I-Spiral Pipe (i-saw steel pipe): nge-strip ngomatshini wokwenza umqulu, i-spiral direction ejikelezayo, emva koko i-arc ifakwe emacaleni aphindwe kabini yenziwa nge-capacitor.Inkqubo yokuvelisa umbhobho wentsimbi odityanisiweyo, othanda ukuvuza kwiimeko ezininzi, njengokuwelda kunye necala elingalunganga.Nangona kunjalo, kwezi meko kubonakala i-Chlamydia yeyona nto inzima kakhulu ukukwazi ukudibanisa i-spiral steel butt weld.

Okubizwa ngokuba yi-trachoma: ukuba inkqubo ye-welding kwindawo yangaphakathi ye-weld okanye i-welds, akuzange kubekho ukungena ngokucokisekileyo kwamasuntswana okanye ama-bubbles, kunye nokumila komgodi wesanti ebusweni be-weld.Izizathu zetrakoma zezi zilandelayo:
I-1, ukunikezelwa kwetotshi ye-welding ngexesha langoku kuncinci kakhulu, i-capacitor ifutshane kakhulu, i-capacitor ayizange igqitywe ngokupheleleyo xa i-welding surface ye-welding iye yaqina, ngoko kwenzeka ukungena kwesanti okanye kungekhona amaqamza.
2, i-scimitar tune kwigophe elimile okwexesha kungekho mpundu ilungileyo, umcu wempundu awuhambelani ncam, bekukho umsantsa omninzi kakhulu phakathi komcu wempundu.
I-3, intsimbi edityanisiweyo yentsimbi xa macala omabini engakhange acoceke umphetho womhlwa okanye isikali.
I-4, akukho kugcinwa ngexesha elifanelekileyo kwezixhobo zokuvelisa ukucoca.Uthuli lwe-workbench okanye ukungcola, luwela ngempazamo kwi-gap kwi-butt welding yentsimbi.
I-5, ukushisa okusebenzayo kuphantsi kakhulu okanye kumanzi kakhulu iworkshop, echaphazela ukushisa kunye nokoma kwamanqaku e-welding.
