Lapho ushisela amapuleti ensimbi awugqinsi ngaphezu kuka-9mm ngaphansi kwezinga lokushisa elibi, kufanele kusetshenziswe ukushisela okunezingqimba ezimbili.I-welding ifuthwa kusukela phansi kuya phezulu, futhi i-welding ngayinye ishiselwa kanye, njenge-welding infix, ngaphambi kokushisela futhi.Akuvunyelwe ukuqala i-arc ezintweni zokuqala zokushisela.Uma isakhiwo sensimbi sifakwe endaweni, uma likhithika noma umoya ungaphezu kuka-6m/s, misa ishede elivikelayo.

Kodwa i-welding evaliwe iqeda ngokuphelele i-rewelding, futhi i-welding iyamiswa ngokuvumelana nendinganiso yenqubo ye-welding yesakhiwo sensimbi ngaphansi kokushisa okungalungile.Lapho izinga lokushisa lokusebenza lingaphansi kuka-0 ℃, ukuhlolwa kwenqubo yokumboza kwenziwa enamathela ezintweni ezilwa nokugqwala.Ukugqwala, amabala kawoyela, ama-burrs nezinye izinto ezisebusweni bengxenye kumele kuhlanzwe ngesikhathi sokumbozwa, futhi indawo engaphezulu kufanele ibe buthuntu futhi yisicefe.Ungayeki umsebenzi wokudweba uma kuneqhwa noma kuneqhwa elincanyana ezingxenyeni.

Lapho uthutha futhi ufaka izakhiwo zensimbi ebusika, izinyathelo zokulwa ne-skid eziphansi ziyamukelwa.Izingxenye ziyapakishwa futhi zilinganiswe.Indawo iqinile futhi ayinawo amachibi, futhi akukho qhwa esibhakabhakeni.Lapho izingxenye zohlobo olufanayo kanye nokucaciswa kupakishwa, izingxenye kufanele zigcinwe zisezingeni futhi amaphedi kufanele abekwe emgqeni ofanayo oqondile ukuze kuvinjelwe izingxenye ukuthi zingasheleli.Ngokwezidingo zezinga lokushisa elibi ngaphambi kokufakwa kwesakhiwo sensimbi, ikhwalithi yesakhiwo sensimbi izophinde ihlolwe, futhi izingxenye eziye zakhubazeka ngesikhathi sokukhiqiza kanye nokuthuthwa nokuqoqwa kuzolungiswa futhi kulungiswe phakathi. -moya.

Uma usebenzisa izintambo zensimbi ukuze uphakamise izingxenye zensimbi, kuyadingeka ukwengeza ama-anti-skid spacers phansi, futhi amapuleti okuxhuma aphakanyiswe nezingxenye ngasikhathi sinye, kanye nezinto ezisetshenziswa ngabasebenzi bokufaka ziboshwe ngokuqinile nazo. izingidi zezintambo.Ngokuvumelana neshadi ledatha elivamile lokufakwa kwengxenye yensimbi okungeyona eyezisebenzi okujwayelekile kwezinga lokushisa, ukufakwa kuzomiswa ngokuqinile ngokuvumelana nethiyori evamile evamile phakathi nokwakhiwa kwephrojekthi.Inqubo yokushisela yedivayisi yesakhiwo sensimbi eyenziwe ngokwezifiso, izinhlangothi ezimbili zengxenye azikwazi ukuyeka ukuthungatha ngesikhathi esifanayo.
