Ukuguqulwa kwengxenye
1. Ingxenye ikhubazekile ngesikhathi sokuthutha, okuholela ekugobeni okufile noma okumnene, okwenza ingxenye ingakwazi ukufakwa.
Ukuhlaziya imbangela:
a) Ukuguqulwa okukhiqizwa lapho izingxenye zenziwa, ngokuvamile kuvezwa njengokugoba okunensayo.
b) Lapho ingxenye izothuthwa, indawo yokusekela ayifaneleki, njengokuthi ukhuni lomcamelo ongenhla nangaphansi aluqondile, noma indawo yokupakisha ingaphansi, ukuze ilungu libe nokugoba okufile noma ukuwohloka kancane.
c) Izingxenye zikhubazekile ngenxa yokushayisana ngesikhathi sokuthutha, ngokuvamile kubonisa ukugoba okufile.
Izinyathelo zokuvimbela:
a) Ngesikhathi sokwenziwa kwezingxenye, izinyathelo zokunciphisa ukuguquguquka kuyothathwa.
b) Emhlanganweni, kufanele kuthathwe izinyathelo ezinjengokuguqulwa kwe-reverse.Ukulandelana komhlangano kufanele kulandele ukulandelana, futhi izisekelo ezanele kufanele zisethwe ukuze kuvinjelwe ukuwohloka.
c) Enqubweni yezokuthutha nezokuthutha, naka ukumiswa okunengqondo kwamaphedi.
Izixazululo:
a) Ukugoba okufile kwelungu kuvamise ukuphathwa ngokulungiswa komshini.Sebenzisa ojeke noma amanye amathuluzi ukulungisa noma ngelangabi le-oxygen acetylene ngemuva kokulungiswa kokubhaka.
b) Lapho isakhiwo sigoba ngobumnene ukuguquguquka, thatha ukulungiswa kokushisa komlilo we-oxyacetylene.
2. Ngemva kokuhlanganisa amalungu ensimbi yensimbi, ukuhlanekezela okugcwele ubude kudlula inani elivumelekile, okuholela ekufakweni okungalungile kwekhwalithi yensimbi.
Ukuhlaziya imbangela:
a) Inqubo yokuthunga ayinangqondo.
b) Usayizi wamanodi ahlanganisiwe awuhlangabezani nezidingo zokuklama.
Izixazululo:
a) Izingxenye zomhlangano zokumisa itafula lomhlangano, njengokushisela phansi kwelunga elilinganayo, ukuvimbela ukuqubuka kwempi.Ukuhlangana kwetafula kufanele kube yizinga ngalinye le-fulcrum, ukushisela ukuvimbela ukubola.Ikakhulukazi umhlangano we-boam noma isitebhisi, kuyadingeka ukulungisa ukuguqulwa ngemuva kokubeka i-welding, futhi unake ubukhulu be-node ukuze uhambisane nomklamo, ngaphandle kwalokho kulula ukubangela ukuhlanekezela kwengxenye.
b) Ilungu elingaqinile kahle kufanele liqiniswe ngaphambi kokuphenduka nokushisela, futhi ilungu kufanele lilinganiswe ngemuva kokuphenduka, ngaphandle kwalokho ilungu alikwazi ukulungiswa ngemva kokushisela.
3. I-arch yezingxenye, inani lokomile okukhulu noma ngaphansi kwevelu yokuklama.Uma inani le-arch lengxenye lincane, ugongolo lugoba ngemva kokufakwa;Uma inani le-arch likhulu, ukuphakama kwendawo ye-extrusion kulula ukudlula izinga.
Ukuhlaziya imbangela:
a) Usayizi wengxenye awuhlangabezani nezidingo zokuklama.
b) Enqubweni yokumiswa, amanani alinganiselwe nabaliwe awasetshenziswa
