Ukuwelda kweimibhobho yobheduibisoloko iyinxalenye eyimfuneko kwimveliso kunye nokusetyenziswa kweetyhubhu zobhedu.Ngexesha lotyando olulolo hlobo, iingxaki ezincinci ezahlukeneyo zihlala zisenzeka.Siyidibanisa njani ityhubhu yobhedu, inyathelo elilula liboniswa apha namhlanje.
(1) Ukulungiselela kwangaphambili
Ngaphambi kwe-welding, kuyimfuneko ukuba ube nokuqonda okuthile kwezixhobo ze-welding, izixhobo ze-welding, kunye neemfuno zemveliso.Kuyimfuneko ukujonga ukuba i-gas ehambelanayo kwi-cylinder ye-oksijeni kunye ne-second-block block gas cylinder yanele, ukuhlolwa kwangaphambili kwecandelo ngalinye kuhambelana, kwaye ubuso bezinto eziphathekayo bucocekile, njl. amalungiselelo
(2) Ukuwelda
Xa u-welding, kuyimfuneko ukutshisa ityhubhu yobhedu, ukufudumeza indawo apho ityhubhu yethusi kufuneka idityaniswe nomlilo, kwaye ugcine umbala.Ngokuqhelekileyo, ubomvu obumnyama bumalunga nama-600 ngokukaCelsius, umbala obomvu onzulu umalunga nama-700 ngokukaCelsius, kwaye i-orenji imalunga ne-1000 ngokukaCelsius.
Ngethuba lenkqubo ye-welding, iindawo ezonakalisiweyo zikhuselwe.Ngokuqhelekileyo, ivalve ye-solenoid, i-valve yeendlela ezine, njl.I-welding flame ayikwazi ukusetyenziswa njenge-electrode yokufudumala.Ngethuba lenkqubo ye-welding, i-welding kufuneka igqitywe ngokukhawuleza nangokuchanekileyo, ngokukhethekileyo ngexesha elinye.Xa i-welding sele iza kuphelisa ukukhutshwa, ubushushu bulawulwa malunga nama-300 degrees
(3) Emva kwe-welding
Emva kokuba i-welding igqityiwe, kufuneka ipholiswe ixesha elithile, kwaye i-oxide, uthuli kunye ne-slag ye-welding kwi-tube yobhedu kufuneka icocwe nge-nitrogen eyomileyo, kwaye ezinye iindawo ezilahlekileyo ze-welding kufuneka zilungiswe.Ngaphambi kokulungisa i-welding, i-oxide layer phezu komhlaba kufuneka isuswe.Emva kokulungiswa kwe-welding, inxalenye ye-oxidized isafuna ukuphathwa, kwaye emva kokugqitywa, iphinda iphathwe ngokuvuthela komoya ukugcina udonga lwangaphakathi lwetyhubhu yobhedu yomile kunye nodonga lwangaphandle luqinile.
