Pemamek - Welding, Automation and Mechanisation Solutions for Shipyards

Pemamek Oy is a world-leading company specialising in the supply of heavy welding mechanisation and automation solutions for efficient shipyard production all over the world.

Know-how and a competitive edge at Pemamek rest not only on long-term experience but in the bold application of new technologies as well. The guiding stars behind our products are client-related competitive ability, quality in production, ergonomics, and safety.

Pemamek operates in international welding automation markets. Our wide range of products is found in over 50 countries and in all continents.

Shipyard Automation Production Equipment

Maintaining a competitive edge at shipyards requires efficient production. Improvement in cost effectiveness frequently means an increase in automation. Pemamek can offer complete, modern and productive production lines for flat panels, double hulls, subassembly panels or just sections of them.

The PEMA shipbuilding production automation range is comprised of:

• Plate and profile prefabrication systems
• Flat-panel production lines
• Double-bottom production lines
• Subassembly production lines (micro, bulkhead)
• Curved section panel lines
• Robotised panel lines or production cells for welding or cutting
• Production logistics and data collection software

Shipyard Production, Flow and Capacity Consultation

Through partners and its own organisation, Pemamek can also offer a variety of consultation services, including the design of yard production facilities, and flow and capacity studies.

Vision Robot Welding Portal (VRWP)

The welding of panel lines, normally fillet welding, can be robotised by means of PEMA VRWP robot welding gantries. The VRWP gantries consist of a robust robot welding gantry with three external robot axes, six-axis welding robot, welding equipment and vision system-based robot programming.

Machine Vision Programming is a unique on-line programming method which features:

• Short programming time
• Easy system support by a qualified welder
• High utility ratio, thanks to working with real workpiece
• No typical off-line programming problems
• Low investment cost

These user-friendly robot gantries can raise the productivity of a panel production line significantly, thanks to a very high arc time ratio (over 80%) and utility ratio (100%).

Also, other programming methods can be applied to robot welding. Macro or off-line programming systems are available in various robot applications for shipyard production.

PEMA Vertical Welding Station (VWS)

The PEMA VWS features a height-adjustable welding platform with four vertical welding arms.

Normally this platform with carriage is supported by a mobile gantry. The VWS is ideal in welding of vertical seams of double bottom cross-sections, high bulkheads or various frame sections.

Main features:

• PLC-controlled automatic welding simultaneously with four welding heads
• On-line adjustment of welding parameters (V, A, speed), oscillation and jump-over of horizontal stiffeners
• Motorised rotation of welding heads ±45°
• Replaces 8-14 manual welders (or two robots)
