ALTEC Aluminium-Technik GmbH & Co. KGaA
Efficient lightweight aluminum construction with Fronius welding technology
From scaffolding systems to docking stations: Custom aluminum access solutions
From rolling scaffolds, facade scaffolds, and flat roof fall protection systems to complete docking systems for aviation and numerous special solutions: ALTEC Aluminium-Technik GmbH & Co. KGaA, based in the German town of Mayen, in Rhineland-Palatinate, builds all forms of access solution. In doing so, 95 percent of the company’s business is in lightweight aluminum construction. Thanks to its 35 years of experience in welding aluminum components, the specialist welding company certified to EN 1090-1 and 1090-3 is able to realize even the most complex orders.
- Headquarters: Mayen, Germany
- Founded: 1985
- Employees: < 50
- Production of: aluminum products, scaffolds, fall protection systems, docking systems
- Fronius products in use:TPS 320i
- Process application: CMT, PMC Ripple Drive
The modernization of the system has reduced downtimes to such an extent that they hardly ever occur. The high process stability of the Fronius welding system has therefore thoroughly impressed us.
The challenge at ALTEC
Despite, or perhaps thanks to, the company’s compact size with 50 employees, ALTEC relies on forward-looking production methods: “This includes state-of-the-art CAD workstations, as well as fully automated robotic welding cells and the associated high-tech welding process technology,” explains ALTEC plant manager Siegfried Berenz, a trained master metalworker and international welding specialist (IWS).
As part of the process of advancing automation, in 2018 an aluminum framework part (AlSi1, two millimeters) was to be transferred from manual production to robotic welding. The focus here was on high welding speed in conjunction with maximum process reliability.
A short time later, it was necessary to equip a further existing robot system with new welding technology due to high failure rates. In this case, the unmanipulated welding runs through the vertical-up seam, flat position, and vertical down seam in a single step. One process for all position welds without moving the workpiece was thus a basic requirement. The weld seam appearance also had to be outstanding.
The solution: TPS 320i & CMT process
The Fronius TPS 320i high-tech welding system platform is used on both robotic welding systems. Both power sources are also equipped with the complete CMT hardware. ALTEC also found the ideal solution for the challenge of 2018 in the Fronius CMT welding process. This is because the process can deliver high welding speeds and outstanding process reliability, particularly on light-gage metal sheet. As a result, Fronius was able to establish itself in ALTEC’s production.
During the subsequent retrofit of the existing robot system, the decision was made in favor of the Fronius PMC Ripple Drive pulse welding process variant. The perfect weld properties in out-of-position welding and the large gap-bridging ability, as well as the high degree of process reliability and the TIG-like weld seam appearance were particularly impressive. As a result, failures and component scrap dropped to around zero.
