If you're already familiar with laser welding, you know it's precise and efficient. But have you considered taking it a step further with laser robot welding?
Laser welding robots combine the accuracy of laser welding with the consistency of robots. Robotic laser welding delivers consistent, high-quality results while freeing up your skilled workers for more critical tasks.
In this article, we'll explore the benefits of incorporating robotic laser welding into your manufacturing process, resulting in cost reduction and improved productivity.
1. Repeatability of welds
One of the standout benefits of robotic laser welding is its ability to deliver consistent, high-quality welds every time. The precision of laser technology ensures that each weld is identical to the last, reducing the risk of errors and inconsistencies.
2. Increased welding speed
Robotic laser welding can drastically increase your production speed. Traditional methods rely heavily on the welder's skill and pace. Laser cobots work quickly and are very accurate. This capability allows you to complete jobs faster without sacrificing quality.
3. Reduction in labor costs
With robotic laser welding, you can reduce your reliance on highly skilled labor, which is becoming more scarce and expensive. Cobots require less human intervention and supervision, which can lead to significant savings on labor costs over time.
4. Decrease in material waste and rework
The precision of robotic laser welding means fewer mistakes and less material waste. High-quality, consistent welds reduce the need for rework, saving both time and resources. This efficiency lowers costs and contributes to a more streamlined production process.
5. Improved safety
Welding can be a hazardous job, exposing workers to intense heat, fumes, and UV radiation. Robotic laser welding minimizes these risks by taking humans out of the most dangerous parts of the process. Cobots can handle the tough, hazardous work, allowing your team to focus on other tasks.
Choosing the right laser welder technology can impact the quality and efficiency of your welding process. Here's a brief overview of the main types of laser welders used in various industries.
' Solid State Lasers: Solid state lasers use a solid medium, typically a crystal or glass, doped with rare earth elements like neodymium or ytterbium. In welding, solid state lasers are ideal for applications requiring precise, high-quality welds, such as in the aerospace and automotive industries. They are excellent for welding thin materials and delicate components.
' Direct-Diode Lasers: Direct-diode lasers generate laser light directly from semiconductor diodes. They are known for their efficiency and compact size. While they typically have lower power outputs compared to other laser types, they are well-suited for welding thin materials and performing spot welding.
' Fiber Lasers: Fiber lasers use an optical fiber as the medium, doped with rare earth elements like erbium, ytterbium, or neodymium. Fiber lasers are used in welding because they can handle a variety of materials, including stainless steel, aluminum, and copper. They are particularly valued for their ability to weld at high speeds and their adaptability to automated processes.
' Gas Lasers: Gas lasers, such as CO2 lasers, use a gas mixture as the medium. These lasers are known for their high power and ability to cut and weld thick materials. CO2 lasers are commonly used in industries that require deep penetration welding, such as shipbuilding, heavy equipment manufacturing, and construction.
CO2 and fiber lasers are the most commonly used types for welding, but fiber lasers stand out for their remarkable efficiency.
Fiber lasers are 5 to 10 times more efficient in energy conversion compared to traditional CO2 lasers. This efficiency translates to much lower operating costs.
The Laser Welding Cobot System and Handheld Laser welder from Cobot Systems incorporates IPG fiber lasers as its power source.
IPG fiber lasers are compact and energy-efficient, and operate reliably in harsh industrial environments. They require minimal maintenance and offer flexible beam delivery for easy production integration.
With wall plug efficiencies exceeding 45%, these lasers provide maximum productivity and the fastest return on investment, making them the industry standard for a wide range of materials processing applications.
Traditional robotic welding systems have been the go-to for automating welding processes in large-scale manufacturing.
These systems excel in high-volume, repetitive tasks, offering speed and precision that manual welding can't match. However, they are expensive and come with some pretty big challenges.
One of the main drawbacks of conventional robotic welding systems is their lack of flexibility. They are typically designed for specific tasks and require extensive reprogramming to adapt to new jobs.
This complexity can lead to longer setup times and increased costs, making them less ideal for small-batch or custom production runs.
Collaborative robots, or cobots, are designed to work alongside humans. They are flexible and easy to use and don't require any programming knowledge.
They are adaptable and can perform a wide range of tasks without extensive reprogramming. This makes them ideal for environments where production needs can change frequently.
Cobots are designed to be safe around human workers, reducing the need for extensive safety barriers, which allows for more efficient use of space. These factors make them a cost-effective solution for many manufacturing applications.

With so many ways to join materials, here are our top 10 reasons to use laser welding.
Laser welding can be used to join a variety of metals, including stainless steel, nickel, titanium, Inconel, and molybdenum.
Notably, laser welding can also be performed with reflective materials, such as copper and aluminum. Joining reflective and dissimilar metals can be difficult or impossible to perform with other welding methods, but laser welding makes it significantly easier.

We use lasers to weld medical device components, including microfluidics chips and surgical equipment. If it's small or needs to be welded in a hard-to-reach place, laser welding is the go-forward method.
In addition to creating microscopic welds, lasers are capable of welding thicker materials and creating structural welds that are 1/2' deep.
If you totally love how your laser welded components turned out, we have good news for you: those results are repeatable. We can do it again, and again, the exact same way. This is because laser welding is'*drumroll'*
For each job, our laser welding systems' parameters are customized. With this noncontact process, we can easily control the size of the laser beam and, therefore, the size of the heat affected zone (more on that later!).
Laser welding can perform in minutes what TIG welding could perform in hours. The travel rate of the laser can be between hundreds and thousands of inches per minute.
Laser welding transmits heat in small, controlled areas. Other processes, like MIG welding, have greater heat inputs, which causes more residual stress on the component. Controlling the heat affected zone with laser welding keeps more of the metallurgical structure intact. The result is a higher quality weld that require less finishing and heat treating.
Laser welding's-controlled heat affected zone also makes it possible for us to weld the exterior of a device without harming thermal-sensitive internal components.
Laser welding can be performed in an open-air environment or in a glovebox. This opens up the possibility for working on larger components if you have a capable laser for the job.
Robots have been welding since , and have been used more and more ever since. The road to innovating with this technology is paved and getting smarter all the time.
Out of all 10 reasons to use laser welding, this is one of the best! You can achieve high quality results without compromising your budget. Laser welding is fast, controllable, and repeatable, making this method highly productive and efficient.
Although laser welding equipment is expensive, working with a contract manufacturer like Joining Technologies can allow you to enjoy the benefits of laser welding for a lower cost. It eliminates the need to secure the floor space, talent, and equipment required for an in-house operation.
