THIN-WALL TANK WELDING AT APLwith the next-generation PEMA WeldControl X
To further strengthen its capabilities, APL once again turned to Pemamek — this time continuing the long standing partnership with an investment in a PEMA column & boom system. Alongside the new equipment, APL also became a pilot user of the next-generation WeldControl X software.
Continuing a trusted partnership
APL’s journey with Pemamek began more than a decade ago. Over the years, the company has steadily expanded its automation capacity with several PEMA solutions, including column & boom systems, assembly lines, rollerbeds, and positioners. Each investment has delivered measurable improvements in quality, throughput, and operator ergonomics.
“The use of PEMA equipment at APL Production AS has delivered positive results, expanding welding capabilities and ensuring a consistent increase in labor productivity,” says APL’s welding engineer.
The newest addition, installed in 2024 — a PEMA 6×5 HD C&B station with SAW and MIG/MAG welding capabilities, along with A25S roller beds — marks another milestone in the partnership. Beyond its standard features, this system was among the first in the world to run the next-generation
WeldControl X welding software.
From proven performance to next-generation control
Before the latest installation, APL was already operating two PEMA C&B systems equipped with WeldControl 100. These systems delivered robust performance and significantly improved production efficiency. With the move to WeldControl X, however, a new chapter begins.
Designed for intuitive operation, enhanced data management, and advanced process control, PEMA WeldControl X offers operators more real-time insight into welding parameters and project status. The software’s streamlined interface helps shorten training times while enabling quick adjustments during production.
“The new WeldControl X software features an improved interface that enables operators to manage the welding process at a high level. Welding engineers were able to develop optimal parameters with minimal heat input and maintain control throughout the process. This reduced welding deformations and made it possible to weld materials from 5 mm thickness — especially important when working with high-alloy grades such as 904L, 253MA, 254SMO, Alloy 825, Duplex, and Super Duplex,” says APL’s welding engineer operating the new system.
Meeting the challenge of complex fabrication
APL’s fabrication involves thin-walled, large-diameter workpieces that demand precise multi-process welding. With the new C&B 6×5 HD and its expanded reach, operators can handle bigger structures without repositioning, reducing setup time and increasing arc-on time.
The combination of SAW and MIG/MAG processes in a single station ensures flexibility: submerged arc welding for long, consistent seams, and MIG/MAG for areas requiring more intricate work. Together with precision positioning equipment, the system helps APL maintain high weld quality while meeting tight delivery schedules.
Deciding factors: technology, training, and trust
Operator-friendliness, training support, and service reliability have all played a role in successful installation, ramp-up, and ongoing production. The chance to be a pilot site for WeldControl X was seen as an opportunity to influence future developments while gaining early access to the latest features.
“Our well-established contact with PEMA’s technical specialists has made it possible to promptly implement our engineers’ suggestions and quickly address any issues that have arisen during the process,” says APL’s welding engineer.
