This welding process is quickly charting new territory. However, manufacturers currently lack AWS specifications for handheld laser beam welding. Guidance for handheld laser welding in the aerospace industry is being drafted by the AWS D17 Committee on Welding in the Aircraft and Aerospace Industry from auto-mated laser welding specifications, insights, and best practices from early-adopting manufacturers. These manufacturers are reporting several benefits of handheld laser welding: ease of use for the workforce not formally trained in traditional welding processes, cost and time savings, and reduced distortion. Given the new technology, safety is also a top priority. 

Labor Market Benefits for Aerospace Manufacturers 

Aerospace manufacturers and defense contractors require welding operators to meet strict production schedules. The ongoing labor shortage continues to affect the welding industry, with an estimated 82,500 welders needed annually through (weldingworkforcedata.com). Manufacturers attempt to fill the gaps by scouting talent at trade schools, utilizing workforce companies to attract welders, and supplementing skilled laborers with cobots and automation.  

Handheld laser welding can open the labor market for manufacturers because it reduces the learning curve for beginning welders. Technology makes this new technique less complicated than traditional welding processes, where multiple factors (contact tip to work distance, angles, travel speed, and filler metal feed) must be met for a quality weld. Handheld laser welding offers a simpler approach, with drag tip design and wire feeding that controls the travel speed. Beginner welders can get up and running in hours vs. weeks. This easier-to-use, efficient technology is ideal for the aerospace manufacturing sector. 

Cost and Time Savings for Aerospace Manufacturers 

Considering high inflation, rising capital costs, and steep competition faced by the aerospace industry, equipment and labor costs are always a concern for these manufacturers. The expense of automated systems can be a barrier to small and midsize businesses. However, handheld laser welding units can be purchased for a fraction of the cost of traditional automated laser systems and don’t require the added expense of having programmers and engineers on staff. Due to the ease of use of handheld laser welding units, manufacturers can expand their business capabilities by employing beginner welders so that highly skilled welding talent can be retained for more-complicated applications.  

Handheld laser technology also drastically reduces cleanup time for aerospace manufacturers. The precision of laser welding, along with built-in pre- and postwelding cleaning capabilities in some welding machines, can dramatically decrease production time. For example, a manufacturer who introduced the technology into its operation said its postwelding cleanup and straightening dropped from two days to two hours. Laser welding is also inherently more efficient and productive, with times the power density of traditional arc welding, which leads to higher travel speeds. 

By virtue of precision, handheld laser welding can efficiently replace the traditional labor-intensive intermittent welding process. One manufacturer that had previously measured and marked intermittent welds achieved a 50% reduction in weld prep time using handheld laser welding, along with the ability to weld the entire piece and eliminate setup time. The manufacturer anticipated cutting the entire operational timeline in half by replacing intermittent welding with handheld laser welding.  

Reduced Distortion in Aerospace Manufacturing 

The thin, lightweight materials commonly used in the aerospace industry are susceptible to distortion if not welded correctly. Because laser welding typically results in less heat input than arc welding, part distortion is minimized. Here are a few examples of how handheld laser welding reduced distortion for aerospace manufacturers and defense contractors, ultimately increasing their productivity.  

 A private space company switched from gas tungsten arc welding to handheld laser welding on its spacecrafts, allowing it to use thinner and less weld material. This allowed for more payloads (e.g., satellites) to be sent into space, increasing profitability. 

 A defense contractor whose parts were distorting and shrinking from arc welding had to hand-drill hundreds of holes to meet tolerance for the job. By substituting handheld laser welding, the manufacturer was able to automate the drilling of the holes due to lack of distortion; it was also quite surprising that a beginner welder could complete the task. 

 A manufacturer that used arc welding was able to eliminate burn-through and greatly reduce the use of adhesives, which pose fume and cleanup hazards, by implementing handheld laser welding.  

Safety in Aerospace Handheld Laser Welding  

Safety is an integral component of welding, regardless of the specific process used. For handheld laser welding, there are notable safety considerations to be aware of before implementing this process. Handheld laser welding units are best when equipped with several safety functions that protect operators and passersby. Some units come equipped with built-in safety features, including the following:  

 Back-reflection sensing, which shuts down the machine if the laser is reflecting back into the lens, protecting the operator and the system. 

 Plasma detection, which stops the unit if it is pointed away from the weld piece and doesn’t sense the plasma created by laser welding. 

 A continuity sense clamp, which requires the torch nozzle and the workpiece to be connected for the unit to activate. In some units, this safety measure also functions during the cleaning process. 

The ANSI standard for Class 4 welding lasers requires a staff member at the purchasing company to be certified as a laser safety officer (LSO). The LSO is responsible for ensuring the laser is operated/demonstrated safely by trained personnel and that the environment surrounding the laser welding cell or laser-controlled area is safe for people nearby when the laser is in operation. Handheld laser welding operators must also wear specific laser safety goggles and an appropriate laser-safe helmet that has an additional filter for infrared wavelengths, as determined by the LSO.  

In addition, the AWS Safety and Health Committee and the SH4 Subcommittee on Labeling and Safe Practices prepared a new Safety and Health Fact Sheet, No. 46, on Handheld Laser Welding Safety. This is avail-able as a free download at aws.org/standards-and-publications/free-resources. 

AWS Specifications 

The AWS D17 specifications are industry consensus standards and, therefore, are not required to be used. However, utilizing the standard reduces the liability for manufacturers, which has driven its widespread adoption. In light of significant interest from the North American welding industry, work within D17.1/D17.1M:, Specification for Fusion Welding for Aerospace Applications, to account for the use of handheld laser welding units has already begun. Per the AWS process, the task group is drafting recommendations for the specification. The committee will take into account various sources of information, including the existing automated laser welding criteria as well as data from manufacturers who are already testing and using the handheld laser technology in their operations. The process of developing and vetting the criteria for the standard is expected to last several years.  

Though there’s no current AWS specification for handheld laser welding, AWS B2.1/B2.1M:, Specification for Welding Procedure and Performance Qualification, may be supplemented as a generic way to self-qualify a weld. In that case, an engineer decides which specification to test to. Most codes say the engineering authority may deviate from this and the engineering authority must sign off on it. 

The Path Forward 

As aerospace manufacturers continue to seek precision welding processes, handheld laser welding stands to become more widely used. Labor, cost and time savings, and reduced distortion are major opportunities available with handheld laser welding that can reduce the industry’s current labor gap, allowing inexperienced welders to start producing quickly so skilled welders can complete more-complicated tasks. When including operators actively in handheld laser welding, it’s important to consider more-extensive safety precautions to keep them safe. As the aerospace specification for handheld laser welding is developed by the AWS D17 Committee, all these considerations will be taken into account and may be reflected in the resulting specification.

How does a Handheld Laser Welder Work?

Handheld Laser Welder works by utilizing concentrated laser beams to melt and fuse metal surfaces with exceptional precision. The core technology behind handheld laser welding  is based on the emission of highly focused light, or photons, that are amplified and directed through a laser source. The beam is delivered to the metal surface through a flexible, handheld device, allowing the operator to control the welding process manually. The laser generates intense heat at the exact point of contact, causing the metal to melt and form a seamless joint upon cooling.

The handheld laser welder machine  operates with a fiber optic system that transmits the laser beam from its power source to the handheld tool. Inside the tool, lenses and mirrors focus the beam to the desired spot size, ensuring precision during welding. The operator adjusts the laser’s intensity, pulse duration, and frequency to match the specific material and thickness being welded. The level of control makes handheld laser welders effective for applications requiring fine, intricate welds on metals such as steel, aluminum, and titanium.

A key feature of handheld laser welding  is its ability to weld without direct contact between the tool and the workpiece. The non-contact nature minimizes wear and tear on the equipment and reduces the risk of contamination or damage to the materials being joined. It limits the heat-affected zone because the laser beam is so focused, minimizing warping or distortion in the surrounding metal, a common issue in traditional welding methods.

What are the Components of a Handheld Laser Welder?

The Components of a Handheld Laser Welder are listed below.

• Laser Source/Generator: The laser source/generator is the heart of the handheld laser welding machine. It produces a concentrated beam of light to heat and melt the metal surfaces for welding. The laser source is essential, as the machine does not operate without it. The type and power of the laser determine the weld’s quality and the materials it handles. No welding occurs without the laser source, making it a fundamental component.
• Handheld Welding Gun: The handheld welding gun is the operator’s tool to direct the laser beam to the workpiece. The component provides precision and flexibility, allowing for manual welding process control. The gun is crucial because it enables the operator to manipulate the laser in hard-to-reach areas accurately. The handheld laser welder is only functional with the gun, as it is the interface between the operator and the welding process.

The laser generator and other components overheat without adequate cooling, leading to damage or system failure. The cooling system is vital for maintaining operational efficiency and ensuring the machine’s longevity. The absence of the component severely limits the welder’s performance during heavy-duty tasks.
• Control Panel: The control panel allows the operator to adjust and monitor the laser’s settings, such as intensity, pulse duration, and welding speed. It controls the welding process, ensuring the machine is tailored to specific applications and materials. It is far less precise and user-friendly when handheld laser welding occurs without a control panel, limiting the operator’s ability to adjust parameters for different tasks.
• Laser Beam Delivery System: The laser beam delivery system transmits the laser beam from the generator to the handheld gun. It involves fiber optics or mirrors to direct the beam with minimal energy loss. The component is crucial because it ensures the laser reaches the workpiece efficiently and without distortion. The laser generated is not usable at the point of contact without the system, rendering the machine ineffective.
• Power Supply: The power supply provides the necessary energy to operate the handheld laser welder machine. It ensures the laser source, cooling system, and other electronic components have a stable power supply. The machine only works with the power supply needed to generate the laser and maintain all the other systems.
• Protective Shielding: Protective shielding protects the operator from harmful radiation, sparks, and heat generated during handheld laser welding. It plays a vital role in safety, ensuring the operator is not exposed to dangerous laser light or flying debris. It poses significant risks to the user while the machine technically operates without protective shielding, making it a component essential for safe operation.
• Safety Systems: A handheld laser welder head safety system includes emergency stop buttons, interlocks, and sensors that detect unsafe operating conditions. These systems ensure the machine operates within safe parameters and automatically shuts down in case of a malfunction. The importance of these systems is overstated, as they prevent accidents and injuries. Operating the welder without these safeguards is extremely dangerous.
• Gas Delivery System (optional): The gas delivery system supplies shielding gas, such as argon, to the weld site to protect the molten metal from oxidation and contamination. The system is not necessary, depending on the material and application, but for certain metals, it significantly improves the weld quality. The welder functions without the system, but the weld is more prone to imperfections if shielding gas is required for the specific job.
• Workpiece Fixture (optional): The workpiece fixture holds the materials in place during welding, ensuring stability and alignment. It is useful when precision and consistency are critical while not essential for all applications. A handheld laser welder operates without a fixture, but the quality and accuracy of the weld suffer without it for complex or delicate tasks.

What are the Classifications for a Handheld Laser Welder?

The Classifications for a Handheld Laser Welder are listed below.

• Power: Handheld laser welders are classified into three categories: low-power, medium-power, and high-power. Low-power welders (100W–500W), which are suitable for light-duty tasks, thin materials, and precision welding. Medium-Power Welders (500W–W) are ideal for moderate applications such as automotive repairs and general fabrication, and High-Power Welders (W–W+) are designed for heavy-duty industrial use where thicker materials require high-intensity welding.
• Cooling System: Handheld laser welders are either Air-Cooled or Water-Cooled. Air-cooled welders use air or fans to dissipate heat, making them lighter and more portable, ideal for lower-power tasks or intermittent use. Water-cooled welders use a water circulation system for cooling, offering higher efficiency and preventing overheating during extended high-power operations.
