Manhart How to choose the appropriate handheld laser power?

When selecting the appropriate handheld laser power, multiple factors should be comprehensively considered to ensure that welding requirements can be met and the best results can be achieved. Here are some key steps and considerations:
1. * * Clarify welding requirements * *:
-* * Material type and thickness * *: Different materials and thicknesses have different absorption rates for lasers. Non ferrous metals (such as copper and aluminum) typically have lower laser absorption rates than ferrous metals (such as steel and iron). Welding non-ferrous metals may require higher power laser welding machines.
-Welding speed: High speed welding requires higher power laser welding machines to meet production needs.
-* * Budget Limit * *: Laser welding machines with higher power usually have higher prices, so budget is an important consideration when selecting power.
2. * * Choose power based on material thickness * *:
-* * Thin plate material (less than 2mm) * *: Handheld laser welding machines with a power range of 500 watts to 1000 watts are usually sufficient.
-* * Medium thickness material (2mm to 6mm) * *: A laser welding machine with a power output of 1000 to 2000 watts may be required.
-* * Thick material (over 6mm) * *: A high-power laser welding machine of 2000 watts or more may be required.
3. * * Consider future application needs * *:
-If it is expected that there will be a demand for thicker materials or higher production efficiency in the future, it may be more economical to invest in slightly higher power equipment at the beginning.
4. * * Evaluate device parameters * *:
-Understand the power range of handheld laser welding machines, usually between 100W and 3000W.
-Pay attention to the beam quality of the equipment. Equipment with good beam quality has higher focusing and cutting ability, which can achieve efficient and high-quality welding.
5. * * Brand and Model Comparison * *:
-Choosing a well-known brand of handheld laser welding machine ensures better quality and after-sales service.
-Compare the prices, performance, and features of different brands and models before purchasing, and choose the product with the highest cost-effectiveness.
6. * * Consider other features * *:
-Choose a handheld laser welding machine with functions such as automatic focusing and manual power adjustment as needed, which can improve the convenience of operation and welding flexibility.
7. * * Communicate with suppliers * *:
-Suggest detailed communication with the equipment supplier to understand the specific performance, scope of application, after-sales service, and other information of the equipment.
-If possible, conduct on-site testing to ensure that the selected laser welding machine meets current needs and has certain future development potential.
Summary: Choosing the appropriate handheld laser power is a comprehensive consideration process that requires balancing current and potential future needs, while considering cost-effectiveness. By clarifying welding requirements, selecting power based on material thickness, considering future application needs, evaluating equipment parameters, comparing brands and models, and communicating with suppliers, one can find the most suitable handheld laser welding machine for oneself.
