Iziphene zeWeld:Izinkinga ze-Weld ziyindlela embi kakhulu, esetshenziswayo yokugaya imishini isetshenziselwa ukunxephezela, okuholele kumamaki wokugaya, okuholela ebusweni abangalingani, kuthinte ukubukeka.
Indawo engahambelani:Ukuthathwa nokuhamba kuphela kwe-weld kuzodala indawo engalingani futhi kuthinte ukubukeka.
Ukuqhekeka kunzima ukususa:Ukuhamba phambili kokutshala okuphelele, akunakucutshungulwa kwinqubo yazo zonke izinhlobo zokuqhekeka okususiwe, futhi akukwazi ukususa ngenxa yokuklwebheka, ama-splashes we-welding kanye nokunamathela ebusweni bensimbi engenasici, ama-splashes kanye nokunye ukungcola, okuholela ekutheni kube nokungcola kwe-Corlosive abezindaba ngaphansi kwesimo sokugqwala kwamakhemikhali noma ukugqwala kwe-electrochemical nokugqwala.
Okungalingani Ukupholisha nokuPhuku:Ukwelashwa kokushisa kwenziwa ngokukhanyisa kwenziwa ngemuva kokupholisha ngesandla nokupholisha. Kunzima ukufeza umphumela womfaniswano nokungaguquki komthelela wokwelashwa kokuthethelelwa okukhulu, kanye nendawo efanelekayo evamile ayikwazi ukutholwa. Kanye nezindleko zamahora okusebenza, izinto ezisizayo nazo ziphakeme.

Umthamo wokukhanyisa ukhawulelwe:Ukuphaza kwamakhalisa angena, ukusika kwe-plasma, ukusika kwamalangabi kanye ne-oxide emnyama, kunzima ukususa.
Imidwebo ebangelwa yizici zabantu zibaluleke kakhulu:Esezinhlelweni zokuphakamisa, ukuthutha kanye nokusebenza kwesakhiwo, ukuklwebheka okubangelwa ukungqongqoza, ukuhudula, isando kanye nezinye izinto zabantu ziba nzima kakhulu, futhi futhi kuyisizathu esikhulu sokwelashwa ngemuva kokwelashwa.
Izici zemishini: Kuphrofayili, ukugoba ipuleti, inqubo yokugoba, okubangelwa ukuklwebheka kanye nokuqala futhi isizathu esiyinhloko sokugqwala ngemuva kokwelashwa.
Ezinye izinto:-ngaliteliUkukhokhiswa kwensimbiEsikhathini sokuthengwa kwempahla, inqubo yokugcina, ngenxa yokuphakamisa, inqubo yokuhamba ye-bump kanye nemihubhe ingabi kakhulu, futhi ingenye yezimbangela zokugqwala.
