Laser Welding FAQs
Laser welding¹ utilises a highly concentrated light energy beam, known as a laser, to weld metals together. The beam is generated by a focused laser source directed on the metal using optical components.
Intense heat generated by the laser beam melts the metal, creating a weld pool, that forms a strong and durable bond or weld.
Today we’re covering off some frequently asked questions regarding laser welding.
Is laser welding as strong as MIG welding?
Yes. Due to the intense heat and resulting weld pool, laser welding typically stronger than MIG welding. A laser weld is also achieved up to 5 times faster, without the need for multiple processes which can result in a weaker weld.
What is laser welding used for?
Laser weld applications are increasing in popularity and use. Often used in the automotive industry, laser welding is also utilised in:
- Aerospace
- Government
- Rail
- Electronics
- medical devices, and more.
What is the cost of laser welding?
Although specialist equipment, skills and reflected light-proof spaces are required for laser welding, it’s a cost effective choice for metal fabrication due to its speed, strength and durability, when compared to MIG welding. The cost for laser welding is determined on a project basis. If you’re interested in a quote, please contact our specialist team today.
