Izinga lekhwalithi yehook meshzonke izingxenye kufanele ziqinisekise ukuthi impahla, ubude ingxenye ukubekezelelana iphutha kuyinto 1mm.Ngaphambi kokuba ingxenye ivaliwe, kuyadingeka ukuhlola ukuthi iqondile noma cha, ngaphandle kwalokho kufanele iqondiswe.Induku yokushisela noma ucingo lokushisela kufanele kukhethwe olufanele uhlobo lwezinto zokushisela, futhi kufanele kube nesitifiketi sefekthri.
Lapho kushiselwa, ilungu kufanele libekwe endaweni efanele.Lapho ukushisela, amalunga okushisela phakathi kwezingxenye kufanele abe nempilo, i-weld kufanele igcwale, i-welding wave ye-weld surface kufanele ibe iyunifomu, akufanele kube nokulunywa, hhayi ukushisela okugcwele, ukuqhekeka, okusele, isimila sokushisela, ukushiswa, i-arc scratch, umgodi we-arc kanye nezimbotshana yenaliti nezinye iziphambeko, indawo yokushisela akufanele ibe ne-spatter.
Ngemuva kokuphothulwa kwe-welding, i-welding slag kufanele ikhishwe.Ngemva kokushisela nokuhlanganisa izingxenye, kufanele zipholishwe kahle ngamathuluzi aphathwa ngesandla ukuze kubonakale kushelelezi futhi kukhanye.Hlola ikhwalithi yocingo kufanele uqaphele, izinga elingaphezu kwephutha elivumelekile: ukuntuleka kobude nobubanzi be-weld, ububanzi nobukhulu, ukuchezuka komugqa, ukugoba namanye amaphutha, kufanele kulawule ngokuqinile ukuqondiswa kwesihlobo sezinga lesikhundla sokushisela, abaqeqeshiwe. i-rear quasi welding, i-welding heart operation.
I-Weld crack: ukuze kuvinjwe ukuhlaselwa kwe-crack, kufanele ukhethe imingcele ye-welding efanele yezobuchwepheshe kanye nenqubo ye-welding, gwema okwamanje amancane, ungaphumi ngokuzumayo, amalunga e-weld kufanele abe i-lap 10 ~ 15mm, i-welding ayivunyelwe ukunyakaza, shaya i-weldment.I-surface porosity: indawo yokushisela kufanele igezwe futhi ihlanzwe.Khetha i-welding current efanelekile ngesikhathi senqubo yokushisela ukuze unciphise isivinini sokushisela futhi wenze igesi echibini elincibilikisiwe ibaleke ngokuphelele.
