Vim li cas peb yuav tsum tau preheat 150-300℃ua ntej vuam?
Preheating tuaj yeem ua kom qeeb qeeb qeeb qeeb qeeb hauv cov hlau hluav taws xob siab (xws li, 120℃{}} Thermocouple soj ntsuam yog yuav tsum tau Thaum lub caij cua sov hauv zos, thiab qhov sib txawv ntau dhau yuav ua rau muaj kev ntxhov siab ntau dhau.
Dab tsi yog qhov zoo ntawm laser vuam dhau Tig vuam?
Cov cua sov cuam tshuam thaj tsam ntawm laser vuam tsuas yog {mm} Kuv tau nyiaj txiag yog li 3 lab nyiaj txiag yog qhov yuav tsum tau ua ± 0 {{{{{}} 05mm {{6Ä}} kw fiber ntau laser refers tau tau siv dav hauv lub teb chaws aerospace.
Yog tom qab kev kho cua sov-weld (duab) tsim nyog?
PWHT yuav tshem tawm cov chaw muaj kev ntxhov siab rau vuam thiab txo qhov nyuaj rau hauv qab 22hrc kom tsis txhob muaj kev ntxhov siab, ASME} 2 {}}}}} yuav tsum tau yauv yauv mus. Lub sijhawm tuav tau suav nrog rau phab ntsa tuab (1h / nti), thiab ntsuas qhov ntsuas kub qhov muag yuav tsum yog li ntawm ± 14 degree.
Tuam kev xaiv rau tig siab-hardness Alloy steel?
Nws raug nquahu kom siv CBN cov cuab yeej los ua cov txheej txheem nrog HRC> 50, thiab cov chips} tag nrho cov nqi ua .
Yuav ua li cas kom tsis txhob ua haujlwm hnyav thaum lub qhov tob?
Siv cov kauj ruam pub rau sab nraud (pub rau ib qho kev txiav txim siab (xws li cov roj tawg) hardening txheej> 0 . 1mm.
