Raws li qhov kev txhim kho kev lag luam tam sim no, kev siv cov khoom siv raw rau aluminium alloy profiles yog qhov ntau thiab ntau dua. Raws li qhov yuav tsum tau vuam ntawm aluminium alloy profiles tau txais ntau dua thiab ntau dua, tab sis nws yog qhov nyuaj dua rau kev sib txuas ntawm cov txhuas hlau txhuas, yog li peb yuav tsum daws cov teeb meem thiaj li ua kom YAG hlau laser vuam tshuab siv tau ntawm aluminium alloy profile raw cov ntaub ntawv sai li sai tau li sai tau.
2 teeb meem ntawm aluminium alloy profile nyob rau hauv cov hlau laser vuam tshuab:
1. Aluminium yog tus cwj pwm zoo kub thiab hluav taws xob. Cov khoom siv hluav taws xob pub dawb ua rau nws ua kom zoo nkauj ntawm lub teeb. Qhov sib kis ntawm cov chaw saum thiab hauv qab siab tshaj 90%. Qhov no yuav tsum muaj lub zog siv hluav taws xob siab kom ntseeg tau tias lub vuam yuav tsum pib thaum pib. Lub zog tseem ceeb.
2. Raws li qhov kub nce mus, solubility ntawm hydrogen hauv txhuas yog nthuav dav heev, thiab hydrogen yaj hauv nws los ua qhov chaw ntawm kev tsis txaus nyob rau hauv vuam. Muaj cov pa ntawm lub sijhawm thaum vuam, cov kab nrib pleev yuav tshwm ntawm lub hauv paus thaum sib sib zog nqus arc vuam, thiab txoj kev tsim weld tsis muaj zog.
