Umbhobho wentsimbi ye-Spiral tulawulo lobushushu

Ubushushu bentsimbi yombhobho weSpiral buchatshazelwa ikakhulu yi-high-frequency eddy thermal power, i-high-frequency eddy yangoku amandla okufudumeza achaphazeleka ikakhulu ngamaza, amandla kunye ne-thermal eddy yangoku yokuvuselela amandla alinganayo kwisikwere;kodwa nangamandla ombane wokuvuselela amandla akhoyo ngoku, akhoyo kunye ne-capacitance, inductance.

Xa ukungabikho kwegalelo lokushisa, i-weld edge ifudumala ukuya kwiqondo lokushisa elingaphantsi kwe-welding, isakhiwo sesinyithi sihlala siqinile, ukubunjwa kokudibanisa okungaphelelanga okanye ukungena;akwanelanga xa igalelo ubushushu, weld edge phezu ubushushu soldering eshushu, okubangela utshise okanye droplet, ukuze weld ukwakheka Imiqolomba.

Ukuwelda i-multilayer yombhobho wentsimbi we-spiral welded ikwaqwalasela ubushushu obuphakathi komgangatho ukulawula izinga lokupholisa kufutshane nendawo ye-weld.Ubushushu be-interface kunye nobushushu be-preheat bufana ngokubanzi.Ngaphantsi kokuphepha ukutshisa kakhulu kwindawo ekufutshane nendawo yomthungo phakathi komgangatho ophezulu kuthintela ubushushu obubandayo bokuqhekeka ngexesha le-welding ye-multi-pass.Emva kokunyangwa kobushushu kunye nokwakhiwa kombhobho wobushushu aqhele ukwenziwa emva konyango lobushushu emva kwe-welding kunye nonyango lobushushu.Kodwa ukwakhiwa kummandla we-alpine, xa i-inter-preheat kunye ne-interface yokulawula ukushisa kunzima ukudlala indima enkulu, kuyimfuneko ukuthatha amajoyina athile emva kokushisa kwe-welding kunye namanyathelo okunyanga ukushisa.

Inkqubo yokufakela umbhobho wentsimbi

umbhobho Spiral ukusebenza kwisiza, okokuqala ngokwezixhobo kunye nokufakwa isikhundla umbhobho yokukhupha, kwaye ebaleni iya kuba ubude ethile umbhobho ngamnye womlinganiselo ulungile, uphawu ubungakanani obuthile kunye nendawo ulungiselelo ukwenzela ukuba kube lula ukugwetywa kojongano, phantsi ukusetyenziswa kwetyhubhu ye-crane, ityhubhu ephantsi ngexesha lokunyusa isilingi senayiloni ukukhusela ukugquma kombhobho.

1:lungisa umlomo

Ukulungisa amazibuko agxininiswe ekuqhubeni umbhobho womzi-mveliso kugqityiwe, ukwenzela ukuba kuqinisekiswe umgangatho wokuwelda, ngaphambi kokuba ukuwelda kwenziwe uhlolo olubanzi, ukulungiswa, ukwenza isiphelo sombhobho, i-angle ye-bevel, i-edge blunt, ukujikeleza, njl., kuhambelana nabalingane babo. kwiimfuno ubungakanani joint, imfuno umbhobho ngamnye kwenziwa kwintsimi beveling inkqubo, ukusetyenziswa kwerhasi welding ukusika, ukususa slag uze usebenzise ivili olukhazimlisiweyo agudileyo.

Iinkqubo zokusebenza ezihambelanayo: Jonga ubungakanani bomnxibelelanisi wojongano→ibhrentshi ecacileyo→misela kwaye ulungelelanise indawo yombhobho wentsimbi welds longitudinal wagxadazela→I-conduit yokuqala ejonge amaqabane alungeleleneyo alungelelanise i-gap dimension→iintambo zentambo zombhobho zilinganisa zijonge ngqo→ukuwelda indawo

2: ukuwelda

I-interface welding usebenzisa i-arc welding, kwakhona ukuxhasa, yasinda amaxesha amabini, kwaye ixesha ngalinye i-welding seam igqityiwe, indawo nganye ye-arc ye-welding ikhokelela ukuba igxininiswe.Ukulungisa imibhobho yokudibanisa i-welding kufuneka ilandelwe ngomlomo, i-slag, i-engile ye-engile ye-bevel ekupheleni ukuya ekupheleni kobuso, i-edge e-blunt, i-gap kufuneka ihambelane nenkcazo;ikliphu ayinakunceda ukuwelda okanye ukufudumeza abalingane umsantsa ocutha umsantsa welding.Izixhobo ezihambelanayo kufuneka zigungxulwe kunye nodonga lwangaphakathi, kunye nerula ende eyi-300mm ukuze ijikeleze udonga lwangaphakathi lujikeleze ujongano, isibuko esingalunganga sivumela ukukhangela okungaphelelanga kufuneka kube ngu-0.2 umphinda-phinde umehluko phakathi kobukhulu bodonga, kwaye ungabi mkhulu kuno-2mm.
