Umahluko phakathi kombhobho wokunciphisa owolula oshushu kunye nombhobho wentsimbi we-LSAW unala manqaku mabini alandelayo:
I-1, ebangela ukungafani kumgangatho wemveliso ngenxa yeenkqubo ezahlukeneyo, ukunciphisa ukutshisa okutshisayo kwakhona kuqhutywe inkqubo emva kwenkqubo ye-welding ephezulu-frequency ukuba i-lsaw ipayipi yensimbi ayifumaneki -- I-Longitudinal ayikho umgca ocacileyo ngaphakathi nangaphandle kwe-burrs. Ubukho beBurr buya kuchaphazela i-tube fluid - flow, burr block flow yesiqhelo yolwelo, okukhokelela kwi-whirlpool. Ngokwemigaqo yobuchwephesha be-fluid, i-welding kufuneka ikhulise ukunyanzeliswa kwendawo, ukuyeka ukwenza ukhuseleko lombhobho kuncitshiswe kakhulu, i-hot stretch yokunciphisa inkqubo yokuvelisa intsimbi - ithathelwe ingqalelo ngokupheleleyo ubukho bomngcipheko we-burrs, ukunciphisa ukususwa kwe-burr, okwenza kube yinto efanayo. ubukhulu, akukho mahluko kwinkangeleko kwaye ingenamthungo. Ke ngokusuka kweli nqanaba lokujonga, ukunwebeka okushushu okucutha imibhobho okudityanisiweyo nako kugqibezele inguqu engenamthungo.

I-2, umgangatho we-Weld umisela ngokuthe ngqo umgangatho wombhobho odibeneyo, umbhobho ongenamthungo udityaniswe ngokwahlukana okukhulu kakhulu. I-Longitudinal emva kwe-welding high-frequency welding, i-seam seam set carbon ayikwazi ukupheliswa, i-weld kunye nomzali udibanise kunye kwaye ungaxutywanga ngokupheleleyo kwelinye - akakwazanga ukujamelana novavanyo lwexesha kunye noxinzelelo. I-Hot stretch yokunciphisa i-high-frequency welding welding pipe emva kokufudumeza ukuya kuyo yonke, iqondo lokushisa elipheleleyo le-annealing degrees 800, kwaye emva koko uvule inkqubo yokutshintsha, emva koko uthotho lweenkqubo, i-weld kunye nokusebenza kombutho womzali - kuye kwaba iyafana neyokunyibilika ngokupheleleyo, yenziwe kakuhle ukusuka kumthungo ukuya kwinguqu engenamthungo.
