Raws li lub melting point ntawm lub solder, brazing yog muab faib ua ob pawg: mos soldering thiab nyuaj soldering.
(1) Soldering.
Soldering qhov twg lub melting point ntawm lub solder yog qis dua 450 degree yog hu ua mos soldering. Cov khoom siv feem ntau yog tin-lead solder, uas muaj cov dej ntub dej zoo thiab cov khoom siv hluav taws xob thiab tau siv dav hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab qhov chaw pib. Lub zog ntawm cov pob qij txha welded feem ntau yog 60-140MPa.
(2) Brazing
Soldering nrog lub melting point ntawm solder siab tshaj 450 degree yog hu ua brazing, thiab feem ntau siv solders yog tooj dag solder thiab nyiaj-raws li solder. Cov pob qij txha siv nyiaj-raws li solder muaj lub zog siab, conductivity, thiab corrosion kuj. Solder muaj qhov tsis tshua muaj melting point thiab ua haujlwm zoo, tab sis tus nqi ntawm cov solder yog siab, thiab nws feem ntau yog siv rau cov khoom uas yuav tsum tau vuam siab. Siv tooj dag solder. Brazing feem ntau yog siv rau steel thiab tooj liab alloy workpieces nrog kev ntxhov siab, nrog rau cov cuab yeej brazing. Lub zog sib koom ua ke ntawm brazing yog 200 txog 490 MPa.
