X42 SSAW Umbhobho Spiral Welded Tube
Yazisa:
Kwintsimi yeemibhobho zetsimbi, iindlela ezahlukeneyo ze-welding zisetyenziselwa ukufikelela kwizinga eliphezulu kunye nokudibanisa okuthembekileyo. Enye indlela enjaloukuwelda kwe-arc entywilayo(SAW), edlala indima ebalulekileyo ekuvelisweni kombhobho we-X42 SSAW. Njengenkokeli yoshishino, iCangzhou Spiral Steel Pipe Group Co., Ltd., eyaziwa ngokuba yiWuzhou brand, ithobela imigangatho yamazwe ngamazwe kwaye iqinisekisa ukuba iimveliso zayo (kuquka i-X42 spiral submerged arc welded pipe) idibana ne-API Spec 5L, ASTM A139, ASTM A252 kunye ne-EN 10219 ye-S219. iqaqambisa iingenelo zokusebenzisa ukuwelda kwe-arc entywilayo kwi-spiral kwimveliso yombhobho odityanisiweyo.
Funda malunga neSpiral Submerged Arc Welding (SAW):
I-Spiral submerged arc welding, ekwaziwa ngokuba yi-SAW, bubuchule obukhethekileyo bokuwelda obusetyenziselwa ukwenza imibhobho edityanisiweyo efana ne-spiral welding.X42 SSAW umbhobho. Ubuchwephesha bubandakanya ukunyibilikisa i-wire flux kunye nesiseko sesinyithi usebenzisa ubushushu obuveliswa kukutsha kwe-arc phakathi kocingo kunye ne-flux phantsi kwe-flux layer. Uluhlu lwe-flux lusebenza njengesithintelo sokukhusela, ukuthintela ukungcola kwe-atmospheric ukuphazamisa inkqubo ye-soldering. Le ndlela ineenzuzo ezininzi kunezinye iindlela zokuwelda.

Uvavanyo lweHydrostatic
Izinto eziluncedo kwi-spiral submerged arc welding:
1. Iiwelds ezihambelanayo kunye neziphezulu: Indlela ye-SAW esetyenziswe kwipayipi ye-X42 ye-SSAW ivelisa i-welds efanayo kunye nekhwalithi ephezulu. Xa i-arc ifakwe kwi-flux, idala indawo elawulwayo ekhusela indawo ye-solder ukusuka kwizinto zangaphandle, ukuqinisekisa ukuhambelana okuhambelanayo kunye nokuthembeka. Oku kubangela ukuveliswa kwemibhobho e-spiral welding enamandla akhethekileyo kunye nokuqina.

2. Ukonyuka kokusebenza kakuhle: I-Spiral submerged arc welding inika impumelelo ebonakalayo ngenxa yobume bayo obuzenzekelayo. Inkqubo ibandakanya ukuqhubeka, ukondla ngokuzenzekelayo kwi-welding wire, okubangela ukuveliswa ngokukhawuleza ngelixa ugcina ukuchaneka.
