Kana iyo pombi yakashongedzwa, kurongeka kwave kure-pakati, hapana gaka rasara pakurongeka, groove haina kufoshorwa kune gobvu-yakavezwa pombi, uye hupamhi uye kureba kweweld hazvienderane neyakagadzirirwa.Mhedzisiro: Nekuti pombi haina pakati, iyo welding process ichave isingashande uye ichaita senge inyanzvi.Kana hupamhi uye kukwirira kwe weld kusingagutsi zvinotsanangurwa, hapana gaka pakati pevamwe, iyo gobvu-yakavezwa pombi haina foshoro groove, uye welding haigone kuzadzisa zvinodiwa zvesimba.
Zviyero: Groove mapaipi akasimba-akavezwa, siya mapaipi pamajoini, uye rongedza mapaipi kuti ave pamutsetse wepakati kana majoini atosungwa.Pamusoro pezvo, hupamhi hweweld seam uye kureba kunofanirwa kusungirirwa zvinoenderana nemirairo.
