A Laser Welding Wire Feeder is an auxiliary device used with laser welding machines to supply filler wire during the welding process. The feeder controls wire delivery through the feeding rollers and sends the welding wire to the welding torch at a set speed.
KEMPSON Laser Welding Wire Feeder models use four-drive feeding structures with adjustable wire feeding parameters. The feeder supports welding wire diameters from 0.8 mm to 2.0 mm and feeding speeds from 5-300 cm/min, covering common wire feeding requirements for handheld laser welding applications.
Compared with manual wire feeding, the wire feeder provides continuous wire delivery for thick plate welding, large gap filling, and wide weld seam processing. KEMPSON offers dual wire and triple wire feeder models for different filler wire requirements.
The Four-Drive Dual Wire Feeder uses a four-roll drive structure to feed two welding wires at the same time. It is suitable for thick plate welding, large gap filling, and applications requiring higher filler wire input.
The Four-Drive Triple Wire Feeder uses an upper-and-lower gear-linked four-drive structure to feed three welding wires simultaneously. It is suitable for wide weld bead forming, thick plate welding, and large weld joint filling.
Feeding Tube
Guides the welding wire from the feeder to the welding torch.
Wire Reel Holder
Supports the welding wire spool and keeps wire supply stable.
Control Panel
Adjusts wire feeding speed and operating parameters.
Wire Straightening Unit
Corrects wire bending before the wire enters the torch.
Motor System
Provides power for the wire feeding mechanism.
The Laser Welding Wire Feeder feeds welding wire from the reel to the laser welding torch through the drive roller system. The operator can adjust the wire feeding speed, retract length, and other parameters according to the welding process.
The wire feeding quantity can be selected according to weld seam size and filling requirements. Dual wire and triple wire feeding systems are available for higher filler wire input, and some models can be connected with two welding torches for different welding positions.
Used for carbon steel, stainless steel, and other thick metal materials where additional filler wire is required.
Suitable for welding joints with larger gaps or uneven assembly conditions that need more filler wire input.
Used for welds requiring wider bead width and higher wire feeding capacity.
Applied in excavators, loaders, frames, and other heavy equipment components.
Suitable for steel frames, structural parts, and large welded assemblies.
Used in industrial equipment, machinery parts, and customized metal fabrication.
Applied in pipe joints, tanks, and metal containers requiring stable filler wire feeding.
Used for repairing worn parts, filling gaps, and rebuilding damaged metal surfaces.
The selection of wire feeding type mainly depends on weld seam size, material thickness, wire filling requirement, and welding efficiency. Different wire feeding structures are suitable for different welding conditions.
| Wire Feeding Type | Recommended Material Thickness | Weld Seam Condition | Recommended Application |
| Single strand | 0.5-5 mm | Small weld seams, normal gap filling | Thin plate welding, sheet metal fabrication, repair welding |
| Double strand | 3-12 mm | Medium weld seams, larger filling requirement | Thick plate welding, gap filling, industrial equipment welding |
| Triple strand | 8-20+ mm | Wide weld seams, large filling volume | Heavy structure welding, large components, wide bead forming |
Note: Actual selection depends on material type, laser power, welding speed, wire diameter, and joint design.
The wire feeder can be switched between single-wire and dual-wire modes to meet welding requirements. To learn about the differences between single-wire and dual-wire modes, see the article: Single vs. Dual Wire Feeding for Laser Welding: What’s the Difference?
When using a wire feeder to weld wide gaps and thick plates, the wire feeding speed significantly affects the welding results. For more details, see: Laser Welding Wire Feeding Speed: How to Set the Right Parameters

The selection of a Laser Welding Wire Feeder depends on material thickness, weld seam size, wire diameter, and welding requirements.
Select the feeder according to the welding wire diameter. KEMPSON wire feeders support 0.8-2.0 mm welding wires.
Small weld seams use single wire feeding. Larger weld seams require dual or triple wire feeding for more filler wire input.
Single wire feeders are used for sheet metal and repair welding. Dual and triple wire feeders are used for equipment manufacturing, steel structures, and heavy welding.
Check the power supply, signal connection, and installation requirements before connecting the wire feeder to the laser welding system.
Choose the wire feeder according to material thickness, weld seam size, and filler wire demand. Single wire feeders are suitable for standard welding, while dual and triple wire feeders are used for larger weld seams and higher filling requirements.
Different welding scenarios require different wire feeders depending on the required gap depth. To learn about wire feeder types and how to select the right one, see the article: “What Is a Laser Welding Wire Feeder? Types, Working Principle & Selection Guide”

Laser beam welding is an advanced fusion welding process that uses a focused laser beam as a heat source to melt and join materials. It provides high welding speed, low heat input, small deformation, and precise control, making it widely used in automotive, aerospace, electronics, battery manufacturing, and precision industries.
This article explains whether laser welding is strong, covering weld strength, penetration depth, joint durability, influencing factors, and comparisons with traditional welding methods. It also introduces suitable materials and industrial applications to help users understand if laser welding meets their production requirements.
Laser beam welding uses a high-energy laser beam to generate concentrated heat, melt materials, and create a strong welded joint. This article explains how laser beam welding works, including its working principle, welding mechanisms, key components, advantages, and applications in modern manufacturing.
Laser welding is widely known for its ability to create strong, precise welds with minimal heat input. One of the most common questions is whether filler metal is required during the process. In many applications, laser welding can be performed without filler wire by directly fusing the base materials. However, filler metal becomes important when welding thicker materials, bridging joint gaps, preventing cracking, or joining dissimilar metals. This guide explains how autogenous laser welding works, when filler wire is necessary, whether wobble welding can replace filler metal, and how to choose between wire and powder fillers for different applications.
