Material Compatibility: Commonly welded materials include steel, aluminum, stainless steel, titanium, and various alloys. Surface Finish: A clean surface allows the laser beam to reflect off the material, creating a strong weld. Workpiece Alignment: Alignment is crucial to ensure the laser beam hits the desired spot and the weld is formed correctly. Joint Preparation: The joint area where the weld is to be formed should be prepared appropriately. Creating a V-shaped or U-shaped groove, and ensuring a good fit between the two workpieces.
