Welding Services
Professional welding and fabrication services for structural assemblies, pressure components, and precision weldments. MIG/MAG, TIG, spot welding, and robotic welding performed by certified welders to European standards.
Overview
Structural Strength, Precision Joints
MegaMETA provides comprehensive welding services for carbon steel, stainless steel, and aluminum assemblies. Our welding operations are supported by qualified Welding Procedure Specifications (WPS) and performed by certified welders holding valid qualifications per EN ISO 9606.
From single-piece weldments to serial production of structural fabrications, we maintain consistent quality through documented procedures, in-process controls, and thorough final inspection including non-destructive testing when required. Our skilled machinists also provide post-weld machining to achieve precise final dimensions on welded assemblies.

Welding Methods
Processes for Every Application
Process 135/136
MIG/MAG Welding
High-productivity semi-automatic and mechanized welding for carbon and stainless steel. Ideal for structural fabrications and serial production of medium to heavy assemblies.
Process 141
TIG Welding
Precision welding for stainless steel and aluminum requiring high-quality weld appearance and full penetration. Used for thin-wall assemblies, pipes, and food-grade components.
Process 21
Spot Welding
Resistance spot welding for joining sheet metal components. Fast cycle times and consistent weld quality make this process ideal for high-volume sheet metal assemblies.
Process 52
Laser Welding
High-energy focused beam welding delivering deep penetration with minimal heat-affected zone. Produces narrow, precise weld seams with low distortion — ideal for thin-wall components, automotive parts, and assemblies requiring minimal post-weld finishing.

- Welding Procedure Specifications (WPS) per EN ISO 15614
- Welding coordination per EN ISO 14731
- Visual inspection per EN ISO 5817 (quality levels B, C, D)
- Non-Destructive Testing: penetrant testing (PT), magnetic particle testing (MT), ultrasonic testing (UT)
- Dimensional inspection and geometric tolerance verification
Fabrication
Weldment Assemblies & Structural Fabrication
Assembly
Machine Frames & Bases
Heavy-duty welded frames for industrial machinery. Stress-relieved and machined to flatness tolerances after welding for accurate equipment mounting.
Structural
Structural Steel Fabrication
Platforms, supports, brackets, and structural components fabricated from standard and custom profiles. Supplied primed or with specified surface treatment.
Precision
Precision Weldments
Tight-tolerance welded assemblies where post-weld machining achieves final dimensions. Fixtures and jigs used to control distortion during welding.
Process
Welding Production Workflow
1
Drawing Review & WPS Selection
We review your assembly drawings, identify weld joint types, and assign qualified Welding Procedure Specifications for each joint configuration and material combination.
2
Material Preparation
Components are cut, formed, and prepared for welding. Joint edges are prepared to the geometry specified in the WPS. Fixtures are built for complex assemblies.
3
Tack Assembly & Fit-Up
Components are tacked in position using fixtures and jigs. Fit-up dimensions are verified before committing to final welding to ensure correct alignment.
4
Welding
Certified welders execute the welds per the approved WPS. Welding sequence is controlled to minimize distortion. In-process parameters are monitored.
5
Inspection & Testing
Visual inspection of all welds per EN ISO 5817. NDT (PT, MT, UT) performed where required. Dimensional verification of the completed assembly.
6
Finishing & Delivery
Post-weld treatments including stress relief, surface preparation, and coating as specified. Completed assemblies are packaged and shipped with full documentation.
FAQ
Frequently Asked Questions
We provide MIG/MAG, TIG, submerged arc (SAW), spot welding, and laser welding. The process is selected based on material type, joint design, and production volume requirements.
We weld mild steel, carbon steel, high-strength steel alloys (Strenx, HARDOX), stainless steel (304, 316, duplex), and aluminum alloys across a range of thicknesses.
Our welding operations are certified to ISO 3834 and our welders hold qualifications per EN ISO 9606. We also work to client-specific WPS and WPQR requirements.
Yes. Welded assemblies can be finish-machined through our CNC machining partners for tight tolerances on mounting faces, bore alignments, and critical datum surfaces.
We perform visual inspection (VT), dimensional checks, and can arrange non-destructive testing including ultrasonic (UT), radiographic (RT), and dye penetrant (PT) examination as required.
Yes. We handle everything from precision-welded brackets and housings to large fabricated frames and structural steel assemblies, with appropriate jigging and fixturing.
Laser welding provides deep penetration with minimal heat-affected zone, narrow seam widths, low distortion, and high processing speed — ideal for precision assemblies and thin-wall components.
