Lub cev essence ntawm hlau vuam

Thaum lub sij hawm vuam txheej txheem, lub workpiece thiab solder yaj los ua ib tug molten cheeb tsam, thiab tom qab lub molten pas dej ua ke txias thiab solidifies, nws tsim ib tug kev sib txuas ntawm cov ntaub ntawv. Thaum lub sij hawm tus txheej txheem no, lub siab feem ntau yog siv. Muaj ntau qhov chaw ntawm lub zog rau vuam, nrog rau cov pa taws, hluav taws xob arcs, lasers, electron beams, kev sib txhuam, thiab ultrasonic tsis. Ua ntej kawg ntawm lub xyoo pua puv 19, tsuas yog cov txheej txheem vuam siv los ntawm cov kws ua hlau rau ntau pua xyoo yog hlau forging vuam. Cov txheej txheem vuam niaj hnub ua ntej tshaj plaws tau tshwm sim nyob rau hauv lub xyoo pua puv 19, thawj arc vuam thiab cov pa roj welding, thiab tom qab vuam vuam. Thaum pib ntawm lub xyoo pua 20th, nrog rau kev tawm tsam ntawm Ntiaj Teb Tsov Rog I thiab II, muaj kev xav tau zoo rau kev sib txuas ntawm cov khoom siv tub rog uas pheej yig thiab txhim khu kev qha, uas txhawb kev txhim kho vuam tshuab. Niaj hnub no, nrog kev siv cov vuam neeg hlau dav dav hauv cov ntawv thov kev lag luam, cov kws tshawb fawb tseem tab tom delving rau hauv cov ntsiab lus ntawm vuam thiab txuas ntxiv tsim cov txheej txheem vuam tshiab los txhim kho vuam zoo.

Lub cev essence:
Vuam yog txheej txheem uas ob lossis ntau cov ntaub ntawv ntawm tib yam lossis ntau hom tau koom ua ke los ntawm atomic lossis molecular bonding thiab diffusion.
Cov txheej txheem ntawm kev txhawb nqa kev khi thiab kev sib txawv ntawm cov atoms thiab cov molecules yog cua sov los yog pressurization, los yog ob qho tib si cua sov thiab pressurization ib txhij.
