Ha ho tjheseletsa lipoleiti tsa tšepe tse nang le li-welders tsa maqhubu a mahareng, porosity e ka ba taba e tloaelehileng.Porosity e bolela ho ba teng ha likoti tse nyenyane kapa masoba ka har'a motsoako o cheselitsoeng, o ka fokolisang lenonyeletso le ho fokotsa boleng ba lona ka kakaretso.Sehloohong sena, re tla tšohla litsela tse ling tsa ho rarolla bothata ba porosity ho tjheseletsa lipoleiti tsa tšepe tse nang le li-welders tsa maqhubu a mahareng.
Ntlha ea pele, ke habohlokoa ho etsa bonnete ba hore lisebelisoa tsa welding li behiloe ka nepo.Sena se kenyelletsa ho khetha li-parameter tse loketseng tsa ho tjheseletsa joalo ka hona joale, nako ea welding, matla a elektrode le boholo ba eleketrode.Ho sebelisa li-parameter tse fosahetseng ho ka lebisa ho porosity le mefokolo e meng ka lenonyeletso le cheselitsoeng.
Taba ea bobeli, bokaholimo ba lipoleiti tsa tšepe bo lokela ho hloekisoa hantle le ho lokisoa pele ho tjheseletsa.Litšila leha e le life tse kang mafome, oli, kapa mafura li lokela ho tlosoa ho tiisa hore ho na le sebaka se hloekileng le se boreleli bakeng sa ho cheselletsa.Sena se ka finyelloa ka ho sebelisa li-solvents, borashe ba terata kapa lisebelisoa tse ling tsa ho hloekisa.
Ntlha ea boraro, ho sebelisa mokhoa o nepahetseng oa ho cheselletsa ho bohlokoa ho thibela porosity.Ka mohlala, ho boloka lebelo le loketseng la ho cheselletsa, ho laola matla a electrode le angle, le ho netefatsa hore ho na le tlhophiso e nepahetseng pakeng tsa li-electrode le workpiece ho ka thusa ho thibela porosity hore e se ke ea etsahala.
Ho feta moo, ho khetha lisebelisoa tse loketseng tsa welding ho ka boela ha thusa ho thibela porosity.Bakeng sa tjheseletsa tšepe e sa hloekang, ho kgothaletswa ho sebelisa lithapo tsa welding kapa li-electrode tse nang le khabone e tlase ho fokotsa kotsi ea porosity.
Qetellong, haeba porosity e ntse e etsahala ka mor'a ho kenya ts'ebetsong mehato ena, ho ka 'na ha hlokahala hore u hlahlobe le ho lokisa thepa ea ho cheseletsa kapa ho batla keletso ea setsebi sa welding ho tseba le ho rarolla mathata leha e le afe a ka sehloohong.
Qetellong, porosity ke taba e tloaelehileng ha ho tjheseletsa lipoleiti tsa tšepe tse sa hloekang tse nang le li-welders tsa maqhubu a mahareng, empa e ka thijoa ka ho etsa bonnete ba hore ho hlophisoa ha lisebelisoa hantle, ho lokisoa ha bokaholimo, mokhoa oa ho tjheseletsa, le khetho e ka sebelisoang ea welding.Haeba ho ntse ho e-na le porosity, ho ka 'na ha hlokahala tlhahlobo e eketsehileng le ho lokisoa ho rarolla bothata.
