Handheld laser welding and argon arc welding comparison
1. In comparison to traditional arc welding, a handheld laser welding machine can save approximately 80% to 90% of electrical energy, and it can also reduce processing costs by about 30%.
2. When comparing the welding effects, handheld laser welding is capable of welding metal and dissimilar metals together. It offers fast speed, minimal deformation, and a small heat-affected zone. The welding seam appears beautiful and flat, with little to no porosity and no pollution. Additionally, the handheld laser welding machine can perform precise welding and handle tiny open parts.
3. In terms of subsequent processes, handheld laser welding results in low heat input and minimal deformation of the workpiece, leading to a visually appealing welded surface. Depending on the desired effect, minimal or no additional treatment may be required. This significantly reduces the need for labor-intensive processes such as polishing and leveling, resulting in cost savings.
