What Metals can be Successfully Welded with Fiber Lasers?

Laser metal welding is just one of the many laser-based processes, which can be completed with a fiber laser. In this application, the laser beam is targeted to melt two metallic objects together to create a strong, durable and permanent join between them. We are focusing on metal in this article, but laser welding can be used on a wide variety of other materials too.

Popular metals for laser welding

There are a vast selection of metals, which can be fiber laser welded, amongst the most popular are:

  • Aluminium – there are a wide number of uses for aluminium, such as in battery production (an increasingly popular application with the advent of e-mobility)
  • Brass – fiber lasers are particularly effective at welding brass where back reflections are a common issue
  • Copper – this is frequently welded in many industries, such as in semi-conductors production
  • Gold – retaining the aesthetic appeal is all important when working with gold, fiber lasers can help with the creation of seamless welding joints in jewellery pieces
  • Nickel alloy – a range of nickel alloys are used in many industries, in particular chemical industries such as desalination and nickel alloy tubing pipes
  • Silver – fiber lasers can be used to create seamless joins in silver, which can be used in jewellery
  • Steels – a variety of different steel types including carbon, stainless and tool steels all benefit from fiber laser related welding processes
  • Titanium – renowned for its strength and when combined with its light weight, titanium is increasingly used in the Aerospace and Automotive industries, where (virtually) invisible welding joints are highly desired

Video: Working with dissimilar metals

Many metals don’t naturally want to be welded together (e.g. Copper and Aluminium), they will have different mechanical and/or chemical properties which resist each other. There are a large number of industrial applications for dissimilar metal welding, such as welding lithium-ion battery cells, the process is popular in Automotive and the Electronics industry in particular. Fiber lasers can be used to create strong, permanent welding joins between metals which would be difficult to weld through traditional techniques.
