Welding and Fabrication

DMI Dubai’s welding and fabrication shop has various welding processes to cater to different applications and materials, these processes include:

• Tungsten inert gas (TIG) welding
• Metal inert gas (MIG) welding
• Electric arc welding
• Submerged arc welding (SAW)
• Fusion welding
• Plasma transferred arc (PTA)

Our trained and qualified welders have procedure approvals for fabricating numerous different materials. DMI Dubai’s fabrication yard commonly fabricates components like gate valves, dredger parts, buckets and silos. The fabrication team is able to complete jobs as per:

• Drawings provided by the customer
• Reverse engineering fabricated components
• Repairing broken or cracked components

More about welding and fabrication

The welding and fabrication department caters to a various industries and services numerous different products including:

• Marine: Piston crowns, exhaust valve spindles & seats and cylinder covers.
• Dredging: Dredger structures, suction doors and gate valves.
• Desalination: Storage tanks in structural steel & stainless steel.
• Power: Piping and ducting works (water, fuel and exhaust)
• Transport & earth-moving: Excavator buckets, boom and track pads.
• Cement/crusher: modification of equipment and plants.

Plasma Tranferred Arc (PTA)

Plasma Transferred Arc (PTA) is a process that creates a small heat affected zone (HAZ) with a short arc and thus transfers less heat to the component. This produces high quality deposits with optimal protection, minimal dilution and deformation of the base material. Components such as exhaust valve spindles and seats, gate valves, butterfly valves, mechanical seals and extruder screws are repaired with Stellite, SS, Ni base alloys using PTA.
