PEMA welding and production automation systems
Flexible panel lines for various production needs
Boiler manufacturing: panel production
Pemamek offers a wide range of boiler panel machines for various needs. Our panel lines enable the high level of flexibility that is needed in batch-type panel manufacturing. The fast changeover time for tools makes the line flexible for different tube and fin bar sizes.
Flexible PEMA panel production makes it possible to have a first-step investment to meet various production expansion needs. PEMA stationary panel welding line with a one-panel welding machine is usually designed for small or medium-scale batch production and can have 2-6 SAW power sources. The typical panel width is up to 2000 mm.

PEMA welding automation for tube and coil processing
Boiler manufacturing: tube fabrication
Pemamek has a wide product range available for tube shops. Complete lines are highly automated and can even be controlled by one operator. The combination of efficient cells and fully integrated conveyor systems creates ultimate productivity with solid and constant quality.
Modern welding techniques include conventional TIG as well as multi-hotwire TIG and plasma hybrid processes. Efficient storage and material handling solutions are a prerequisite for coiled production systems. One line can be equipped with several welding stations depending on the required capacity.
Tube shot blasting
Tube shot blasting with steel grit is a prerequisite for high-quality SAW welding. It reduces welding defects and the need for manual repairs after the panel welding.
Tube end beveling and buffing
The tube end beveling unit includes specific tools designed for each groove type. End buffing unit integrated into the end beveling line.
Cutting to length
Tube length measuring and cutting saw is integrated to the PEMA tube line.
Tube to tube welding and seam grinding
Tube to tube welding with hot wire TIG and seam grinding after the welding process is integrated into the PEMA line. Seam grinding is required for panel welding.
Efficiency and quality guaranteed throughout the production line
Pressure vessel production
PEMA solutions cover all welding and material handling needs during these phases.
Heavy vessel production automation requires rigid roller beds and
large size welding Column & Booms or welding platforms. Efficient material transportation without unnecessary crane activities is ensured with transfer cars. We have everything you need for modern pressure vessel manufacturing.
The semi-narrow gap SAW technique is used on welding exceptionally thick plates, typically 50-150 mm.
A narrow, preformed welding groove reduces the seam volume and decreases the amount of fillet material needed. On the other hand, producing a quality seam is a process that places extraordinary demands on a production facility.
PEMA’s 100- 1200-ton rollerbeds are designed to meet the special needs of semi-narrow gap welding. In semi-narrow gap welding, the vessel must be rotated with extreme precision, with no axial movement, even over the longest period of time. For this reason, PEMA’s large roller beds come with an automatic hydraulic anti-creep function to prevent axial movement.

PEMA Nozzle Welding Station
Pressure vessel manufacturing: nozzle welding
PEMA Nozzle welding station for pressure vessels automates the nozzle welding process. The station is an optimal solution for heavy-duty workpieces.
Thanks to its hi-tech features, the system allows the automatic creation of robotic welding programs, based on laser-scanned groove geometry.
PEMA Nozzle welding station is an optimal solution for heavy-duty workpieces. The solution allows the automatic creation of robotic welding programs, based on laser-scanned groove geometry. PEMA Nozzle welding station has a quick ramp-up period.
Automated multi-layer welding results in visibly improved welding quality and reduced defect rate. Furthermore, automation reduces defect rates and saves manual welding hours typically required for a time-consuming and demanding multi-layer welding procedure.
