About Spot / Laser Welding Technique
Spot Welding is one of the most widely used joining methods in mass production industries, especially automotive manufacturing. It works by clamping two or more metal sheets between electrodes and passing a strong current through them, which creates localized heat and fusion at the contact point. It is fast, reliable, and ideal for high-volume production lines.
Laser Welding, on the other hand, utilizes a focused high-energy laser beam to melt and fuse materials. Compared to spot welding, it provides deeper penetration, narrower weld seams, higher precision, and the ability to weld complex geometries.
When combined with robotic systems, both spot and laser welding offer:
- High repeatability,
- Fast cycle times,
- Consistent weld quality,
- Seamless integration into automated production cells.
Spot / Laser Welding Advantages
