What We Do
Welding Capabilities
We offer three welding processes under one roof — laser welding for precision and cosmetic joints, TIG for high-quality visible welds, and MIG for structural volume work. The right process is selected per application.
0.1 – 0.8mm
Laser Weld Bead Width
bead width; material and thickness dependent
Narrow bead width minimises distortion on thin sheet and precision enclosures. Ideal where adjacent surfaces must remain flat.
2000×1000 mm
Max Assembly Size
max assembly envelope
Welded assemblies up to full structural frame size. Large jigs available for long linear welds and box structures.
Up to 12mm
Single-Pass Penetration
laser single-pass; TIG/MIG up to 25mm+
Deep penetration without multiple passes reduces heat input and distortion. Thick plate uses multi-pass TIG or MIG.
All types
Joint Types
butt · lap · T-joint · corner · fillet
Butt, lap, T-joint, corner, edge, and fillet welds. Laser welding especially suited to butt and lap joints on thin sheet without filler.
Laser + TIG + MIG
Processes Available
all three in-house — process selected per job
Fibre laser welding for precision and cosmetics. TIG (GTAW) for high-quality visible joints. MIG (GMAW) for structural volume production.
Custom jigs
Jigged Assembly
built in-house for each assembly type
Custom weld jigs and fixtures hold parts in dimensional position during welding — critical for angular accuracy and repeat consistency across batch.
Materials
Metals We Weld
10+ weldable alloys processed in-house. Filler rod selection, shielding gas, and pre/post-weld treatment are matched to each material to ensure full-strength, defect-free joints.
Stainless Steel 304 / 316
TIG / Laser
Austenitic SS — full penetration TIG welds for structural joints; laser welding for cosmetic and precision enclosure seams. Post-weld passivation available.
Mild / Carbon Steel
TIG / Laser
S275, S355. MIG for structural frames and high-volume fabrication; TIG for cleaner visible joints. Welded assemblies up to 25 mm plate.
Aluminium 5052 / 6061
TIG / Laser
AC TIG with pure argon shielding. Enclosures, frames, marine brackets. 6061-T6 heat-affected zone managed with pre-heat sequencing.
Stainless Steel 316L
TIG / Laser
Semiconductor process tubes, optical windows. Requires specialised CO₂ parameters.
Duplex Stainless Steel
TIG
2205, 2507. High strength and corrosion resistance for offshore and chemical plant. Inter-pass temperature control critical to maintain duplex microstructure.
Tool Steel / Hardened Steel
Laser
Repair welding on mould cavities, die edges, and hardened fixtures. Laser welding minimises HAZ and avoids annealing of the surrounding hardened zone.
Aluminium 7075 / 2024
Laser
High-strength aerospace alloys — difficult to TIG weld due to hot-cracking. Laser welding with tight parameter control achieves sound joints.
Copper & Brass
Laser
High thermal conductivity makes TIG/MIG difficult. Laser welding delivers focused energy for clean lap and butt joints on copper bus bars and brass fittings.

Where Welding & Assembly is Used
Welding is the bridge between cut parts and finished assemblies — from precision medical enclosures that must be hermetic to structural offshore frames designed for decades of service.
Industrial Automation
Machine Frames & Structural Assemblies
Welded mild and stainless steel machine bases, gantry frames, conveyor structures, and equipment mounting frames. MIG welding for structural volume; TIG for visible joints and stainless finishing.
Semiconductor & Electronics
Precision Enclosures & Chambers
Laser-welded stainless steel enclosures, vacuum chamber sections, and shielded housings. Narrow bead and minimal distortion preserve dimensional accuracy for mating flanges and sealing surfaces.
Marine & Offshore
Structural & Pipe Fabrication
316L stainless and duplex steel pipe spools, structural brackets, and module support frames. Purge-back TIG welding for full-bore pipe joints; weld maps and inspection documentation available.
Medical & Cleanroom
Hygienic Welded Assemblies

What Makes Our Welding & Assembly Different
Welding quality is invisible until it fails. We design the process — jig, sequence, parameters, post-weld treatment — to ensure joints that hold for the life of the assembly.
Cut, Bend and Weld from One Supplier
Our laser cutting, CNC bending, and welding are all in-house. Laser-cut and bent components go directly to welding — no inter-supplier dimensional variation, no re-measurement, no split delivery. Your assembly is dimensionally consistent because every upstream operation is ours.
Jigged for Dimensional Accuracy Across Batches
For repeat assemblies, we build custom weld jigs that locate every component in the correct position before the first arc is struck. This eliminates angular variation and ensures every unit in a batch is dimensionally identical — critical for assemblies that must mate with customer equipment in the field.
Laser Welding for Precision & Cosmetic Joints
Laser welding produces a bead as narrow as 0.1 mm with minimal heat input — far less distortion than TIG on thin sheet. For precision enclosures, cosmetic visible seams on brushed stainless steel, and joints near heat-sensitive components, laser welding is the correct process. We recommend it where dimensional stability and appearance matter most.
Post-Weld Treatment Included
We don't just weld and ship. Depending on your application, we offer weld spatter removal, slag grinding, weld bead dressing, passivation for stainless steel, and surface finishing to Ra ≤ 0.8 μm. The right post-weld treatment is included in the quote — you don't need to find a separate finisher.
Laser Welding vs TIG vs MIG — When to Use Each
All three processes are available in-house. The right choice depends on material, thickness, joint access, and finish requirements.

FAQ
Welding & Assembly Questions
These are some of the common questions customers ask before sending drawings or requesting quotation.
When should I choose laser welding over TIG welding?
Choose laser welding when you need minimal distortion on thin sheet (under 3 mm), a very narrow weld bead for cosmetic or precision joints, high-speed welding on repeat production runs, or when the joint is in a location where TIG torch access is limited. TIG is better for thicker material, joints requiring filler rod for gap-bridging, and when a wider, more robust bead is acceptable. For most precision enclosures and thin-wall stainless steel work, laser welding is the correct choice.
Do you provide weld inspection and documentation?
Yes. We offer visual weld inspection per ISO 5817, dimensional inspection reports, and weld maps for structural assemblies. For marine and offshore customers we can provide material traceability certificates and mill certificates for base material and filler rod. Dye penetrant (DP) testing and pressure/leak testing are available on request. Please specify your documentation requirements when quoting so we can include them in the scope.
Can you weld aluminium with TIG?
Yes. Aluminium TIG welding uses AC current with pure argon shielding to break the oxide layer. We weld 5052, 6061, and 1100 series regularly. 6061-T6 loses strength in the heat-affected zone — for structural applications where strength is critical, we can advise on post-weld heat treatment or design changes that minimise the HAZ impact. 7075 and 2024 are prone to hot cracking with TIG; for these alloys we recommend laser welding with controlled parameters.
What post-weld treatments do you offer?
We offer weld spatter removal, weld bead grinding and blending, passivation of stainless steel (citric acid or nitric acid per ASTM A967), electropolishing for hygienic surface finishes, and surface grinding to specified Ra values. For food-grade and pharmaceutical assemblies, we can achieve Ra ≤ 0.8 μm on weld zones. All treatments are included in the quote — you receive a finished assembly, not a raw welded part that needs further processing elsewhere.
Do you supply the base material or should I provide cut parts?
Both approaches work. For full-service jobs, we laser cut, CNC bend, and then weld in-house from your 3D model — one supplier, one delivery. If you have parts already cut elsewhere, we can receive them and weld to your assembly drawing. For batch repeat assemblies, supplying your own cut parts is also fine — just ensure parts arrive deburred and dimensionally verified to your drawing before delivery.
Can you weld dissimilar metals?
Some dissimilar metal combinations are weldable with the right filler selection — for example, 304 SS to mild steel using austenitic filler (ER309), or copper to stainless using laser welding with a transition layer. Others, such as aluminium to steel, are generally not weldable by fusion methods due to intermetallic compound formation. If you have a dissimilar metal joint requirement, send us the material combination and joint geometry and we’ll advise on feasibility and the recommended approach.
