Flash taub qab vuam yog cov txheej txheem ua tau zoo siv hauv ntau qhov kev lag luam rau kev koom nrog cov hlau. Nyob rau hauv cov txheej txheem vuam no, muaj ob txoj kev sib txawv: nruam flash welding thiab preheat flash welding. Kev nkag siab txog qhov sib txawv ntawm cov txheej txheem no yog qhov tseem ceeb rau kev ua tiav cov welds meej thiab txhim khu kev qha.
Nruam flash welding, raws li lub npe qhia, muaj kev txuas ntxiv ntawm lub teeb thiab kub thaum lub vuam txheej txheem. Txoj kev no yog qhov tshwj xeeb zoo rau kev koom nrog cov hlau zoo sib xws thiab muaj pes tsawg leeg. Nws yog tus cwj pwm los ntawm kev siv tas li ntawm cov hluav taws xob tam sim no thiab lub siab, uas tsim kom muaj lub teeb nyem txuas ntxiv ntawm qhov cuam tshuam ntawm cov workpieces. Lub flash nyob rau hauv tas li flash welding pab lub hom phiaj ntawm melting thiab fusing cov hlau xaus ua ke, uas ua rau ib tug muaj zog thiab zoo ib yam weld.
Ntawm qhov tod tes, preheat flash welding yog ib qho txheej txheem uas suav nrog kev tawg luv luv ntawm kev kub siab thaum pib ntawm txoj kev vuam. Qhov pib tawg ntawm cov cua sov no, hu ua preheating flash, yog siv los ua kom qhov kawg ntawm cov khoom ua haujlwm, ua rau lawv zoo dua thiab npaj tau rau cov vuam tom ntej. Preheat flash vuam yog tshwj xeeb tshaj yog muaj txiaj ntsig thaum koom nrog cov hlau tsis sib xws lossis cov khoom ua haujlwm nrog cov thicknesses sib txawv. Kev tswj kev siv cov cua sov hauv lub preheating theem txo qhov kev pheej hmoo ntawm thermal stress thiab distortion nyob rau hauv kawg weld.
Hauv cov ntsiab lus, qhov sib txawv ntawm qhov txuas txuas txuas flash thiab preheat flash welding yog nyob rau lub sijhawm thiab lub sijhawm ntawm kev siv cua sov. Nruam flash welding tuav ib daim ntawv thov tas li ntawm cov cua sov thoob plaws hauv cov txheej txheem vuam, ua rau nws tsim nyog rau kev koom nrog cov ntaub ntawv zoo sib xws. Nyob rau hauv sib piv, preheat flash welding pib nrog ib tug luv luv tawg ntawm khaus kub los npaj lub workpieces rau vuam, ua rau nws zoo tagnrho rau kev koom nrog cov khoom sib txawv los yog txawv thicknesses.
Ob txoj kev muaj lawv qhov zoo thiab kev siv, thiab kev xaiv ntawm lawv yog nyob ntawm cov kev cai tshwj xeeb ntawm txoj haujlwm vuam. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau cov welders thiab engineers kom paub cov kev txiav txim siab thiab xyuas kom meej tias kev ua tiav ntawm flash pob tw vuam ua haujlwm.
