02.5Machining & Fabrication

Welding with structural integrity and full traceability.

Welded joints with performance and traceability: qualified procedures (WPS/WPQ) and quality engineering (DOE, 8D) to deliver durability and safety.

01Overview

Processes and control

We master critical processes — MIG/MAG (GMAW), TIG (GTAW), resistance welding and structural welding — in materials that demand strict control of temperature and heat input.

Every joint is planned before execution: DFMAA optimizes access, minimizes thermal distortion and plans post-weld inspection. Welding procedure specifications (WPS) and qualified welders (WPQ) ensure the consistency of every bead.

02Welding

Where we add value

  • 02.5.1

    Heavy-duty and critical structures

    Fabrication and repair of steel structures, large machine bases and supports subject to vibration and high loads, where weld failure is unacceptable.

  • 02.5.2

    Pressure vessels and boilermaking

    Welding of parts operating under high pressure and temperature, with non-destructive testing and weld traceability.

  • 02.5.3

    Technical subassembly

    Integration of machined and laser-cut parts into complex subassemblies, securing the geometric integrity of the assembled product.

03Welding

Benefits

  • Lower total cost

    An optimized process that reduces rework and gas consumption.

  • Precision and reliability

    Joints with integrity verified by inspection.

  • Speed and know-how

    Qualified procedures that sustain lead time and quality.

  • Fewer failures

    Full traceability and problem prevention through the 8D method.

04Methods applied

Quality engineering applied at every step — from design to delivery.

Explore Integrated Engineering
  • DFMAA Design for Manufacturing, Assembly and Automation

    The joint is analyzed before execution to optimize access, minimize thermal distortion and plan post-weld inspection — stronger, more economical joints.

  • DMAIC Define · Measure · Analyze · Improve · Control

    The welding process is continuously measured and improved, holding the quality standard from the first bead to the last.

  • DOE Design of Experiments

    Used to qualify new procedures and materials, tuning current, voltage and travel speed to secure metallurgical quality and minimize porosity and cracking.

  • PPAP Production Part Approval Process

    Welding of critical components is documented, including the filler metal certificate of analysis and welder qualification.

  • 8D Eight Disciplines method

    A joint deviation triggers an 8D to find the root cause — such as contamination or an incorrect procedure — and implement corrective and preventive actions.
