01

TIG Welding

Tungsten Inert Gas

Arc welding process with a non-consumable tungsten electrode under inert gas shielding. Ideal for stainless steels, aluminium and special alloys. Exceptional precision and quality results.

02

MIG/MAG Welding

Metal Inert/Active Gas

Semi-automatic continuous wire welding under gas shielding. High productivity for standard and stainless steels. Suited to large series and metal structures.

03

Orbital Welding

Automated 360°

Automated orbital welding for high-precision piping. Guarantees consistent and reproducible quality around the full tube circumference. Pharmaceutical and food-grade standard.

04

Arc Welding

Coated electrode

Classic and versatile process for heavy metal construction work. Usable in all positions and on all types of steel. Proven robustness and reliability.

05

Plasma Welding

Concentrated plasma arc

Advanced technology using a concentrated plasma arc for high-quality welds on thin materials. Surgical precision and low heat input.

06

Quality Control

Tests & Certifications

Systematic non-destructive testing (NDT): radiography, ultrasonics, penetrant testing. EN ISO 3834 certification, welder qualification per EN 287/ISO 9606.
