Cov cim qhia ntawm oxyacetylene vuam zoo suav nrog cov hlaws zoo li tsis muaj qhov lossis globules ntawm cov hlau yaj. Ib qho tsis zoo oxy weld yuav muaj qhov thiab tsis muaj qhov sib xws. Koj tseem yuav pom qhov nkag tsis txaus ntawm cov workpieces. Tsis tas li ntawd, tuaj yeem muaj cov hlau nplaum loj ntawm thiab nyob ib ncig ntawm lub vuam.
Yuav ua li cas yog qhov zoo ntawm weld?
Cov xwm txheej ntawm vuam zoo kom ua tiav cov khoom zoo li no suav nrog cov hauv qab no:
- Tsis muaj kab nrib pleb lossis qhov pom hauv cov hlaws.
- Cov hlaws muaj cov nthwv dej sib xws, dav thiab qhov siab.
- Cov khoom tiav txaus siab rau qhov tsim qhov ntev thiab yuav luag tsis muaj kev cuam tshuam.
- vuam ua tau raws li qhov xav tau lub zog.
5 yam tseem ceeb rau kev vuam zoo yog dab tsi?
Kev ceev nrawm yog cuam tshuam los ntawm hom vuam tam sim no (DCEN, DCEP lossis AC), amperage, vuam txoj haujlwm, electrode yaj tus nqi, cov khoom tuab, qhov chaw ntawm lub hauv paus hlau, hom kev sib koom ua ke, sib koom ua ke thiab electrode manipulation.
Yuav ua li cas ua kom zoo vuam?

Nyob rau hauv oxyacetylene roj vuam nplaim kub yog?
Oxyacetylene vuam, feem ntau hu ua roj vuam, yog txheej txheem uas tso siab rau kev sib txuas ntawm oxygen thiab acetylene. Thaum muab sib xyaw ua ke hauv qhov sib npaug ntawm tes tuav lub teeb lossis lub tshuab raj, cov nplaim hluav taws kub yog tsim nrog qhov kub ntawm kwv yees li 3, 200 deg.
Yuav tsum muaj qhov tseem ceeb hauv qhov zoo lossis qhov tsis zoo?
Qhov feem cuam tshuam ib txwm muaj yog 1.21 txog 1.52 AU / ml. Qhov kev ntsuam xyuas yuav qhia rau koj seb koj puas kuaj qhov zoo lossis tsis zoo rau Intrinsic factor blocking antibody lossis Intrinsic factor binding antibody. Tsawg dua 1.20 AU / mL raug suav tias yog qhov tsis zoo thiab ntau dua 1.
Muaj pes tsawg qhov zoo ua rau qhov tsis zoo?
Raws li kev tshawb fawb, qhov zoo tshaj plaws qhuas-rau-kev thuam yog 5: 1. Lub ntsiab lus, rau txhua qhov kev tawm tswv yim tsis zoo uas koj ua, koj yuav tsum qhia tsib nqe lus zoo ib yam. Thawj qhov kev tshawb fawb los ntawm Emily Heaphy thiab Marcial Losada IDed qhov 5:
Qhov twg yog qhov zoo lossis qhov tsis zoo skewness?
A txhais tau tias nrog qhov zoo skew yog qhov zoo, thaum lub ntsiab lus tsis zoo nrog qhov zoo tsis zoo. … Nyob rau hauv xaus, lub skewness coefficient ntawm ib pawg ntawm cov ntaub ntawv cov ntsiab lus pab peb txiav txim siab tag nrho cov duab ntawm lub faib nkhaus, seb nws zoo los yog tsis zoo .
Puas yog hluav taws xob ntws los ntawm qhov zoo mus rau qhov tsis zoo?
Cov ntws ntawm electrons yog hu ua electron tam sim no electron tam sim no Lub SI unit ntawm hluav taws xob tam sim no yog lub ampere, los yog amp, uas yog qhov ntws ntawm hluav taws xob hla ib qho chaw ntawm qhov chaw. tus nqi ntawm ib coulomb ib ob.
