The extremely demanding quality requirements of manufactured pressure vessels are achieved by using high-quality PEMA production equipment to ensure a stable and fully controlled welding process.
PEMA heavy dish end welding automation
Our four decades of experience in extra-heavy-duty positioner solutions and Multi-Arc SAW welding with column & booms or platforms is widely used in the Process & Nuclear Industry. 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 a wealth of knowledge in building high-precision, large-scale machinery with up to 250 tons of positioners and numerically controlled column and booms and welding platforms, and fully integrating modern digitally controlled Submerged Arc Welding equipment. These 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, allows the welding of semi-elliptical dish ends and hemispherical heads to be automated. Controlling welding orientation and welding speed is something we have studied as a solution for our customers in the industry.
