People who ask us for a welding quote often have the same question: “TIG or MIG — which is better?”. The honest answer is: it depends on the part. They are two different processes with different strengths, and choosing the right one makes a difference in quality, lead time and cost. Let’s look at them in plain terms.

TIG welding: precision and clean results

In TIG welding the arc is struck from a non-consumable tungsten electrode, and the filler metal is added separately, with a high degree of control. It is the most precise process: thin, clean, almost decorative beads and well-controlled heat input. We choose it for thin materials, exposed stainless steel, aluminum alloys and every case where the joint must look flawless — furniture, food industry, high-end parts.

MIG welding: productivity and strength

In MIG welding the filler wire feeds continuously and acts as the electrode itself: the process is faster and suits thicker materials and series production. It is the right choice for structural fabrication, frames, brackets and any job where strength and turnaround time matter most.

How we choose in the shop

• Thin material or visible joint → TIG
• Medium to heavy thickness, series, structures → MIG
• Aluminum → either, depending on thickness and required finish

At LY-CO we perform TIG and MIG welding on all steels and aluminum alloys, often combining both in the same project: MIG where strength is needed, TIG where finesse is needed. And every joint goes through our quality control before delivery.

Have a part to weld and not sure which process to ask for? You don’t need to know: send us the drawing and we will take care of the process.

Behind every metal frame, bracket or panel there is a process made of precision and technical choices. At LY-CO we manage that process from start to finish, from raw sheet metal to the finished part, inside our own shop. It is the way we have worked since 1964, generation after generation.

Custom light metal fabrication

We are organized as a light metal fabrication shop: we process and assemble small and medium-sized metal structures in stainless steel, aluminum and other metals. Frames, brackets, guards, panels, shelving and custom parts all come from a single supplier, with fast turnaround and consistent quality.

Laser cutting and bending

Laser cutting allows us to process aluminum up to 10 mm thick, stainless steel up to 15 mm and mild steel up to 25 mm, with clean edges and complex geometries. Bending completes the cycle: we bend the same materials up to 8 mm thick and 3,000 mm long, turning a 2D drawing into a three-dimensional component ready for assembly.

TIG and MIG welding

Our TIG and MIG welding covers all steels and aluminum alloys. This is the stage where our operators’ experience makes the difference: strong, clean joints that meet the project specifications.

Surface treatments and finishing

The cycle ends with surface treatments: sandblasting to clean and prepare surfaces, shot peening to improve strength and surface roughness, vibratory finishing for deburring and polishing parts, and laser marking for permanent codes, logos and traceability.
