Vuam Txheej Txheem Yuav Tsum Tau Muaj rau 316L Stainless Hlau Yeeb

1.Welding Method

Raws li cov yeeb yam ntawm stainless hlau, raws li deb li sai tau kom txo tau tus nqi ntawm cov tswv yim tshav kub, yog li kev siv ntawm phau ntawv arc vuam, argon arc welding ob txoj kev. d> φ159mm adopts argon arc vuam mus rau hauv qab, kev siv caj dab arc vuam npog nto thiab d <φ159mm argon="" arc=""> Vuam tshuab txais yuav kev tuav kev ua lag luam arc / Argon arc vuam Dual-purpose WS7-400 inverter rau kev lag luam.

2.Qhov Khoom Siv

Austenitic stainless hlau yog ib lub cav tshwj xeeb, kom ua tau raws li sib koom tes muaj qhov kev ua haujlwm zoo tib yam, yuav tsum ua raws li "qhov sib npaug ntawm cov qauv" los xaiv vuam cov khoom. Nyob rau tib lub sijhawm, txhawm rau txhim khu kev sib koom ua haujlwm rau thermal cracking thiab intergranular corrosion muaj peev xwm, thiaj li hais tias tsawg tus ferrite cov pob qij, xaiv HooCr19Ni12Mo2 Argon arc welding hlau. Taug kev arc vuam electrode CHS022 li cov ntaub ntawv muab tub lim.

3.Qhov Parameters

Austenitic stainless hlau yog ib qho tseem ceeb ntawm lub thermal rhiab heev, yog li siv cov me me tam sim no, ceev vuam, ntau txheej vuam kom nruj tswj tau qhov kub ntawm cov khaubncaws sab nraud povtseg, kom qhov kub ntawm cov txheej yog tsawg dua 60 ℃.

4.Txhua daim ntawv thiab kev sibtham qhov rooj Vuam

Groove nyob rau hauv daim ntawv ntawm V-puab groove. Vim yog siv lub voj me me tam sim no, sib sib zog nqus mus tob, ces qhov tawg qhov ntug ntawm qhov zawj yog me dua cov pa roj, li 0-0.5 hli, lub kaum sab xis loj dua cov pa roj, txog 65-70 degrees. Vim tias lub thermal expansion coefficient ntawm cov hlau tsis muaj xim tsis muaj zog, vuam kev nyuab siab dua. Yuav tsum tau muab txoj hlua txhuam nrawm. Rau cov voj voom ntawm dligmmmmm siv ob qho chaw taw qhia. d = φ89- φ219mm siv qhov siv peb qhov taw qhia. D≥φ219mm txais plaub-pointing positioning los nrhiav qhov ntev ntawm 6-8mm.

5.Txhua Cov Kev Xav Tau

⑴ Kev Tiv Thaiv Ntawm Cov Kws Ua Lag Luam Kws Ntaus Ntsuas Carts Txuas Txuas Disease DC, thiab Argon Arc Vuam Txuas Txuas Txuas Mus Txuas Nkag Tiag

⑵ welding hlau nrog stainless hlau hlau txhuam tawm ntawm cov tawv nqaij oxidized, thiab nrog acetone ntxuav. Lub electrode yuav tsum tau qhuav ntawm qhov kub ntawm 200-250 degrees rau 1 xuab moos. Txhua lub lag luam muaj nyob nrog cov thooj phom insulated, thiab cov ci electrodes yuav tsum muab rau hauv cov thawv kub-insulated, nrog rau kev siv.

⑶ welding ua ntej qhov workpiece zaws ntawm ob tog ntawm 25 hli ntawm cov roj thiab lwm yam kev ntxuav, thiab nrog acetone ntxuav ob sab ntawm txoj kab nqes ntawm qhov hli 25.

⑷ Argon arc vuam steel hlau, lub nraub qaum yuav tsum tau muaj cov tshuaj tiv thaiv argon, yuav kom rov qab tuaj molding. Kev khiav ntawm argon nyob rau hauv qhov pipeline yog 5-14l / min thiab qhov zoo npaum li cas argon ndlwg yog 12-13l / min.

⑸ welding, weld thickness yuav tsum yog li nyias li sai tau, thiab hauv paus fused zoo. Thaum lub arc yog nyob rau hauv daim ntawv ntawm ib txoj kev nqes. Yog hais tias muaj ib qho kev nruj ntsws, lub pob zeb yuav tsum tau hnav tawm. Arc quenching yuav tsum tau ua nyob hauv qhov zawj, thiab cov kaus poom dej yuav tsum tau ntim kom tiv thaiv cov kab nrib.

⑹ vim hais tias cov hlau tsis muaj steel hlau austenitic stainless hlau, yuav kom tiv thaiv cov carbonization ntawm cov nag lossis daus interrupts thiab intergranular corrosion, yuav tsum nruj me ntsis tswj lub interlayer kub thiab txias txias tom qab welding. Yuav tsum tau tswj qhov ntsuas kub ntawm cov txheej hauv qab 60 ℃, tom qab vuam tas yuav tsum tau dej tam dej txias tam sim ntawd, tib lub sijhawm siv qhov vuam vias. Qhov no symmetrical thiab dispersed welding ib theem zuj zus tsis tsuas yog nce lub ceev ceev ntawm kev sib koom tes, tab sis kuj txo cov vuam kev vuam.

6.Results

⑴ kuaj pom tsis muaj pores, khaus hlav, qias neeg, thiab tom hniav lwv, ua zoo.

Cov hnoos qeev yog ncab. Bending xyaum ua tej yam, tag nrho cov khoom siv dag zog yog ua tau raws li txoj cai tsis nrhiav kev ua hauj lwm ntawm fusion thiab keej.

⑶ Macroscopic metallographic kev soj ntsuam, pom hais tias qhov txuas fused zoo. Melted tsaug 1-1.5mm. Kev tshuaj ntsuam me me, nws cov khoom siv ntawm niam txiv thiab cov cua kub cua yog cov koom haum, cov hlau txhuam cov hlau yog cov khoom siv fossite (4%). Nws ua tiav txaus cov kev cai ntawm intergranular corrosion thiab brittleness, thiab xyuas kom zoo ntawm welding engineering.
