Creating your own fiber laser welder can be a rewarding and cost-effective project. Whether you're a hobbyist, entrepreneur, or professional, assembling a laser welder allows you to customize the equipment to your specific needs. This guide will walk you through the essential components and considerations for building a complete hand-held laser welding machine, including both water-cooling and air-cooling options.
At Sky Fire Laser, we provide a comprehensive Checklist to Make a Whole Laser Welding Machine to guide you through the process.
1. Machine Cover
The machine cover protects the internal components of your laser welder. Depending on your choice of cooling method, the cover's design will vary:
- Water-Cooled Laser Welding Machines: Larger covers to accommodate the chiller.
- Air-Cooled Laser Welding Machines: More compact covers since no chiller is required.

- Air-cooling welder without chiller
2. Chiller (Only Necessary for Water-Cooling Laser Source)
A chiller is crucial for water-cooled laser sources to maintain optimal operating temperatures. Manufacturers now offer integrated chillers with the machine cover for streamlined design and functionality.

3. Laser Source
- Water-Cooling Laser Source: Ideal for higher power output, typically ranging from 1000W to 3000W.
- Air-Cooling Laser Source: Suitable for lighter applications with power ratings between 800W to 1200W.
