Medium carbon steel hangata e bua ka carbon content e ka bang 0.25 ho 0.60% carbon steel.Manual arc welding ea carbon steel casting le welding ea likarolo tsa mantlha ka tsela e latelang:

(1) Litšepe tse haufi le sebaka sa weld se atisang ho ba le polasetiki e tlaase ea lisele tse thata.Ha carbon content e phahame, botenya ba poleiti, mokhoa o moholo oa ho thatafala.Weldment stiffer, pholiso e potlakileng le khetho ea melamu ha se nako, e tloaetseng ho phatloha ho batang.

(2) Kaha tšepe ea motheo e ile ea qhibiliha karolong ea pele ea karo-karolelano ea tšepe ea weld e ka bang 30%, kahoo ha carbon content ea weld e phahame, sephetho se bonolo ho cheselletsa tšepe e chesang le ho phunyeha ho batang.

Mehato e nkuoeng ke ho chesetsoa ha tšepe ea khabone

(1) Haeba ho khoneha, khetha li-electrode tse tlaase tsa haedrojene.Li-electrode tse joalo le khanyetso e phahameng ea ho hanyetsa serame ho hanyetsa mocheso oa ho phatloha ha mocheso.Maemong a motho ka mong, ka ho laola ka thata mocheso oa preheating le ho fokotsa phokotso ea tšepe e kenang weld carbon content le mehato e meng ea ts'ebetso, tšebeliso ea electrode ea mofuta oa calcium ilmenite e ka boela ea fumana liphello tse khotsofatsang.Ha matla a tjheseletsa manonyeletso le tšepe botlaaseng ha e hloke nako e lekanang lokela ho sebelisoa ka tlaase-matla tsa motheo tlaase li-electrode haedrojene.Polasetiki e joalo ea Weld Weld, e hlahisa ho phatloha ho batang le ho phatloha ha mocheso ho seng kotsi haholo.

(2) Preheat mehato e ka sehloohong ea thekenoloji ho tjheseletsa le ho lokisa welding ea carbon steel, haholo-holo botenya ba tjheseletsa, ho tiea ho hoholo, ho futhumala molemong oa ho fokotsa boima bo boholo ba sebaka se amehileng ke mocheso le ho thibela ho phatloha ho batang, 'me ho ka ntlafatsa. polasetiki e kopaneng.Kakaretso ea ho futhumala le ho futhumatsa ho loketseng ho boetse ho fokotsa khatello ea masala ea post weld.The content carbon ea fapaneng tjheseletsa carbon tšepe tjheseletsa preheat mocheso le ha ho melao junifomo.Sena ha se feela hobane khetho ea mocheso preheating e khethoa ke carbon content ea eleketrode, empa hape angoa ke lintlha tse ling, tse kang boholo le botenya ba tjheseletsa, mofuta tjheseletsa, mekhahlelo tjheseletsa le ho satalla ha sebopeho le. joalo-joalo.
