welding titanium tubing

Kev tsim technology ntawmwelding titanium tubingnrog tsis tshua muaj zog thiab tsis tshua muaj alloy yog tus paub tab. Nyob rau hauv cov nqe lus ntawm kev kub siab tsis kam thiab cov qauv kev ntxhov siab tsis kam, tuab-walled titanium seamless kav feem ntau yog siv. Txawm li cas los xij, vim qhov tsis tshua muaj txiaj ntsig ntawm titanium seamless kav, lub voj voog ntev ntau lawm thiab lwm yam, kev tsim kho kom ruaj khov nws tau dhau los ua ib qho qauv hauv kev lag luam titanium yeeb nkab. Piv nrog titanium seamless yeeb nkab, titanium welded yeeb nkab muaj ntau thiab ntau pom tseeb kev zoo.

Tus qauv tsim ntawm titanium welded raj yog ASTM B338 / ASTM B862. Lub tsev nyias-phab ntsa vuam titanium tubing txais ib rab phom los yog ntau rab phom Tig / PAW tus kheej fusion vuam. Tom qab vuam, cov txheej txheem kev kho cua sov hauv online tau txais yuav. Los ntawm kev ua kom zoo dua cov txheej txheem welding thiab annealing, microstructures ntawm lub hauv paus hlau thiab weld tshav kub cuam tshuam cheeb tsam yog qhov zoo sib xws, thiab cov kev ntxhov siab vuam raug tshem tawm. Cov qauv welded yog ib yam, thiaj li yuav tau txais ASTM B862 titanium welded raj nrog zoo zoo.

Cov Kev Ntsuas Zoo

1. Kev ntsuam xyuas ntawm cov yeeb nkab vuam zoo yuav tsum tau ua los ntawm qhov kev sim flattening los yog kev ntsuas khoov. Cov qauv kuaj yuav tsum raug xaiv los ntawm txhua qhov ntau ntawm cov yeeb nkab tsim. Cov ntawv xeem ntawm cov khoom siv tib yam tuaj yeem txuas rau cov yeeb nkab thiab welded raws li qhov ntev ntawm cov yeeb nkab longitudinal seam.
1.1 Guided Bend Test-Rau Qib 1, 2, 2H, 7, 7H, 11,13, 14, 16, 16H, 17, 26H, thiab 33 ib tug longitudinal lossis transverse guided bend test ntawm lub vuam yuav tsum tau ua raws li qhov txoj kev tau teev tseg hauv ASME Boiler thiab Pressure Vessel Code, Seem VIII, Paragraph UNF-95. Lub ductility ntawm lub vuam yuav tsum suav tias yog qhov tsim nyog thaum tsis muaj pov thawj ntawm cov kab nrib pleb tom qab khoov hauv qhov vuam los yog nruab nrab ntawm cov vuam thiab lub raj hlau. Cov qauv kuaj yuav tsum tau xaiv los ntawm cov yeeb nkab uas tsim raws li qhov yuav tsum tau ua.
1.2 Rau Qib 3, 5, 9, 12, 15, 18, 19, 20, 21, 23, 24, 25, 34, 35, 37, thiab 38 qhov yuav tsum tau muaj rau cov kev xeem coj khoov
yuav tsum tau sib tham ntawm cov chaw tsim khoom thiab cov neeg yuav khoom.

2. Flattening Test-tig vuam titanium tubing nyob rau hauv qhov kawg mob yuav tsum muaj peev xwm tiv taus, tsis muaj cracking, flattening
nyob rau hauv ib tug load thov maj mam nyob rau hauv chav tsev kub kom txog rau thaum qhov kev ncua deb ntawm lub load platens yog H ntiv tes. Lub vuam yuav tsum tau muab tso rau ntawm 90 degree lossis 270 degree mus rau kev taw qhia ntawm cov ntaub ntawv thov. H yog xam raws li nram no:

H=Yam tsawg kawg nkaus flattened qhov siab, hauv. (mm),
t=nominal phab ntsa thickness, in. (mm) thiab,
D=nominal yeeb nkab txoj kab uas hla, in. (mm) (tsis yog yeeb nkab loj), thiab
Rau Qib 1, 2, 2H, 3, 7, 7H, 11, 13, 14, 16, 16H, thiab 26H.
e=0.04 txog 1 nyob rau hauv. yeeb nkab loj, thiab
e=0.06 tshaj 1 in. yeeb nkab loj.
Rau cov qib uas tsis tau qhia saum toj no, qhov yuav tsum tau ua rau qhov kev xeem flattening yuav tsum tau sib tham ntawm cov chaw tsim khoom thiab cov neeg yuav khoom.
2.1 Tag nrho cov kev suav raug muab sib npaug rau ob qhov zauv. Kev tshuaj xyuas kom tawg yuav tsum yog los ntawm qhov muag tsis pom.
2.2 Thaum tsis tshua muaj D-rau-t piv cov khoom siv tubular raug kuaj, vim tias cov kab mob raug yuam vim geometry yog qhov tsis tsim nyog.
siab nyob rau sab hauv ntawm qhov chaw rau rau thiab kaum ob teev, cov kab nrib pleb ntawm cov chaw no yuav tsum tsis txhob ua rau
kev tsis lees paub yog qhov piv txwv D-rau-t tsawg dua kaum (10).
