What type of welding machine laser should I choose?

In this article, we will take some time to explain the best way to choose a laser welding machine from four key perspectives, depending on the type of laser. Please refer to the following items after understanding the applications required by your company and the materials used.

1.Commonly used industries and materials

With numerous types of materials available, it’s crucial to consider your industry and the materials your company deals with when selecting a laser welder. Before making a decision, consider the laser welding machine’s ability to accurately and precisely handle a wide range of materials.

	Suitable Materials	Industry
CO2 Laser	Nonferrous metals (aluminum, copper), steel, stainless steel	Automotive industry, aerospace industry, Heavy industry
YAG Laser	Iron, stainless steel, titanium, alloy	Medical equipment manufacturing, electronic equipment manufacturing, Precision engineering
Fiber Laser	Almost all metals (steel, stainless steel, aluminum, titanium, copper, etc.)	Automotive industry, electronic equipment manufacturing, General industry
Disc Laser	Stainless steel, steel, titanium, non-ferrous metals	Aerospace industry, automotive industry, Medical device manufacturing
Semiconductor Laser	Light metals, thin sheet metals, plastics	Electronic equipment manufacturing, small parts manufacturing, Medical equipment manufacturing

2.Characteristics and Suitable Welding Applications

Depending on the welding method employed, the surface may show signs of burning. When selecting a laser welding machine, understanding your company’s performance needs is paramount. If you take time to properly examine the functional characteristics of the laser type to ensure it delivers the desired results, you will have made a good investment.

	Functional features	Appropriate use
CO2 laser	High energy efficiency deep penetration power	Suitable for welding thick materials Enables uniform welding in large area welding work
YAG laser	Compatible with various metals Good at fine welding	High precision and fine welding Suitable for small parts and precision equipment
Fiber laser	Excellent beam quality high energy density	Beautiful and precise welding possible Suitable for thin to medium-thick plates
Disc laser	High beam quality and power Precise and deep penetration power	High quality and uniform welding possible Suitable for metal processing
Semiconductor laser	Relatively low output Capable of welding small, lightweight parts	Suitable for fine parts and thin materials High precision, welding with not too deep penetration possible

3.Ease of use and maintenance

When picking a laser welding machine, it is important to make a choice keeping in mind the ease of access and ability to maintain and handle the equipment at your factory or location. Let us take a look at a few prospective options.

	Ease of use	Maintenance
CO2 Laser	Complex compared to others It may be necessary to adjust the optical system	Cleaning and adjusting optical components Regular laser gas replacement
YAG Laser	Simple compared to others Requires precise setup	Regular replacement of lamps Particular attention should be paid to the lamp life.
Fiber laser	Relatively easy and intuitive operation Easy automation and integration	Almost maintenance free Regular inspection of fiber cables and lenses
Disc Laser	Requires more advanced operation than others High stability once set up	Regular cleaning and adjustment of optical components Overall maintenance is relatively easy
Semiconductor Laser	Often small and easy to operate Handheld type also available	Low Maintenance Parts may need to be checked or replaced

4.Production Efficiency

Production efficiency also varies depending on the type of laser. Choose a welding machine that will give you the maximum efficiency you are looking for, while considering whether it will integrate well with your existing systems.

	Advantages in production efficiency	Disadvantages in production efficiency
CO2 Laser	Suitable for mass production Suitable for non-ferrous metals (aluminum, copper), steel, stainless steel, etc.	As large equipment is required, it takes time to install and set up.
YAG Laser	Good efficiency for small-scale products Suitable for iron, stainless steel, titanium, alloys, etc.	Maintenance such as lamp replacement takes time.
Fiber Laser	Suitable for mass production as rapid welding is possible Compatible with almost all metals (steel, stainless steel, aluminum, titanium, copper, etc.)	May not be suitable for thick materials
Disc Laser	Suitable for complex welding operations, Efficient once in operation Suitable for stainless steel, steel, titanium, non-ferrous metals, etc.	Setup requires specialized knowledge
Semiconductor Laser	High efficiency for small-scale products Suitable for light metals, sheet metals, plastics, etc.	Not very suitable for mass production
