What are special welding services?
Special welding refers to welding processes that go beyond standard manual methods, such as TIG or MIG. These advanced techniques are used when extreme accuracy, repeatability, or the handling of complex alloys is required.
At M.E.G.A., special welding covers a range of automated and semi-automated procedures, performed under rigorous quality control to guarantee metallurgical integrity and dimensional precision.
Our main processes include:
- TIG and Hot Wire TIG (TIGer technology) – ideal for achieving smooth, high-quality welds with minimal dilution, suitable for corrosion-resistant overlays and precision joints.
- GMAW (Gas Metal Arc Welding) – used for high-deposition applications and large components, offering excellent control and speed.
- Submerged Arc Welding (SAW) – ensuring deep penetration and consistent quality on thick-wall materials.
- Cladding and Weld Overlay – the deposition of corrosion-resistant alloys (such as Inconel 625, Incoloy 825, or Hastelloy C22) on carbon or low-alloy steel components to extend service life in corrosive environments.
These special welding processes are applied using automated systems with CNC-controlled equipment, ensuring constant monitoring of parameters such as temperature, speed, and bead geometry.

Advantages of M.E.G.A.’s special welding
Our welding department is fully integrated within our production cycle, from forging to machining, heat treatment, and final inspection, ensuring full traceability and process control.
Key benefits include:
- High precision and repeatability thanks to automated processes and dual-torch TIGer systems.
- Superior metallurgical quality, with controlled dilution and optimal bonding between base and overlay materials.
- Efficiency and speed, with multi-layer cladding achieved in a single pass.
- Compatibility with all major alloys, including carbon steels, stainless steels, duplex/super duplex, nickel alloys, and titanium.
- Compliance with international standards such as ASME, EN, PED, and NORSOK.
Applications across industries
M.E.G.A.’s special welding services are applied in projects that demand uncompromising quality and mechanical performance, including:
- Oil & Gas: corrosion-resistant overlay for flanges, tees, and piggable wyes.
- Petrochemical and Power Generation: weld overlays for pressure vessels, heat exchangers, and pipes exposed to aggressive media.
- Subsea and Offshore: structural welding and cladding for forged components subjected to high pressure and fatigue.
- Nuclear and Energy: welding of components in compliance with ASME Section III and RCC-M codes.
A fully integrated welding division
M.E.G.A.’s welding services are not standalone operations—they are part of a vertically integrated production chain that includes design (FEA analysis), forging, mechanical machining, non-destructive testing (PT, UT, MT, RX), and certified documentation.
All activities are carried out in-house by certified welders and under the supervision of qualified welding engineers.
Why choose M.E.G.A. for special welding
With over six decades of experience and continuous innovation, M.E.G.A. is able to design and manufacture any type of custom fitting, developed according to the client’s specific requirements and applicable international codes. Every special component can then be completed with in-house welding and weld overlay operations, performed by certified personnel to ensure maximum precision, safety, and durability in the final product.
