Lapho ushisela amapuleti ensimbi engagqwali anamashisela amabala aphakathi nendawo, ukuqina kungaba yinkinga evamile.I-porosity ibhekisela ekubeni khona kwemigodi emincane noma izimbobo endaweni ehlanganisiwe eshiselwe, engenza buthaka ilunga futhi inciphise ikhwalithi yayo yonke.Kulesi sihloko, sizoxoxa ngezindlela zokuxazulula inkinga ye-porosity ekushiseleni amapuleti ensimbi engenasici anama-welder amabala aphakathi nendawo.
Okokuqala, kubalulekile ukuqinisekisa ukuthi imishini yokushisela ihlelwe ngendlela efanele.Lokhu kuhlanganisa ukukhetha amapharamitha wokushisela afanelekile njengamanje welding, isikhathi sokushisela, amandla e-electrode, nosayizi we-electrode.Ukusebenzisa amapharamitha angalungile kungaholela ku-porosity nokunye ukukhubazeka ekuhlanganyeleni okushiselwe.
Okwesibili, i-welding surface yamapuleti ensimbi engagqwali kufanele ihlanzwe kahle futhi ilungiswe ngaphambi kokushisela.Noma yikuphi ukungcola okufana nokugqwala, uwoyela, noma amafutha kufanele kususwe ukuze kuqinisekiswe indawo ehlanzekile nebushelelezi yokushisela.Lokhu kungafezwa ngokusebenzisa izincibilikisi, amabhulashi ocingo, noma amanye amathuluzi okuhlanza.
Okwesithathu, ukusebenzisa indlela yokushisela efanele kubalulekile ekuvimbeleni i-porosity.Isibonelo, ukugcina isivinini esifanelekile sokushisela, ukulawula amandla e-electrode kanye ne-engeli, nokuqinisekisa ukuhleleka okufanele phakathi kwama-electrode kanye nendawo yokusebenza konke kungasiza ekuvimbeleni ukwenzeka kwe-porosity.
Ngaphezu kwalokho, ukukhetha izinto ezisetshenziswayo zokushisela ezifanelekile nakho kungasiza ekuvimbeleni i-porosity.Ngokushisela insimbi engagqwali, kunconywa ukuthi usebenzise izintambo zokushisela noma ama-electrode anekhabhoni ephansi ukuze unciphise ubungozi be-porosity.
Okokugcina, uma i-porosity isenzeka ngemva kokuqaliswa kwalezi zinyathelo, kungase kudingeke ukuthi uhlole futhi ulungise imishini yokushisela noma ufune iseluleko sochwepheshe wokushisela ukuze ubone futhi uxazulule noma yiziphi izinkinga ezikhona.
Sengiphetha, i-porosity iyinkinga evamile lapho kushiselwa amapuleti ensimbi engagqwali anezindawo zokushisela ama-frequency aphakathi nendawo, kodwa ingavinjelwa ngokuqinisekisa ukusethwa kwemishini efanele, ukulungiswa kwendawo, indlela yokushisela, kanye nokukhetha okusebenzisekayo kokushisela.Uma i-porosity isenzeka, ukuhlolwa okwengeziwe nokulungiswa kungase kudingeke ukuze kuxazululwe inkinga.
