Advertising Industry
The main requirements for welding in the advertising industry are: good appearance, precise welding, high controllability, etc. Handheld laser welding has a small heat-affected zone during welding, which will not cause deformation or blackening of the workpiece, and the weld seam is beautiful. At the same time, the power control is accurate, the focused spot is small and the positioning accuracy is high, and it can be widely used in advertising welding scenarios.
On-site installation and repair of large metal letters/logos
| Comparison Items | Traditional Argon Arc Welding Solution | Laser Welding Solution |
|---|---|---|
| Heat input | Higher (5 times that of laser welding) | Lower (only 1/5 of that of argon arc welding) |
| Splicing misalignment | ＞2mm | ＜1mm |
| Temperature rise of back paint | ＞200℃ | Only 40℃ increase |
| Weld treatment requirement | Needs grinding and polishing, with high difficulty in high-altitude construction | No grinding required; welds are naturally smooth, eliminating high-altitude polishing process |
| Thermal deformation | Causes large-area thermal deformation, leading to font distortion | Zero-deformation welding |
| Welding depth range | – | 0.1-1.2mm |
| Applicability for high-altitude operations | Less applicable due to complex procedures and large heat impact | Highly applicable with direct welding via handheld operation |
