Selecting the right laser welding machine requires more than choosing the highest available laser power. Material type, thickness, welding requirements, operating conditions, and production needs all influence which configuration is appropriate. For manufacturers and fabricators, matching the machine to the materials being processed can help support consistent weld quality and efficient operation.
ACCURL’s SMART HLW handheld laser welding and cleaning systems are available in multiple power configurations, including 1000W, 1500W, 2000W, and 3000W. The systems are designed for welding a range of materials and thicknesses while providing high-speed welding, low heat input, and integrated pre- and post-weld cleaning capabilities.
Why Metal Thickness Matters When Choosing a Laser Welding Machine
Metal thickness is one of the primary considerations when selecting a welding system. Different thicknesses require different levels of laser power and process settings to achieve the desired welding results.
ACCURL’s SMART HLW systems are designed to work across a range of thick, thin, reflective, and dissimilar materials. The focused fiber laser beam provides high-speed welding with low heat input and a small heat-affected zone. This can help minimise distortion and deformation during the welding process.
Rather than selecting equipment based only on maximum power, buyers should consider the thicknesses they process most frequently and compare those requirements with the manufacturer’s published parameters.
Match Laser Welding Power to Metal Thickness
1000W Laser Welding for Thin Materials
The SMART HLW-1000 provides a 1000W configuration for applications involving thinner materials. According to ACCURL’s published parameters, it can weld stainless steel, galvanized steel, mild steel, and 3 and 5 series aluminum up to 2.5 mm. For nickel alloys, the published capacity is up to 1.5 mm.
For manufacturers whose regular applications fall within these ranges, a 1000W configuration can provide an appropriate starting point without selecting a higher-power system than the application requires.
1500W Laser Welding for Medium Thicknesses
The SMART HLW-1500 increases the published welding range for several common metals. ACCURL lists stainless steel, galvanized steel, mild steel, and 3 and 5 series aluminum up to 4 mm for this configuration. Nickel alloys are also listed up to 4 mm.
This makes the 1500W option relevant for applications where production involves medium material thicknesses and requires more capacity than the 1000W configuration provides.
2000W Laser Welding for Higher Thickness Requirements
For applications involving greater thicknesses, the SMART HLW-2000 provides additional laser welding power. ACCURL lists stainless steel, galvanized steel, mild steel, and 3 and 5 series aluminum up to 6.35 mm. Nickel alloys are listed up to 5 mm.
If a production environment regularly handles these thicknesses, the 2000W configuration may be worth considering. Buyers should still evaluate their specific materials and application requirements before choosing a final machine configuration.
When to Consider Higher Fiber Laser Welding Power
ACCURL’s laser welding and cleaning systems are available with power options up to 3000W. The website notes that laser welding power can be adjusted using intuitive controls to help operators select settings for different materials and thicknesses.
The highest available power is not automatically the right choice for every application. Instead, manufacturers should consider their typical material range, maximum thickness, production requirements, and desired workflow before selecting the final configuration. ACCURL notes that specific parameters can vary according to the final configuration and model, with fixed parameters provided in the quotation.
Compare Laser Welding Capabilities by Metal Type
Laser Welding for Stainless Steel
Stainless steel is among the materials listed for ACCURL’s SMART HLW systems. The published welding range increases from up to 2.5 mm with the 1000W configuration to up to 4 mm with 1500W and up to 6.35 mm with 2000W.
This makes material thickness an important factor when choosing the appropriate fiber laser welding power for stainless steel applications.
Laser Welding for Mild Steel
ACCURL also lists mild steel across the 1000W, 1500W, and 2000W configurations. The published capacities are up to 2.5 mm, 4 mm, and 6.35 mm respectively.
Manufacturers can use their regular mild steel thickness range as one of the criteria for narrowing down the appropriate machine configuration.
Laser Welding for Galvanized Steel
Galvanized steel is another material supported by the SMART HLW systems. ACCURL lists the same published thickness ranges across the three configurations: up to 2.5 mm for 1000W, 4 mm for 1500W, and 6.35 mm for 2000W.
When selecting equipment, buyers should therefore consider galvanized steel thickness alongside the other materials processed in their facility.
Laser Welding for Aluminum
ACCURL specifies compatibility with 3 and 5 series aluminum. The published ranges are up to 2.5 mm for the SMART HLW-1000, 4 mm for the SMART HLW-1500, and 6.35 mm for the SMART HLW-2000.
Because aluminum applications can vary by material and thickness, buyers should identify the specific aluminum grades and thicknesses they need to weld when discussing their machine requirements.
Laser Welding for Nickel Alloys
Nickel alloys have different published thickness capabilities compared with several of the other materials listed by ACCURL. The SMART HLW-1000 is listed up to 1.5 mm, while the 1500W configuration is listed up to 4 mm and the 2000W configuration up to 5 mm.
For nickel alloy applications, identifying the specific material and required thickness is particularly important before selecting the machine configuration.
Is Handheld Laser Welding Right for Your Application?
ACCURL’s SMART HLW is a handheld laser welding and cleaning system designed for flexibility and ease of operation. The system features a lightweight welding head weighing approximately 760 g and an ergonomic design intended to provide greater operator control and comfort.
The welding head can accommodate different nozzle angles for various products and welding requirements. Operators can also switch between presets for different material thickness combinations.
ACCURL states that the system supports high-speed welding with a wide welding seam, low porosity, and melting pool protection. The system also supports wobble welding up to 5 mm.
How Laser Welding Presets Help With Different Thicknesses
When working with multiple materials and thicknesses, setup time can become an important production consideration. ACCURL’s SMART HLW systems include built-in factory presets for materials and thicknesses, with up to 74 stored preset and user-defined process parameters.
These laser welding presets allow operators to quickly switch between process settings for different material thickness combinations. This can simplify operation, particularly for facilities that regularly change between applications.
The intuitive controls are also designed to make the system easier to learn and operate, helping operators select appropriate settings without requiring a complicated setup process.
