METAL FABRICATION

BOILERMAKING IN FOCUS

Turning Metal Sheets into Functional Components.

Industrial boilermaking involves preparing, cutting, forming, fitting and assembling metal components. The work depends on material thickness and grade, geometry and the component’s intended function.

Feasibility is assessed using the available documentation and required resources. For pressure equipment, hazardous-fluid storage or equipment subject to specific regulations, engineering, materials, fabrication procedures and inspections must meet applicable requirements.

Custom Components

Fabrication to validated drawings and dimensions.

Fabricated Assemblies

Assembly of multiple components to specification.

Metalwork Repair

Prior assessment of condition and repairability.

W / 04 FABRICATION PROCESS

ASSESSMENT

Requirement Review

Review of drawings, dimensions, materials, quantities, tolerances and working conditions.

PREPARATION

Component Preparation

Material preparation, marking, cutting, edge preparation and fitting.

EXECUTION

Welding and Assembly

Execution according to the procedures and technical requirements applicable to the project.

VERIFICATION

Inspection and Finishing

Specified inspections, finishing, identification and preparation for delivery.

TECHNICAL REQUIREMENTS

A Joint Is More Than a Weld Bead.

Material selection, preparation, procedure, working conditions and inspection all influence final quality.

Suitable Materials

Material identification and verification of suitability for the application and project documentation.

Joint Preparation

Edge preparation, alignment, fitting and assembly conditions according to applicable requirements.

Weld Inspection

Visual inspection and, where required, other examination methods specified by the project requirements.

Document Traceability

Records and inspection documentation according to the agreed traceability level for the work.

PROJECT-DEFINED INSPECTION

Inspections Appropriate to the Component’s Intended Use.

Required inspections are determined by joint type, client requirements, applicable standards and the consequences of failure. Specialized non-destructive testing should be scoped according to the agreed work and available resources.

HEALTH, SAFETY AND ENVIRONMENT

Risk Control Is Part of the Work.

Welding and boilermaking require risk-based preparation for hazards such as sparks, radiation, fumes, fire, material handling and the use of tools or machinery.

Depending on the task, measures may include permit verification, ventilation, personal protective equipment, fire protection, energy isolation and work-area control.

FREQUENTLY ASKED QUESTIONS

Your Welding or Boilermaking Project.

To prepare a suitable proposal, share available drawings, materials, quantities and working conditions.

Request an Assessment ↗

Can you work from our drawings? +

Yes. Drawings can be used to assess the requirement. Reviewing them helps confirm dimensions, materials, joints and necessary inspections.

What types of components can you assess? +

Depending on validated resources and scope, requirements may include welded assemblies, metal components, shells, supports or boilermaking products.

Can you repair a cracked or deformed component? +

A prior technical assessment is required to identify the likely cause, material condition, component function and acceptable repair method.

Do you perform non-destructive testing? +

Required methods and inspection levels must be defined in the project scope. Specialized testing must be confirmed separately according to available capabilities and resources.
