Fruehauf Enhances Bulk Trailer Manufacturing with Fronius Welding Technology
Fruehauf, a long‑established leader in UK trailer manufacturing, produces more than 500 tipping and bulk trailers each year at its Grantham headquarters, managing the entire process in‑house. To maintain its reputation for strength, reliability and build quality, the company has invested in advanced Fronius welding technology, ensuring consistent, high‑quality welds across both steel and lightweight aluminium trailer structures.
What's your welding challenge?
Every Fruehauf trailer contains numerous welded joints, many located in load‑bearing areas exposed to shock, vibration and torsion.The challenge is intensified when welding aluminium bodies, where controlling heat input is critical to avoid distortion, porosity and defects - particularly when joining thick structural components to thin sidewall panels. Fruehauf needed a solution that could deliver repeatable weld quality, support long weld seams and maintain productivity without compromising structural integrity or appearance.

Solution
Fruehauf
addressed these challenges with Fronius TPS 400i welding systems, using Pulse
welding and intelligent arc control functions to precisely manage heat input
and ensure stable, high‑quality welds in aluminium and steel. The addition of
JobMaster Push‑Pull torches improved wire feed reliability over long body
lengths, while the FlexTrack 45 Pro welding carriage introduced semi‑automation
for longitudinal seams, delivering consistent travel speed, reduced operator
fatigue and significant time savings. Together, these technologies have
improved efficiency, repeatability and weld quality, supporting Fruehauf’s
commitment to reliable, UK‑built trailers.
For the past two years, we've relied on Fronius welding systems because their offerings align perfectly with our core values of commitment to quality and reliability. The TPS 400i and its exceptional welding capabilities, have significantly improved our performance by increasing the speed and flexibility of our manufacturing processes.
