Welding Services

At KOJA, we provide professional welding and spot-welding services, backed by years of expertise and advanced technology. Our modern welding facility is equipped with 25 welding stations and 4 spot-welding stations, operated by a highly skilled team of certified welders. Our specialists hold welding certifications from the Welding Institute for methods 135 (MAG) and 141 (TIG).

To deliver maximum precision and efficiency, we also operate two robotic welding stations powered by state-of-the-art KUKA robots from Germany — including a conventional robot with dual rotary tables and an overhead robotic welding system.

With our extensive experience, we are capable of producing even the most complex components. We design and manufacture our own welding fixtures, enabling us to handle both one-off custom projects and large-scale production runs with equal excellence.

In addition, KOJA specializes in the fabrication of steel structures. We manufacture according to client documentation, and all structural elements are protected against corrosion. Our steel constructions are widely used in industrial halls, warehouses, shelters, livestock facilities, and more.

We specialize in welding:

✔ Carbon steel

✔ Stainless steel

✔ Aluminum
