Trusted Wire Production for Strong Welds

We produce our welding wires end-to-end in our own facilities. After surface cleaning, multi-stage drawing, annealing–phosphate coating and copper coating, the wires are taken to winding with final quality checks. With a range of diameters and reel / drum packaging options, our wires are supplied ready for both robotic and manual welding lines.

Production Steps

From raw material preparation to final winding, welding wires pass through consecutive processes. The key steps below are designed to deliver high conductivity, stable arc behaviour and consistent feeding.

01

Surface Cleaning

Mill scale, grease and oxides on the wire rod surface are removed in chemical baths, reducing the risk of porosity and spatter in the weld pool.

02

Multi-Stage Drawing

The wire is drawn through several dies down to the target diameter, while roundness and surface finish are continuously monitored.

03

Annealing & Phosphate

Where required, annealing is applied to soften the wire; phosphate coating prepares the surface for subsequent drawing or forming steps.

04

Copper Coating

The wire is coated with a homogeneous copper layer in specially prepared baths, improving both arc stability and wire feeding performance.

Starting point

Raw Material Preparation & Drawing

Welding wire production starts with steel wire rod that has passed incoming quality control. Surfaces are cleaned in dedicated chemical baths and, where necessary, shot-blasted and phosphate-coated to make them suitable for drawing. On our multi-stage drawing lines, the wire is reduced to the requested diameter and transferred to the next process with smooth surface and tight tolerances.

Copper Coating Line

After final drawing, the wire is passed through degreasing, rinsing and activation baths on a continuous line before entering the copper coating section. Controlled bath chemistry and line speed allow us to achieve the required copper thickness with a uniform layer.

This layer enhances electrical conductivity and arc stability while reducing wear on drive rolls and contact tips during feeding.

  • Homogeneous and controlled copper thickness
  • Improved conductivity and stable arc formation
  • Reduced wear on feeding rollers and contact tips

Quality Control & Testing

Wires that pass all mandatory mechanical, dimensional and surface tests are approved for winding and shipment. Each reel is labelled with a batch number for full traceability. Tensile strength, elongation, hardness, coating thickness and adhesion, as well as feeding tests, are regularly performed to confirm compatibility with customers’ welding equipment.

  • Tensile strength, elongation and hardness tests
  • Coating thickness and adhesion controls
  • Feeding tests for welding machine compatibility
  • Checks on surface cleanliness and copper layer continuity
Final step

Winding & Packaging

Approved wires are wound onto reels or drums and labelled according to their end use. From 15 kg reels up to 250–300 kg drums, we offer packaging options suitable for both manual and robotic welding lines. Winding pattern, layering and brake settings are adjusted to support smooth feeding during operation.
