Advantages and disadvantages of laser welding
Laser welding                or laser beam welding is a process that uses a laser-focused heat source to melt materials. Laser welding operates in two fundamentally different modes: conduction-limited welding and deep-hole welding. The mode of interaction of the laser beam with the material it is welding will depend on the power density at which the beam hits the workpiece. The working principle of laser welding is to focus a high-power-density laser and apply heat to the joint between two metal surfaces. When the metal surface absorbs the laser, the material is heated and melted to form a weld between the two surfaces to complete the welding.     
 
Laser welding has higher welding precision and quality. Since the laser itself generates very little heat, the weld seam produced after laser welding is also relatively small, which makes laser welding especially suitable for thinner materials, such as electronics or glass/metal seals. Whereas when welding thicker materials, narrow and deep welds are produced between square-edged parts. Today, modern laser welding applications incorporate advanced optics that allow the use of programmable robots to pinpoint an area in the workpiece.     
 
Fiber Laser Welding Advantages               
Laser welding is a modern-day technology that uses high-powered lasers to fuse metal, thermoplastics, and composite workpieces. Starting in the 1990’s it has continuously evolved, thus making industrial manufacturing better. It’s much faster, more precise, cost-effective, eco-friendly, and user-friendly than traditional welding. Most importantly, it’s compatible with modern automation and the ever-growing need for higher quality and intricate products. Laser Welding is also easier to master.     
 
Advantages and disadvantages of laser welding
Laser precision allows for better quality welds, faster throughput, reduced post-processing costs and access to new domains of application.
 
The main drawback of laser welding is the hefty price tag for the equipment. Our accurate measurement solutions help you maximize the ROI of this investment.     
 
Let’s discuss about the main advantages and disadvantages of laser welding.
 
Advantages of laser welding
Minimal thermal impact on the surrounding surfaces
Welding, both traditional and laser-based, implies heat delivery at the junction between two surfaces. The melted metals mix and, after they’ve cooled, form a strong bond, effectively joining the two components together.
