Tig welding - Import export

The core of the Rotoweld technology is its unique vision-based penetration control system. It enables any operator to perform high-quality girth welds after just a few hours of training. Like the welder’s eyes and hands, the system continuously analyzes the image of the root weld pool picked up by a video camera integrated into the welding arm. Unique algorithms use this information to adjust welding parameters, such as travel speed, wire feed rate, arc voltage, or weaving width. This constantly adapts the process to varying conditions, such as changes in the gap, alignment, root face, or temperature. The computer’s fast reaction time means the machine can work at high deposition rates and travel speeds at which weld pool conditions are too critical to be sustained by hand.

Our company specializes in a wide range of welding services, with an emphasis on high quality welding welds. We use modern technologies that guarantee excellent results. We carry out welding of a variety of materials, including carbon/structural steel, stainless steel and aluminum. Our production facility meets stringent quality standards, such as PN-EN ISO 3834-2:2007 and PN-EN 1090-2:2018-09. We have implemented modern welding technology for group 1.1 and 1.2 carbon steels in accordance with PN-EN ISO 15614-1:2017-08. Our skills include working with steels such as S355J2 and steels with lower yield strengths, especially for material thicknesses above 3 mm for fillet welds (3-23 for butt welds), welded using the MAG-135 method. We provide professional execution of any steel welding service.

In our production plant, we have implemented the technology of welding carbon steels from material groups 1.1 and 1.2. These are S355 J2 steels and steels with lower yield strengths. Range of thickness of welded materials: Butt welds are implemented for steel with a thickness of 3 - 24 mm Fillet welds are implemented for steel> 3 mm thick The welding method is MAG - 135, i.e. solid wire welding.We also weld stainless steel using the TIG method. We have ISO 3834-2 and ISO EN 1090 certificate. We weld steel elements and light steel structures, also in serial quantities.

Tungsten inert gas (TIG) welding offers many advantages over other fusion welding methods, such as the complete absence of spatter and low welding-fume emissions. Since TIG welding uses a non-consumable electrode, the process is ideal for welding so-called root passes or in forced positions due to the decoupling of current and welding consumables.
