Which Wire to Use for Laser Welding?

Laser welding is a precise technology that allows clean and durable metal joints. The choice of welding wire plays a crucial role in the strength, appearance, and mechanical properties of the weld.

The Role of Wire in Laser Welding

During laser welding, the laser beam melts both the base material and the added wire, creating a seamless joint. Since the process uses less heat, it minimizes distortion. The welding wire must have high chemical purity, consistent composition, and precise diameter for stable feeding and melting.

How to Choose Laser Welding Wire?

• Stainless steel wire – for corrosion-resistant and stainless steel parts,
• Aluminum wire – used for welding aluminum and its alloys,
• Copper or bronze wire – for non-ferrous metals and mold repair,
• Alloyed wire – enhances mechanical strength and resistance.

What to Consider When Selecting Wire?

• Wire diameter – matched to the laser power and material thickness,
• Surface purity – no oxidation or dirt ensures consistent results,
• Chemical compatibility – the alloy must match the base metal,
• Melting characteristics – depending on the laser type used.
