Qhov tooj dag soldering muaj zog npaum li cas?

Koj muaj ib qhov project uas yuav tsum tau welding tooj dag. Cov tooj dag puas tuaj yeem welded zoo? Peb paub qhov tseeb txog nyiaj Welded Brass.

Muaj peev xwm paub yuav ua li cas vuam tooj dag. Ua ntej ntawm tag nrho cov, koj yuav tsum xyuas kom meej tias qhov project nto yog huv si, thiab ces paub meej tias qhov nruj haum. Thaum kawg, siv txoj cai tooj dag solder thiab lub teeb hluav taws xob tsawg. Yog tias koj siv cov khoom siv tsis raug, nws yuav ua rau impurities hauv cov khoom thiab txawm tias koj cov khoom puas.

Vuam tooj dag tsis tas yuav nyuaj. Peb yuav coj koj mus rau tag nrho cov txheej txheem. Thaum koj kawm yuav ua li cas weld tooj dag zoo, koj yuav pom tias nws yooj yim rau vuam lwm yam khoom siv hlau.

Koj yuav tsum paub cov ntaub ntawv hlau uas koj siv. Cov hlau sib txawv muaj cov ntsiab lus sib txawv. Brass yog suav tias yog cov hlau tsis muaj cua sov. Thaum vuam, cov cua sov tsim nyog yuav tsum tau siv kom cov hlau tsis raug yaj lossis deformed. Koj kuj yuav tsum tau siv txoj cai flux thiab solder rau koj qhov project.

Qee cov hlau, xws li tooj dag, yog alloys. Qhov no txhais tau hais tias lawv yog cov tebchaw uas ob lossis ntau dua hlau sib xyaw ua cov hlau tshiab.

Brass yog ua los ntawm "txawv proportions ntawm tooj liab thiab zinc". tooj dag kuj muaj lwm yam hlau, xws li txhuas thiab qee zaum arsenic. Vim lawv yuav tsum tau ua tooj dag. Muaj ntau tshaj 60 hom tooj dag. Peb yuav tsom mus rau cov hauv qab no feem ntau siv tooj dag alloys:

C360 tooj dag lossis dawb txiav tooj dag feem ntau yog siv rau cov kav dej thiab cov khoom siv kho tshuab. Nws muaj cov ntsiab lus txhuas siab thiab yog ib qho ntawm cov tooj dag uas yooj yim tshaj plaws rau vuam, tab sis nws tsis haum rau cov ntaub ntawv uas nkag mus rau hauv tib neeg lub cev.

C330 tooj dag los yog tooj liab tsis tshua muaj hlau lead yog cov khoom siv zoo tshaj plaws rau cov kav dej thiab qhov chaw dej. Nws muaj cov ntsiab lus tsis tshua muaj hlau lead thiab corrosion kuj. Nws yog ib qho khoom siv feem ntau siv

tooj dag siv rau hauv cov hniav nyiaj hniav kub thiab cov ntaub ntawv kho kom zoo nkauj yog hu ua C260 lossis cylindrical tooj dag. Nws muaj cov ntsiab lus siab ntawm zinc thiab tooj liab. Qhov no tooj dag alloy txuas tau yooj yim tsis poob lub zog. Cov mos txwv tooj dag tsis muaj txhuas. Nws tshwm sim nyob rau hauv tsuas yog ob qhov chaw, ib qho rau cov nplua nuj thiab lwm qhov rau kev sib ntaus sib tua.
