Vuam ntawm tooj liab thiab tooj liab alloys mig vuam hlau
1. Cov tooj liab ntshiab (tooj liab) yog dab tsi?
A: Cov khoom siv tooj liab nrog cov ntsiab lus tooj liab Ntau dua lossis sib npaug li 99.9% yog hu ua tooj liab ntshiab (tooj liab).
Qib: C10200, C11000, C12000, C12200, thiab lwm yam.
Vuam hlau nab npawb: HS201
2. Dab tsi yog qhov tooj liab alloy? Lawv cais li cas?
A: Ntxiv zinc ( tooj dag), npib tsib xee (nickel), silicon (silicon bronze), txhuas rau tooj liab
(aluminium bronze), tin (tin bronze), phosphorus (phosphor bronze), thiab lwm yam hu ua tooj liab alloys. kev faib tawm
raws li nram no:
<1>Phosphor Bronze (C50500) Vuam Hlau: HS202
<2>Silicon Bronze (C65100) Vuam Hlau: HS211
<3>Aluminium Bronze (C61300) Vuam Hlau: HS214
<4>Brass (C21000) Vuam Hlau: HS221
<5>Brown tooj liab (C70600)
3. Vim li cas MIG vuam tooj liab (tooj liab) yuav tsum tau preheat 400--600 degree ua ntej vuam?
A: Lub siab thermal conductivity ntawm tooj liab (7 mus rau 11 npaug loj dua hlau) ua rau nws nyuaj rau lub hauv paus hlau thiab muab tub lim hlau.
Hauv fusion, muaj qhov tshwm sim uas qhov vuam tsis tuaj yeem ua tau thiab qhov vuam tsis ua. Preheating ua ntej vuam 400 ~ 600 degree
Ua kom lub workpiece tau txais cua sov txaus los xyuas kom meej qhov zoo ntawm cov vuam kom ua tiav cov vuam zoo li qub.
4. Yog vim li cas cov ntshiab tooj liab weld ua rau kub tawg?
A: Sulfur, phosphorus, tin, zinc thiab lwm yam tsawg-melting eutectics ua rau tooj liab thiab tooj liab alloys pom tseeb thaum tshav kub kub brittleness, weld pob qij txha yog nquag kub tawg. Thiab qhov nyiam ntawm qhov vuam qhov cua yog muaj zog dua steel Hnyav thiab ntau dua.
5. MIG brazing vuam yog dab tsi?
A: Kev siv cov tooj liab uas tsis tshua muaj melting tooj liab hlau solder (xws li: silicon bronze, aluminium bronze, thiab lwm yam.)
Ntshiab argon tiv thaiv roj hlau arc vuam - hu ua MIG brazing. Nrog hlau melting
Fast, arc stability, ntiav nkag, ceev vuam ceev thiab lwm yam txheej txheem nta. Tswj vuam
Thaum tshav kub kub input yog qis tshaj, lub hauv paus hlau tsis yaj; hlau sai melts thiab nkag mus rau hauv qhov sib txawv weld
, ua ib qho kev sib koom ua ke. High weld lub zog, me me workpiece tshav kub cuam tshuam cheeb tsam, nyias daim ntawv tom qab weldingDeformation. Haum rau welded lub cev phaj pob qij txha, ceg tawv pob qij txha nrog phaj thickness δ=0.8 ~ 2 hli Cov pob qij txha thiab cov chaw welds yog dav siv rau kev vuam ntawm lub tsheb lub cev thiab plated steel daim hlau.
