Kuhlelo lokukhiqizaamapayipi ensimbi aqondile, izinga lokushisa kufanele lilawulwe ngokuqinile, ukuze kuqinisekiswe ukwethembeka kwe-welding.Uma izinga lokushisa liphansi kakhulu, kungase kubangele ukuthi isikhundla sokushisela asikwazi ukufinyelela izinga lokushisa elidingekayo lokushisela.Esimeni lapho iningi lesakhiwo sensimbi lisaqinile, izinsimbi emikhawulweni yomibili kunzima ukungena nokuhlanganisa ndawonye.Uma izinga lokushisa liphezulu kakhulu, kunezinsimbi eziningi esimweni esincibilikisiwe endaweni yokushisela.Ukuthungwa kwalezi zingxenye kuthambile kakhulu, futhi uketshezi oluthile kungase kubangele isimo samaconsi ancibilikisiwe.Lapho amaconsi ensimbi anjalo ewela ngemuva, ayikho insimbi eyanele yokungena phakathi.Futhi lapho kushiselwa, kuzoba nama-welds angalingani ukwenza umgodi wokuncibilika.

Uma izinga lokushisa lokushisela lepayipi lensimbi eliqondile lingalawulwa kahle, lingase libe nomthelela omubi ekuguquleni, ukuzinza, ukumelana nokukhathala, njll.owokuqala usetshenziselwa ukushisa okungenalutho kusuka ekushiseni okujwayelekile kuya ekucutshungulweni kwezinga lokushisa;okokugcina kusetshenziselwa ukushisa kabusha okungenalutho ekushiseni okudingekile kokucubungula ngesikhathi sokucubungula.Ukushisa okungalungile kwepayipi lensimbi yomthungo oqondile kuzoba isizathu sokuvela kwemifantu, ukugoqa kanye ne-migraine endaweni yangaphakathi noma yangaphandle ye-tube engenalutho.
