Ntawm no yog cov ntsiab lus ntawm 10 feem ntau cov teeb meem nrogVuam 4130 chromium-molybdenum khoomsiv TIG welding.
Cov ntawv sau no tsuas yog siv rau kev ua kis las, xws li cov qauv dav hlau, cov tsheb sib tw, cov ncej los tiv thaiv, cov xuab zeb tsheb kauj vab, tsheb kauj vab, thiab maus taus thav duab, thiab lwm yam.
Q: 4130 chromium-molybdenum khoom puas tuaj yeem welded los ntawm argon arc vuam?
A: Yog, TIG vuam ntawm4130 CrMo khoomtau siv nyob rau hauv kev lag luam aerospace tau ntau xyoo. Raws li nrog tag nrho cov vuam, TIG vuam yuav tsum tau ua raws li cov txheej txheem suab thiab cov txheej txheem.
Q: Kuv puas yuav tsum tau preheat?
A: Thin-walled yeeb nkab (tsawg dua 0.12" lossis 3mm tuab) feem ntau tsis tas yuav tsum tau 300-400 degree F (kwv yees 149-204 degree) ntawm preheating kom ua tiav cov txiaj ntsig xav tau. Txawm li cas los xij, lub raj kub ntawm tus kheej yuav tsum tsis txhob qis dua 70 degrees Fahrenheit (kwv yees li 21 degrees Celsius) siab dua chav sov ua ntej vuam.
Q: Kuv yuav siv cov vuam hlau zoo li cas?
A: Txawm hais tias muaj ntau txoj hauv kev rau cov xaim zoo, tsis muaj kev xaiv zoo dua li ER80S-D2, uas ua rau lub vuam seam zog ze rauzog 4130, los yog ER70S-2, uas yog me ntsis qaug zog.
Q: Yog tias kuv siv ER70S-2 xaim, kuv puas tau txi lub zog kom tau txais kev zoo dua?
A: Yog lawm, thaum cov hlau fused rau hauv cov khoom siv hauv paus, lub zog ntawm cov hlau feem ntau tsawg dua li ntawm 4130. Txawm li cas los xij, los ntawm kev tsim qauv tsim nyog (xws li ntxiv qhov txhawb nqa los yog kev txhawb nqa lub raj) ntau qhov kev txhawb nqa thiab ntev vuam seam. tuaj yeem ua rau qhov tsis muaj zog ntawm cov hlau nws tus kheej.
Q: Vim li cas 4130 hlau tsis pom zoo?
A: 4130 hlau feem ntau yog siv rau cov khoom ua haujlwm uas yuav raug kho kom sov hauv cov txheej txheem tom qab. Nws tsis pom zoo siv rau hauv cov khoom siv ua kis las xws li dav hlau, kev sib tw thav duab, thiab cov thav duab vim nws qhov siab tawv thiab tsis muaj ductility.
Q: Kuv puas tuaj yeem siv lwm cov vuam hlau rau 4130?
A: Qee tus tswv nyiam siv austenitic stainless hlau xaim rauweld 4130 steel yeeb nkab. 310 thiab 312 qib stainless hlau hlau kuj tseem siv tau. Lwm qib ntawm stainless hlau tuaj yeem ua rau tawg, thiab stainless hlau xaim feem ntau kim dua.
Q: Kuv puas yuav tsum tau kho cov 4130 workpieces kom txo tau kev ntxhov siab tom qab vuam?
A: Nyias-walled hlab feem ntau tsis tas yuav muaj kev ntxhov siab, phab ntsa thickness ntau dua 0.12" lossis 3mm cov khoom siv welded tom qab kev kho cua sov zoo tshaj plaws, qhov kev kho kub zoo tshaj plaws rau cov yeeb nkab fittings yog 1100 degrees Fahrenheit (txog 593 degrees Celsius), oxygen thiab acetylene los ua cov nplaim nruab nrab tuaj yeem siv los ua kom sov cov txheej txheem cua sov kom txav mus kom tsis txhob muaj cua sov hauv zos.
Q: Kuv puas yuav tsum tau ntxuav 4130 cov khoom ua ntej vuam?
A: Cov impurities thiab roj nyob rau saum npoo ntawm cov yeeb nkab steel yuav tsum tau muab ntxuav tawm nrog cov ntawv xuab zeb nruab nrab thiab acetone, burrs thiab kaum cov lus qhia yuav tsum tau polished, ib qho kev sib cuag ntawm qhov chaw yuav ua rau cov txiaj ntsig zoo dua.
Q: 4130 khoom weldingrov qab los tiv thaiv roj?
A: Feem ntau tsis tas yuav vuam rov qab roj tiv thaiv, txawm hais tias qee tus tswv kuj ua li ntawd, kev tiv thaiv roj rov qab tsis zoo rau vuam, thiab rau qee qhov vuam yuav txhim kho vuam zoo ntawm cov vuam channel.
Q: Lub welded workpiece puas tuaj yeem hardened?
A: Tsis yog, quenching ceev ntawm welded workpieces tuaj yeem ua rau muaj ntau yam teeb meem, xws li tawg los yog delamination kua muag, thiab lub workpiece yuav tsum tau tso cai kom txias lawm.
