PEMA welding and production automation for offshore and process industry
Maintaining a competitive edge in the offshore and process industry requires high-quality, automated welding and production solutions
PEMA solutions are developed to safely and efficiently handle heavy steel structures and unconventional alleys used in the production of, for example, pressure vessels and nuclear reactors.
PEMA welding and production automation systems for offshore & process
PRESSURE VESSELS AND TANKS:
Shell Fabrication and Assembly
With PEMA shell fabrication solutions, you can dramatically decrease the welding time during your production
Special functions have been designed to make the work flow even more easily. PEM Assembly and welding station can decrease fit-up and tacking time up to 50%: it is based on the self-aligning rollers, fixed jig unit, and a “growing line” function.
Special functions to increase efficiency
- Multi-arc SAW welding with automated functions
- Conical shell tilting
- Fully auto-adjustable special PU rollers
- Fast rotation from internal to external welding in long
seam welding - Integrated grounding
- Wireless control
- Extremely fast fit-up with assembly line developed
specifically for wind tower assembly
Milling of longitudinal seams

Milling
Milling is crucial for all sectors that have heavy welding in their production
It increases production efficiency, saves welding time and significantly improves the welding quality.
Circular Seam Preparation and Root Opening
Special Pipe Fabrication
Boost Your Pipe Production
Your pipe production gets a boost in productivity
when PEMA’s rollerbeds, welding C&B, welding automation systems and engineering solutions are utilized.
Longitudinal pipe sections can be welded outside by our Multi-Arc SAW portals and inside by our long reach welding booms.
Longitudinal and circumferential welding
We have dedicated welding automation solutions for longitudinal
welding of tubular pipes, pipe-to-pipe, elbow-to-pipe and flange
to pipe connections. Our positioners and welding column & boom
solutions combined with special welding automation can be selected from our wide range of standard modular product families.
Various welding processes such as GMAW or GTAW for root pass
welding and Multi-Arc SAW welding for filling up are integrated in
our pipe fabrication equipment.
Efficient welding head and motorized slide modules have been
developed to fulfill the technological needs that are required to
automate the welding of different size geometries and designs.
You can choose from a wide range of PEMA positioners and the
appropriate model and machine can be equipped with custom-made clamping devices.

Pipe Component Fabrication
Pipe component fabrication is one of the most demanding pipe manufacturing phases
When implemented well, the process is fast and brings immediate results in production capacity and end quality.
Fast process, immediate results
The offering of automated PEMA welding and production solutions cover welding heavy and thick walls in pipe elbows and assemblies, such as valve frame welding.
Our experts optimize the right handling equipment and welding Column & Boom from our extensive selection of modular product families.
Various welding processes such as GMAW or GTAW for root pass
welding and Multi-Arc SAW welding for filling up are integrated inour pipe fabrication equipment.
A specific range of Column & Booms are designed for internal
welding of pipe elbow segments as well for external welding
operating in integration with PEMA Positioners.

Dish End Production
Integrated welding and cladding
Integrated welding and cladding processes are combined to our Column & Boom and together with the interpolated movement these processes are available for both internal and external surfaces.
The extremely demanding quality requirements of manufactured
pressure vessels are achieved by using high-quality production
equipment to ensure a stable and fully controlled welding process.
PEMA has extensive knowledge in building high-precision, large
scale machinery with up to 250 tons of positioners and numerically controlled column & booms and welding platforms, and fully integrating modern digitally controlled Submerged Arc Welding equipment. These integrated solutions create a combination that ensures an increase in productivity, solid quality and uncompromised safety.
Integrating a Multi-Arc SAW carriage and positioner in an advanced control system, i.e. the interpolation of the welding head and positioning the dish end, allows the welding of semi-elliptical dish ends and hemispherical heads to be automated. Real time control of the welding orientation and welding speed is something unique we have developed as a solution for our customers in the industry.

Pressure Vessel Production
Specially designed solutions for vessel manufacturing ensures efficiency and quality throughout the production line
PEMA solutions cover all welding and material handling needs during these phases.
Highest safety
Heavy vessel production automation requires rigid rollerbeds and
large size welding Column & Booms or welding platforms. The
semi-narrow gap SAW technique is used on welding exceptionally
thick plate, 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 rollerbeds come with an automatic hydraulic anti-creep function to prevent axial movement.

PEMA Nozzle Welding
Nozzle Welding Station
Solution for pressure vessels.
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 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 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 rate and saves manual welding hours typically required for a time-consuming and demanding multi-layer welding procedure.
