Vuam hlau: Thaum vuam aluminium alloys siv roj vuam, tungsten arc vuam, thiab lwm yam, yuav tsum tau muab tub lim hlau. Aluminium thiab aluminium alloy vuam hlau muab faib ua ob pawg: homogeneous vuam hlau thiab heterogeneous vuam hlau. Txhawm rau kom tau txais kev sib txuas zoo welded, cov vuam hlau tsim nyog rau cov khoom siv hauv paus yuav tsum raug xaiv los ua cov khoom ntim raws li cov kev xav tau ntawm cov khoom siv welded.
Thaum xaiv vuam hlau, koj yuav tsum xub xav txog qhov yuav tsum tau muaj ntawm cov khoom siv vuam, nrog rau cov khoom siv kho tshuab, kev tiv thaiv corrosion, cov qauv rigidity, xim thiab tawg tsis kam ntawm cov khoom. Xaiv cov hlau muab tub lim nrog qhov kub qis dua li lub hauv paus hlau tuaj yeem txo qhov kev nyiam ntawm cov kab nrib pleb hauv thaj tsam kub ntxhov. Rau qhov sib koom ua ke lub zog ntawm cov hlau tsis muaj cua sov, lub zog nce hauv qhov kev txiav txim ntawm 1000 series, 4000 series, thiab 5000 series.
