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.
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.
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.
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.
The wire is drawn through several dies down to the target diameter, while roundness and surface finish are continuously monitored.
Where required, annealing is applied to soften the wire; phosphate coating prepares the surface for subsequent drawing or forming steps.
The wire is coated with a homogeneous copper layer in specially prepared baths, improving both arc stability and wire feeding performance.
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.
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.
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.
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.
