo: ulwelo olumenyezelayo yintsimbi enyibilikisiweyo, into edada phezu kwalo kwaye impompoze kukwaleka.
Xa i-welding, qaphela ukuba ungavumeli ukuba i-coating idlule intsimbi etyhidiweyo, ngaphandle koko kulula ukufumana i-slag, kwaye kufuneka ulawule isibambo se-welding ngesandla ukulungelelanisa i-angle yentonga ye-welding.
Kwakhona, ukuba uvakalelwa kukuba ubuchule bulungile, ungasebenzisa i-current ephezulu, kuba umsinga ophakamileyo unokwahlula ngcono i-coating kwintsimbi etyhidiweyo, kwaye i-welding iya kubonakala ngakumbi, kodwa kufuneka ukwazi ukuyilawula. Umjelo we-welding othe nkqo uncinci kune-welding flat, kwaye i-current of overhead welding incinci kune-welding ethe nkqo.
Xa udibanisa, fumana i-posture ekhululekile kwaye ekwazi ukugqiba i-weld ngexesha elinye, kwaye ufunde ukusebenzisa isandla sakho ukulawula isibambo se-welding. Ukuba i-carbon dioxide welding, into yokuqala okumele uyibeke ingqalelo kukuhlala uqaphela i-pool etyhidiweyo ngexesha lenkqubo ye-welding, kwaye kungcono ukusebenzisa indlela yokulawula enye, kwaye izinga lokuhamba kwegesi lihlala li-18-20. Ukuba akukho lawulo lobumbano, kufuneka luhlengahlengiswe ngokwenkqubo ye-welding. Ukuba ucingo lwe-welding aluncibiliki okanye aluncibiliki kakuhle, i-voltage kufuneka ilungiswe phezulu, okanye i-current kufuneka ithotywe. Ukuba ucingo lwe-welding luyancibilika kumathontsi amakhulu okanye indawo enyibilikayo yomthamo omkhulu kakhulu, oko kuthetha ukuba i-voltage inkulu kakhulu.
Ukuba i-electrode ye-tungsten, ifana ne-oxygen welding, kodwa kwakhona qwa lasela ukuba ubude bokwandiswa kwe-electrode ye-tungsten akufanele bube bude kakhulu, kwaye ukuma kwentloko ye-tungsten electrode kufuneka kugcinwe. Qaphela ukuba i-welding yombane ayikwazi ukusetyenziswa kwiindawo ezinomoya, eziya kuba nefuthe elikhulu kumgangatho we-welding. Ukucoceka kwe-weldment kufuneka kuqinisekiswe kwaye ukhuseleko kufuneka luthathelwe ingqalelo.
Ingundoqo kukuba: lawula i-melting pool kwaye ugcine i-melting pool kwi-elliptical shape phantsi kwayo nayiphi na imeko. Emva koko ugqibile ukuwelda! Kufuneka uyazi ukuba yeyiphi intsimbi enyibilikisiweyo kwaye yeyiphi eyokugquma. Oku kusisiseko. Okokuqala, kufuneka wazi ukuba yeyiphi intsimbi enyibilikisiweyo kwaye yeyiphi i-coating. Oku kusisiseko. Emva kokwazi intsimbi etyhidiweyo, kunokuthiwa uqale ufunde i-welding yombane. Yonke into isekelwe kwesi siseko.
I-angle ayifuni ukulandela ii-degrees ezingama-45, sonke siyayazi, kodwa ichaphazeleka ngezizathu ezinenjongo, ezifana nobukhulu bangoku. indawo weldments, etc. Ukunyamekela nje intsimbi etyhidiweyo kwaye ulawule umthamo pool kwaye kuya kulunga. Eyona nto ibalulekileyo kukuweld ngaphezulu! I-welder efanelekileyo ayikwazi ukuqeqeshwa ngobusuku. Kuthatha iintonga zokuwelda ezininzi ukufumba!
I-Xinfa mig welding inomgangatho obalaseleyo kunye nokuqina olomeleleyo, ngeenkcukacha, nceda ujonge: https://www.xinfatools.com/mig-welding-toches/
