Laser vs. TIG/MIG: How Much Can You Really Save on Welding?

How Much Can You Really Save on Welding?

More and more companies are switching from TIG or MIG/MAG welding to laser technology today. The reason is not only weld quality, but also time savings, lower costs, and higher production efficiency.

Why Companies Are Switching from TIG/MIG to Laser Welding

Laser welding is no longer just an innovation for large corporations. It is becoming the standard wherever there is a need to:

speed up production
reduce costs
ensure consistent quality

Laser technology solves these challenges through a combination of higher speed, greater precision, and lower dependence on the human factor.

What Is the Main Difference Between TIG/MIG and Laser Welding?

Working Principle and Impact on Production

Traditional methods (TIG/MIG) generate a wider heat distribution. The material is heated over a larger area, which causes:

significant deformation of the welded part
a larger heat-affected zone
the need for additional finishing

Laser welding works in a completely different way:

it concentrates energy into a small focal point
minimizes heat input
enables faster and more precise welding

This difference is the key reason why laser welding achieves superior results.

Laser vs. TIG/MIG Comparison – Time, Costs, Quality

At first glance, it may seem that the main costs of TIG or MIG welding are only the welder’s time and material consumption. In reality, however, most companies underestimate the so-called hidden costs, which multiply significantly over long-term operation.

These include, for example, the need for additional operations such as grinding, weld repairs, or correcting deformations. Every such step means more time, additional labor, and often extra material – ultimately leading to increased production costs.

Another major factor is production downtime – if the weld does not meet the required quality standards, the entire process slows down or must be repeated. In serial production, this can result in a significant drop in efficiency.

These “invisible costs” are often what make the difference between a seemingly inexpensive solution and a truly efficient technology.

Overview of the Main Differences

Factor	TIG/MIG	Laser Welding
Speed	Low to medium	High
Deformation	Significant	Minimal
Repairs	Frequent	Minimal
Operator skill requirements	High	Lower
Automation	Limited	High

What Causes the Cost Differences

Time = the biggest savings
Laser welding can reduce welding time by dozens of percent. More importantly, it saves preparation time, post-processing time, and repair time. The result is a significantly faster overall production process.

Labor costs
With TIG/MIG, weld quality heavily depends on the welder’s experience. Laser technology reduces qualification requirements, improves consistency of results, and speeds up training. This has a direct impact on both production costs and manufacturing flexibility.

Material and quality
Laser welding minimizes the need for filler material, reduces scrap rates, and limits grinding requirements. Every eliminated step means lower operating costs.

Gas Savings – An Often Overlooked Factor

TIG/MIG – Argon

Traditional methods such as TIG or MIG/MAG most commonly use argon or argon-based gas mixtures. These gases offer technological advantages, but they also result in higher operating costs.

Typical factors include:

Higher gas consumption
→ in practice, consumption can be 2–4× higher compared to laser welding (depending on the application)
Higher gas costs
→ argon is significantly more expensive than nitrogen (often by tens of percent, and in some cases even more)
Continuous consumption during the process
→ gas is required throughout the entire welding cycle, increasing total costs during longer production runs
These factors accumulate over time and have a real impact on production operating costs.

Laser – Nitrogen

lower operating costs
more efficient usage
suitable for a wide range of applications

In the long term, the difference between argon and nitrogen alone can result in significant financial savings.

Where the Biggest Savings Come From

Savings from laser welding are not limited to a single area – they are achieved through a combination of factors:

Production speed
- more parts produced in the same amount of time
- higher production capacity
Process stability
- fewer errors
- fewer repairs
- higher quality
Lower operating costs
- less labor
- less material consumption
- lower gas consumption
- significantly lower gas costs

These factors compound together and create a significant difference in overall production economics.

Why It’s Impossible to Define One Exact Savings Figure

Every production process is different. The results are influenced by:

type of material
material thickness
batch size
production organization
operator/technician experience.

Savings can range from just a few percent to several dozen percent. That is why the best approach is to calculate savings based on real production data.

We’ll Help You Decide

Every production process has its own specifics, and it is not always easy at first glance to determine how much savings can be achieved by switching to laser welding.

If you are considering an investment in new technology or comparing different manufacturing options, discussing your specific case with an expert can be highly beneficial. In practice, details that are not visible in a general comparison often make the biggest difference – such as the type of production, number of operations, or automation possibilities.

We can help you:

evaluate whether the technology is suitable for your operation

design the optimal solution for your production process

Safety in Laser Welding

Laser technology brings not only higher efficiency, but also specific safety requirements. Modern workstations such as the FANTECH LWS 4.0 Optimal address safety comprehensively:

protection against laser radiation
integrated safety features
controlled working environment
minimization of risks for operators

A properly designed workstation significantly reduces risks while also increasing working comfort.

Why Choose a Solution from FANTECH

When selecting a technology, companies often focus mainly on equipment parameters – power, speed, or price. In reality, however, success depends on something else: how quickly you can actually implement the technology in practice and what level of support you receive during its daily operation.

This is where suppliers differ significantly.

FANTECH does not approach laser welding as merely supplying a machine. The goal is for the technology to start delivering real results as quickly as possible – higher productivity, lower costs, and more stable quality. It is therefore not only about the equipment itself, but about how quickly and efficiently you can integrate it into your specific production process.
