Welding wire leaves very little room for error. If the diameter varies, the copper coating is patchy, or the wire is badly layered on the spool, the welder will notice it as feeding problems at the torch. Robotic welding cells are even less forgiving. A welding wire is only as good as the welding wire machinery that drew, coated and wound it.
Lämneå Bruk has built welding wire machinery for every one of those steps for decades. We were founded in 1727 as an ironworks in Ljusfallshammar, Sweden, and have built wire machinery since 1823. Today the Hagstedt family runs the company in its ninth generation, and our machines run in 98 countries. As a wire machinery manufacturer, we design, develop and build every part in-house, from single machines to complete welding wire lines and entire new plants.
We divide welding wire production into four stages, and we build machines for each one:
We also supply dedicated lines for submerged arc welding (SAW) wire and flux-cored wire lines. Because every stage comes from the same manufacturer, the machines are built to work together into complete welding wire solutions, and you have a single contact person for the whole line.
Drawing quality depends on how well the rod is prepared. Our vertical payoff takes rod from 5.5 to 12 mm and coils of up to 5 tons (2 × 2.5 t). The integrated snarl protection keeps the line running steadily.
Our reversed bending descalers remove mill scale mechanically at up to 4 m/s. A sandpaper machine then cleans the surface further. Finally, the cleaning and lubricant coating machine removes any remaining scale with hot water and applies the lubricant carrier that dry drawing needs. See our rod preparation equipment.
Our Wire Drawing Loop Line is configured to match your product range, with:
Operators can choose which blocks to use for each product, so you can change the size range without rebuilding the line. We supply control systems from Siemens, Mitsubishi or Allen-Bradley to match your plant standard.

How welding wire is wound matters as much as the wire itself. Precise layer winding helps the wire pay off smoothly in the feeder, without kinks or tangles. Our rewinding lines cover every common welding wire package:
We have built No Twist Coilers since 1992. Because the wire comes out of the drum free of twist, no extra straightener is required.
Every manual spool change means a stop and a risk of operator error. Our fully automatic applications are designed to take both out of the process. The FA-PLW winders change spools automatically. A palletiser with label applicator can serve up to four FA-PLW 300 or 450 machines, so full spools are stacked and labelled without anyone handling them.
No two wire plants are the same. Wire grades, spool formats, floor space, line speeds and existing equipment all vary. That's why every project starts with your product and production targets, not with a catalogue model. We currently build 123 machine types, and we adapt each one to the line it will join, whether that's a modified inlet height, a different spool formator a complete plant layout.
Custom wire machinery solutions like these come from close work with the people who run the machines every day. That's also where our most innovative wire machinery has started.
As a full-service supplier, we support you from the first layout drawing until long after start-up:
Our wire industry expertise covers welding, stainless and high- and low-carbon wire, and we bring it into every project, whether you are adding one rewinding line or planning a complete new welding wire plant.
Yes. We build machines for every stage, from rod preparation (payoff, descaling, cleaning and lubricant coating) through wire drawing, copper coating and skin pass, to spooling, precision layer winding and palletising. You can buy single machines to expand an existing line, complete production cells, or a full new plant planned from the floor layout up, with one supplier responsible for how the machines work together.
Yes. Our rewinding and coiling machines cover MIG/MAG wire from Ø0.8 to 1.6 mm and SAW wire from Ø2.0 to 4.8 mm, in carbon, stainless and flux-cored versions.
Fully automatic precision layer winders (FA-PLW) change spools automatically, so the line keeps running while full spools are swapped for empty ones. With a palletiser and label applicator, one palletiser can serve up to four FA-PLW 300or 450 machines. Semi-automatic winders (SA-PLW) need an operator for the spool change, but they accept a wider range of spool types, including Ø760 mm spools on the SA-PLW 760.
Wire with residual twist can spiral as it leaves the drum, which disturbs feeding in automated welding cells. Our no twist coilers reverse the pre-twist during coiling, so the wire leaves the drum straight and needs no extra straightener. Drums of up to 2,500 kg can be linked end to end for a non-stop payout from one drum to the next.
Yes. We adapt each machine to the line it will join, for example the inlet wire height, the spool format or the control system. We supply controls from Siemens, Mitsubishi or Allen-Bradley, so new machines can run on the same automation standard as your existing equipment.
Our own technicians handle installation and commissioning at your site. After start-up, they provide remote troubleshooting by phone or online, and come onsite when a problem needs hands-on work. We also supply spare parts for our machines.
If you are planning new welding wire capacity or want to upgrade an existing line, our engineers will look at your requirements and suggest the wire machinery solutions that fit them.
