Umahluko ophambili phakathi kwemibhobho emibini edityanisiweyo yombhobho we-spiral welding kunye nombhobho odityanisiweyo othe ngqo ngumahluko kwifomu ye-welding.

Umbhobho odityanisiweyo we-Spiral yintsimbi ephantsi yekhabhoni yekhabhoni okanye ingxubevange ephantsi yolwakhiwo lwentsimbi eqengqeleke kwityhubhu engenanto ene-engile ethile ye-helix (ekwabizwa ngokuba yi-engile yokubumba), kwaye emva koko idityaniswe kwaye yenziwe ibe yindibaniselwano yombhobho, enokusebenzisa umcu omxinwa. intsimbi Ukuveliswa kwemibhobho yentsimbi edayamitha enkulu.Umbhobho odityanisiweyo we-Spiral ubukhulu becala yi-spiral submerged arc welded pipe (SSAW), esetyenziswa rhoqo kulwakhiwo lwemibhobho yegesi eyahlukeneyo eTshayina.Inkcazo yayo ibonakaliswe "ngobubanzi bangaphandle * ubukhulu bodonga".Imibhobho edityanisiweyo ene-Spiral idityaniswe kwicala elinye kwaye idityaniswe macala omabini.Umbhobho odibeneyo uya kuqinisekisa ukuba uvavanyo lwe-hydraulic kunye nokuqina kwamandla kunye nokusebenza okubandayo okugoba kwe-weld kuhambelana nemimiselo.

Umbhobho odityanisiweyo othe tye yi-high-frequency current kunye ne-proximity effect inyathelo eliza kuveliswa ngumaleko we-solder phambi kokuba i-welding yenziwe ngumatshini wokubumba, kwaye umda wetyhubhu engenanto ishushu kwaye iyanyibilika, kwaye ixutywe. phantsi koxinzelelo oluthile, ukubumba okupholisa.Umbhobho odityanisiweyo we-high-frequency straight one-weld welding usetyenziswa apho ungqameko lombhobho ongenanto unyibilikiswa yi-high-frequency current (ERW), ebizwa ngokuba yi-straight seam entywiliselwe i-arc welded pipe (LSAW) ngokunyibilika nge-arc yombane.

Amandla ombhobho we-spiral welded ngokubanzi uphezulu kunombhobho odityanisiweyo othe tye.Eyona nkqubo yokuvelisa i-arc welding ephantsi kwamanzi.Umbhobho odityanisiweyo we-spiral unokuvelisa imibhobho edityanisiweyo enedayamitha zemibhobho eyohlukeneyo enobubanzi obungenanto, kwaye inokuvelisa imibhobho edityanisiweyo enedayamitha ezinkulu enezikhewu ezimxinwa.

Inkqubo yokuvelisa umbhobho odityanisiweyo othe tye ilula ngokwentelekiso, ikakhulu kwinkqubo yemveliso, eyahlulahlulwe yaba yi-high-frequency welded straight seam welded pipe kunye ne-arc entywiliselweyo idityaniswe ngqo nombhobho odityanisiweyo.Umbhobho we-welded seam ochanekileyo unomsebenzi ophezulu wokuvelisa, ixabiso eliphantsi kunye nophuhliso olukhawulezayo.

Nangona kunjalo, xa kuthelekiswa nombhobho odibeneyo odibeneyo wobude obufanayo, ubude be-weld bunyuswe ngama-30 ukuya kwi-100, kwaye isantya sokuvelisa siphantsi.Ke ngoko, imibhobho edityanisiweyo encinci idityaniswe ubukhulu becala ingumthungo othe tye, ngelixa ubukhulu becala imibhobho edityanisiweyo idityanisiwe.
