Vuam stainless hlau qhov rooj thiab qhov rais yog zoo li kev phais ntawm ib tug precision ntsuas - nws yuav tsum tau ob leeg lub zog thiab ib tug du nto. Cov khoom no muaj cov ntsiab lus melting 20% siab dua li cov hlau zoo tib yam thiab cov coefficient loj ntawm thermal expansion, ua rau nws yooj yim rau deformation thaum vuam. Yog li ntawd, kev tswj qhov kub thiab txias thiab qhov cua sov- thaj tsam cuam tshuam (HAZ) yog cov cim tseem ceeb thaum xaiv lub tshuab vuam. Piv txwv li, thaum cov hlau zoo tib yam tsuas yog yuav tsum tau vuam kub ntawm 1500 degree, stainless hlau xav tau nyob ib ncig ntawm 1650 degree. Ib txhij, qhov kub hauv 3 hli ntawm qhov vuam yuav tsum tsis pub tshaj 300 degree; txwv tsis pub, qhov nto passivation zaj duab xis yuav puas, ua rau xeb.
Mainstream Vuam Tshuab Kev sib piv
- Argon Arc Vuam Tshuab: "Golden Partner" rau Stainless Hlau Qhov Rooj thiab Qhov rai. Nrog kev tiv thaiv roj argon, HAZ tuaj yeem tswj tau nyob rau hauv 2 hli, ua rau muaj nyiaj dawb - weld dawb. Qhov tsis zoo yog tias nws yuav tsum muaj qee yam kev txawj ntse; beginners yog nquag welding los ntawm los yog tawm hauv porosity.
- Laser Vuam Tshuab: "Black Technology" rau siab -Qhov Rooj thiab qhov rais. Vuam ceev yog 3 zaug sai dua argon arc vuam, nrog HAZ tsuas yog 0.5 hli thiab yuav luag tsis muaj deformation. Txawm li cas los xij, cov khoom siv tus nqi yog 5-8 npaug ntawm TIG vuam, ua rau nws tsim nyog rau cov tuam txhab koom nrog ntau lawm.
- Kev tuav arc vuam: A "jack- ntawm-tag nrho- kev lag luam" rau kev kho thaum muaj xwm ceev. Cov khoom siv yog pheej yig, tab sis nws tsim ntau spatter, thiab cov weld yog nquag blackening, yuav tsum tau sib tsoo tom qab. Nws yog qhov tsim nyog rau kev ua haujlwm sab nraum zoov ib ntus.
Peb lub hauv paus ntsiab lus rau kev xaiv tshuab:
- Xav txog thickness: Xaiv TIG vuam rau 0.8-2mm nyias daim hlau; xav txog laser vuam rau daim hlau tuab dua 2 hli.
- Xav txog batch loj: Xaiv TIG vuam rau txhua hnub ntau lawm hauv qab 50 daim; pom zoo laser vuam rau ntau tshaj 100 daim.
- Xav txog kev siv nyiaj: Xaiv 2000-5000 yuan TIG vuam tshuab rau tsev neeg kev cob qhia; rau cov chaw tsim khoom, lub tshuab laser vuam tshuab peev ntawm 30,000-80,000 yuan raug pom zoo.
