EN 287-1 Welding Qualifications

Our welding qualifications cover a wide range of materials and methods according to EN 287-1 standards:
Group 1.3, 9.1, 11

  • 1.3: Unalloyed (carbon) steels and fine-grain steels
    General structural steels, weldable and widely used in construction and industry.

  • 9.1: Nickel and nickel alloys
    High corrosion and heat resistance, often used in chemical and marine industries.

  • 11: Aluminium and aluminium alloys
    Lightweight, corrosion-resistant, used in transport, aerospace, and marine applications.

Group 8, 9.2, 9.3, 10

  • 8: Austenitic stainless steels
    High corrosion resistance, commonly used in food, pharmaceutical, and chemical industries.

  • 9.2: Austenitic-ferritic (duplex) stainless steels
    High strength and corrosion resistance, often in offshore and pressure applications.

  • 9.3: Precipitation-hardening stainless steels
    High strength after heat treatment, used in aerospace and high-performance tools.

  • 10: Copper and copper alloys
    Excellent thermal and electrical conductivity, used in electrical and plumbing applications.


Group 51–54, 61–62

  • 51–54: Titanium and titanium alloys
    Lightweight, strong, and highly corrosion-resistant, widely used in aerospace and chemical processing.

  • 61–62: Zirconium and zirconium alloys
    Extremely corrosion-resistant, used in nuclear and chemical industries.
111 – Manual Metal Arc Welding (MMA / SMAW)

Also called stick welding, this process uses a
consumable electrode coated in flux to lay the weld.

  • Common for: Structural steel, maintenance, and outdoor work.
  • Shielding: Provided by the flux coating.

135 – MAG Welding with Solid Wire

Metal Active Gas welding (MAG) using a solid wire electrode.
Often used for carbon and low-alloy steels.

  • Common for: Production welding and fabrication.
  • Shielding gas: Typically CO₂ or a mix with Argon.

136 – MAG Welding with Flux-Cored Wire

Similar to 135 but uses a tubular wire filled with flux instead of a solid wire.

  • Advantage: Higher deposition rate and better weld penetration.
  • Shielding: External gas and internal flux.

138 – MAG Welding with Metal-Cored Wire

A variant of MAG using metal-cored wire,
combining benefits of solid and flux-cored wires.

  • Efficient for: High-speed applications with excellent appearance.
  • Shielding: External gas (typically Ar/CO₂ mix).

141 – Tungsten Inert Gas Welding (TIG / GTAW)

Uses a non-consumable tungsten electrode and an inert gas shield (usually Argon).

  • Known for: High-quality, precise welds.
  • Ideal for: Thin materials, stainless steel, titanium, aluminium.
  • Slower and requires more skill.

142 – Mechanized TIG Welding

Same as 141 but automated or semi-automated.

  • Used in: Pipelines, precision components.
  • Offers consistency over long welds.

143 – Plasma Arc Welding (PAW)

An advanced form of TIG where the arc is constricted
through a fine nozzle, creating a high-energy plasma jet.

  • Suitable for: High-precision work, especially thin materials.
  • Requires more complex equipment.

145 – Laser Beam Welding (LBW)

A high-energy laser beam is used to melt and join materials.

  • Ultra-precise, very fast, with minimal heat distortion.
  • Used in: Aerospace, automotive, microelectronics.
Our certifications include:

We are certified to perform welding in accordance with WPQR (Welding Procedure Qualification Record) standards, ensuring high-quality and reliable welds for a wide range of materials.
