Umbhobho wentsimbi owenziwe ngesinyithi unokudityaniswa usebenzisa i-arc yemveli yombane.Akukho mmahluko omkhulu kwiipropati ze-mechanical welding kwi-galvanized and non-galvanized steel pipes ukuba i-welding yenziwe ngokufanelekileyo.
Imibhobho yegalvanized idla ngokudityaniswa okanye ukuxhathisa usebenzisa i-electrode ekhethekileyo enciphisa ukuncamathela kwindawo yokusebenza.Okokuqala, imathiriyeli ye-welding echanekileyo yeyona nto iphambili yokufumana umdibaniso ongenasiphako kunye nokusebenza kakuhle koomatshini.I-J421, i-J422, i-J423 yeyona nto ifanelekileyo yezandla phantsi kwintsimbi yentsimbi.Okwesibini, susa iingubo zeZn ngaphambi kokuba uqale ukuwelda.Gcoba i-coating kwindawo ye-weld kunye ne-1/2-intshi ye-zinc yokugqoka, kwaye iyanyibilika kwaye ifakwe kwindawo yomhlaba.Imanzise loo ndawo ngesitshizi-kwi-oyile egqobhozayo.Ukusebenzisa i-grinder entsha, ecocekileyo ukususa i-galvanized layer.
Emva kokugqiba ukulungiswa kwamanyathelo okukhusela kunye ne-anti-corrosion, unokwenza i-welding.Ukuwelda lubushushu obuphezulu kwaye umbhobho wokuwelda ukhupha umsi oyingozi oluhlaza.Qaphela, lo msi unetyhefu ngokwenene emntwini!Ukuba uyaphefumla, oku kuya kukunika intloko ebuhlungu, ityhefe imiphunga yakho nengqondo.Ke umntu kufuneka asebenzise isiphefumlo kunye ne-exhausts ngexesha lokuwelda kwaye uqiniseke ukuba unomoya ogqwesileyo kwaye uqwalasele imaski yamasuntswana.
Emva kokuba iingubo ze-zinc kwindawo ye-welding yonakaliswe.Ukupeyinta indawo yokuwelda ngepeyinti etyebileyo yezinc.Ekusetyenzisweni kokusebenza, umbhobho wensimbi owenziweyo kunye nobubanzi obungaphantsi okanye obulingana ne-100mm uya kudibaniswa ngentambo, kunye nomgca owonakalisiweyo we-galvanized kunye nenxalenye yentambo evezwayo ngexesha lokuxhamla kuya kuba unyango lwe-antiseptic.Umbhobho wentsimbi owenziwe ngesinyithi onobubanzi obungaphezulu kwe-100mm uya kudityaniswa ngeeflange okanye izifakelo zemibhobho evalekileyo, kwaye inxalenye yokuwelda yombhobho kunye neflange iya kuphinda ifakwe igalvan.
