Our Welding & Assembly Capabilities
BSG manages the entire fabrication process (cutting, welding, and assembly under one roof) to reduce supply chain bottlenecks and deliver ready-to-use components.
Robotic Welding
High-speed, high-volume robotic welding cells deliver consistent weld quality across large production runs. The process is ideal for repeatable geometries, ensuring cost-efficiency and tight tolerances with minimal heat distortion.
MIG/MAG & TIG Welding
Skilled, certified welders handle complex geometries and produce superior aesthetic finishes without the need for post-weld grinding. TIG welding excels on thin stainless steel and aluminium, while MIG/MAG is better suited to longer production runs.
Spot & Stud Welding
Precision resistance spot welding and stud welding for thin sheet metals. These processes deliver fast cycle times, zero filler material waste, and minimal distortion, perfect for enclosures, brackets, and lightweight assemblies.
Mechanical Assembly
Complete end-to-end assembly including installation of hinges, handles, and mechanical components, automated PEM nut and stud pressing, riveting, hardware insertion, kitting, labeling, and protective packaging, ready for end-user delivery.

Materials & Thickness Ranges
We weld and assemble a full range of sheet metals with strict quality control: 100% visual inspection, weld penetration testing, and CMM dimensional accuracy checks.
| Material | Grades / Types | Min Thickness | Max Thickness | Typical Applications |
|---|---|---|---|---|
| Stainless Steel | 1.4301 (304), 1.4404 (316L) | 1.0 mm | 15 mm | Enclosures, food-grade components, chemical equipment |
| Aluminium | 5754, 5083, 6061, 6082 | 1.0 mm | 12 mm | Lightweight housings, heat sinks, transport equipment |
| Mild Steel (Carbon) | S235, S275, S355 | 1.0 mm | 15 mm | Structural frames, machine bases, brackets |
| Galvanized Steel | DX51D, DX52D | 0.8 mm | 3.0 mm | Outdoor enclosures, HVAC, corrosion-resistant panels |
For materials thinner than 1.0 mm, specialized spot welding, stud welding, or precision riveting is used to prevent heat distortion and warping.
