Dab tsi yog Astm cov qauv?

ASTM International (yav tas los Asmeskas Koom Haum rau Kev Sim thiab cov ntaub ntawv (luam tawm ntau 12,000 tus qauv kev txhawb nqa cov qauv kev txhim kho cov ntaub ntawv, cov khoom lag luam, thiab cov kev pabcuam, thiab kev pabcuam. Rau cov tuam ntxhab zoo li Huayang Steel Yeeb Nkab Co., Ltd.-tus tsim khoom lag luamCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav{-} Astm cov qauv tsis yog kev ua raws cai tab sis lub hauv paus ntawm cov khoom lag luam zoo, thiab kev ntseeg lag luam, thiab cov neeg siv khoom ntseeg. Cov qauv qauv txhais tau qhov tseem ceeb rauCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav, los ntawm cov tshuaj muaj kuab lom thiab cov kws kho mob rau kev tsim cov txheej txheem, ua kom pom kev sib xws thoob plaws cov kab ke thiab kev sib haum nrog cov ntawv thov thoob ntiaj teb.

Txhawm rau cov ntsiab lus Astm Cov Qauv hauv Huayang Cov Khoom Siv Hluav Taws Xob:dab tsi yog erw yeeb nkab? Nws yog ib qhohluav taws xob tiv thaiv welded steel yeeb nkabtsim los ntawm fusing steel phaj los ntawm nruab nrab - zaus Kuj kub (1kHz-3kHz), nrogERW cov yeeb nkab ntsiab lusPom loj ntau lawm rau tsawg - -} Astm cov qauv zoo li A53 thiab A36 ncaj qha tswj hwm nws cov qauv zoo. Hauv kev sib piv,HFW Steel Kav (ib qho kev sib txawv ntawmCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav) vam khomHFW lub ntsiab lus(Siab {- zaus vuam, 300khz {}} 500khz) rau kev ua haujlwm nruj rau lawv cov qauv kev ua tau zoo. Cov ntawv no tshawb txog cov lus txhais, keeb kwm, Qaum Pawg ntawm Astm cov qauv, thiab lawv cov kev siv tswv yim hauv Huayang'shluav taws xob tiv thaiv welded steel yeeb nkabntau lawm.

ASTM cov qauv yog nyob ntawm siab, kev pom zoo -} Cov ntaub ntawv tsim los ntawm cov tuam txhab tsim qauv, cov neeg siv khoom, thiab cov neeg tshawb fawb. Lawv yog tus cwj pwm los ntawm peb tus cwj pwm tseem ceeb:

Kev pom zoo -} tsav: Txhua tus qauv undergoes nyuaj los ntawm cov neeg sib txawv los ntawm cov neeg sib txawv los xyuas kom muaj kev ncaj ncees thiab kev siv tau. Piv txwv li, cov ATM A53 tus qauv rauCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kavyog tsim los ntawm pawg neeg A01 ntawm cov hlau, steel, steel, thiab cov lus tawm ntawm cov yeeb nkab cov tshuab hluav taws xob xws li Huayang thiab cov neeg siv khoom siv hauv kev lag luam thiab roj av;

Kev ua tau zoo - tsom: Tsis txhob dictating cov qauv kev tsim khoom lag luam, Astm cov qauv kev ua tau zoo (piv txwv li lub zog tensile, corrosion tsis kam) uas cov khoom yuav tsum sib ntsib. Qhov kev hloov pauv no tso cai rau Huaayang los ua kom zoo dua nwsHlobthiabHFW Steel Yeeb Nkabcov txheej txheem thaum ua kom zoo;

Pom zoo thoob ntiaj teb: Thaum tsim nyob rau hauv Asmeskas, Astm cov qauv yog los ntawm 150 lub teb chaws, ua haujlwm raws li cov lus zoo rau cov ntoo khaub lig {3} Boss kev lag luam. Huaayang'sCov Hluav Taws Xob Hluav Taws Xob Welded Hlau KavUa raws li ASTM cov qauv tau xa tawm mus rau Tebchaws Europe, thiab Sab Hnub Tuaj Asia, thiab Middle East yam tsis muaj kev sim ntxiv.

ASTM muab nws cov hauv paus rau 1898, thaum ib pawg ntawm cov engineers thiab cov kws tshawb fawb sau hauv PhilontStencies coj mus rau kev tsheb ciav hlau nquag coj mus ua kev tsheb ciav hlau. Thawj tus qauv, "Cov Qauv Txheej Txheem rau cov ntsia hlau hlau," nteg hauv av rau kev kuaj khaub ncaws sib xyaw ua ke. Raws li kev lag luam nthuav dav nthuav dav, Astm txuas txuas ntxiv nws cov qauv xaim, nrog thawj tus qauv yeeb nkab steel (ittm A53) tus qauv no tseem ceeb rau HUAYGANTHlobyeeb nkab ntau lawm.

Tshaj tawm - wwii, Astm cov qauv tau txais thoob ntiaj teb kev lag luam loj hlob. Nyob rau xyoo 1970, Astm nkag tau cov qauv rau kev siab- kev ua haujlwm kav dej zoo liHFW Steel Kav, paub txog qhov xav tau rau cov txheej txheem stricter rau nruab nrab- rau - qhov kev siv siab siab. Piv txwv li, ASTM A106 qib B (thawj zaug tshaj tawm xyoo 1955 thiab kho dua tshiab hauv 2020HFW Steel Kavmuab rau nuclear hwj chim ib kab. Niaj hnub no, Astm hloov kho cov qauv txhua 5-7 xyoo kom pom tseeb txog cov txheej txheem thev naus laus zis; Huaayang's R & D pab pawg soj ntsuam cov hloov tshiab no kom ntseeg tau nwsCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kavnyob ua ke.

ASTM cov qauv npog muaj cov ntsiab lus ntau, tab sis peb pawg yog qhov tseem ceeb tshaj plaws rau HUAYGANThluav taws xob tiv thaiv welded steel yeeb nkabKev Lag Luam: Cov Qauv Qauv (Kev txhais cov qauv hlau), cov qauv khoom lag luam (tswj cov yeeb nkab tshwj xeeb), thiab cov qauv ntsuas (tawm cov txheej txheem pov thawj).

Cov qauv khoom siv qhia txog cov tshuaj lom neeg muaj kuab lom thiab cov khoom siv zoo ntawm cov hlau siv los uaCov Hluav Taws Xob Hluav Taws Xob Welded Hlau Kav, ua kom tau cov khoom siv raw.

ASTM A36 yog qhov ntau siv cov roj carbon qauv txheem steel txheem, zoo tagnrho rau tib yamHlobCov kav dej hauv qis - rau -} nruab nrab siab siab kawg siab:
