The copper tube welding process is to radiate the copper tube bundle with excellent directivity， high brightness， high strength， high monochromaticity， high coherence and other characteristics to the surface area of the workpiece to be processed. After the copper tube bundle is focused by the optical system，브 레 머321 스테인리스강 권재， through the interaction between the copper tube and the object to be welded， a highly concentrated heat source area can be formed at the place to be welded in a very short time. The heat energy makes theea to be welded melt， cool and crystallize to form a solid welding spot and weld seam.
