WELDING & FABRICATION – WORKFLOW & INTEGRATION

At LGM Engineering we provide precision MIG and TIG welding, alongside spot welding and projection welding to attach weld studs, nuts or fastening parts, delivering strong, clean and consistent joints across a wide range of materials and thicknesses. Our welding capability supports both structural and cosmetic requirements, ensuring assemblies meet mechanical performance needs while maintaining a high standard of finish where appearance is critical.

We weld mild steel, stainless steel and aluminium, working with a broad range of grades to suit structural, industrial and bespoke fabrication applications. Spot welding and stud projection welding are used where appropriate to provide fast, repeatable joining for sheet metal components and threaded fixings. Careful control of heat input, joint preparation and weld sequencing allows us to minimise distortion, manage material behaviour and maintain dimensional accuracy on both small components and larger assemblies.

Our experienced fabricators work to clearly defined welding procedures, ensuring repeatable weld quality across prototype parts and production batches alike. This disciplined approach delivers reliable results, whether the requirement is a single bespoke fabrication, integrated studded components or repeat-run welded assemblies.

Our welding workflow is designed to support everything from one-off prototypes through to short and medium production runs. CAD-driven drawings and clear fabrication data ensure joints, tolerances and assembly sequences are fully understood before welding begins, reducing rework and improving consistency across batches.

Welding and fabrication are fully integrated with upstream and downstream processes including laser cutting, press brake folding, finishing and assembly. By carrying out these operations under one roof, we reduce handling, maintain tighter quality control and ensure components progress smoothly through manufacture.

This integrated approach allows us to deliver welded components and assemblies that arrive ready for installation or final use, with reliable lead times, consistent quality and competitive pricing across both prototype and production work.

Welding & Fabrication Capabilities

Welding Processes

We provide both MIG, TIG, Spot And Projection welding, allowing the welding process to be matched to the material, joint design, and finish requirements of each component or assembly.

Material Thickness

Our welding capability covers a wide range of material thicknesses, from light-gauge sheet through to heavier sections, supporting both precision work and structural fabrication.

Repeatability

Defined welding procedures and experienced fabricators ensure consistent weld quality and repeatability across both prototype parts and production batches.

Mild Steel

We MIG and TIG weld mild steels used in general engineering and structural fabrication, producing strong, reliable joints suitable for frames, brackets, and welded assemblies.

Stainless Steel

We TIG and MIG weld stainless steels including 304 and 316, delivering clean, controlled welds for functional, hygienic, and cosmetic applications.

Aluminium

We TIG and MIG weld aluminium grades commonly used in fabrication, applying controlled heat input to minimise distortion and maintain dimensional accuracy.

Fabricated Assemblies

Welding is fully integrated with cutting, folding, and finishing processes, allowing complete fabricated assemblies to be produced under one roof with consistent quality control.

Prototype & Production

Our welding setup supports both one-off prototypes and short to medium production runs with consistent quality.

Integrated Fabrication

Welding is fully integrated with laser cutting, folding, and finishing, allowing complete fabricated components to be produced under one roof.

Integrated Laser Cutting and Press Brake Folding

Maximise efficiency by combining laser cutting and press brake folding within a single, controlled workflow. We take your designs from flat sheet through to accurately formed components, maintaining precision and consistency at every stage.

  • Precision cutting preparation – CNC laser cutting of mild steel, stainless steel, and aluminium, accurately cut to size for forming

  • Custom cut components – Laser cut blanks produced to suit specific bend allowances and fold sequences

  • Accurate press brake folding – Multiple controlled bends and folds carried out on laser-cut parts using modern press brake equipment

  • Optimised blanks – Laser cut components sized and prepared to ensure efficient, repeatable press brake operations

By carrying out laser cutting and press brake bending under one roof, we reduce handling, shorten lead times, and maintain tighter quality control, resulting in reliable, cost-effective folded components.

Welding & Fabrication FAQ’s

We regularly weld:

  • Mild steel

  • Stainless steel

  • Aluminium

If you’re unsure about a specific grade or finish, send the details and we’ll confirm suitability.

We use MIG and TIG welding, depending on material, thickness, joint type and the required finish.

Yes. We offer spot welding where it is suitable for fast, repeatable joining of sheet metal components.

Yes. We can use projection welding to attach items such as weld studs, weld nuts and fastening components, where appropriate.

Yes. We weld for both strength/functional performance and appearance-critical applications. If the weld finish is cosmetic, tell us upfront so we can plan the method and preparation accordingly.

Welding introduces heat and movement, so tolerances are typically less tight than laser cutting or folding.

We control accuracy through:

  • Correct joint preparation

  • Fixturing and clamping

  • Weld sequencing to reduce distortion

If you have critical dimensions, highlight them at quote stage.

Yes. We work to customer drawings and fabrication information, and can accept most common CAD file formats where required. The clearer the datum points, tolerances and weld requirements, the faster we can quote and the more consistent the results will be.

For more detail on supported file formats and drawing preparation, please see our CAD-CAM page.

Yes. We can supply:

  • Welded sub-assemblies

  • Complete fabricated components

  • Repeat-run welded assemblies

To quote accurately, please provide:

  • Drawings / models (and any fabrication notes)

  • Material and thickness

  • Quantity

  • Any critical dimensions or cosmetic areas

  • Whether studs/nuts/fasteners are required

Yes. We support:

  • One-off prototypes

  • Small batch work

  • Short, medium and large production runs
