Key Consumables for Handheld Laser Welding Machines

Handheld laser welding machines have gained prominence in various industries due to their precision and efficiency. These machines are essential tools for intricate welding tasks, offering the capability to fuse metals with accuracy and reliability.

The use of filler wires for laser welding, depending on the client's application, can generate the following benefits:

• Improve the quality of the joints

• In the case of welding stronger materials, the welded joints are much more resistant and qualitative.

• Cracks will be avoided in the case of certain materials

In the case of laser welding with additional materials (wires) - the speed of the welding wires must be properly configured, depending on the thickness of the welded material and the speed at which the person wants to work. It will also depend on the type of welding you will be doing.

1. Wire Feed System Machines:

   Handheld laser welding machines equipped with wire feed systems require the following consumables:

   a. Welding Wire: Typically made of aluminum, welding wires come in various diameters such as 0.3mm and 0.6mm. A single large coil of welding wire can last for several months, making it a cost-effective consumable for extended use.

   b. Copper Nozzles: Copper nozzles are positioned at the welding point and are integral to the welding process. Despite being consumed during the welding process, proper usage can extend the lifespan of a single copper nozzle to around 5-8 welding operations.

2. Cooling Water:

   While not directly consumable, cooling water plays a vital role in extending the lifespan of the handheld laser welding machine. Using distilled or purified water with minimal impurities is recommended. This practice reduces the impact of impurities on the laser's longevity and overall performance.

Types of alloys for laser welding

The laser welding method is used in fields such as the automotive, aeronautical, medical, jewelry, etc. industries, and offers the deposition of a thin layer of addition without altering the properties of the base material. At the same time, it does not cause deformations of the base part, limiting the temperature induced in the material.
