- Submerged arc: Banda, Hilo - Plasma welding and clading - Semi-automatic (MIG / MAG Pressed) - Automatic MIG with or without oscillation - TIG pressed - Automatic TIG with or without hot wire - Manual arc - TIG tube-plaque Using the automatic TIG and MIG/MAG processes, Atecsol can make interior claddings of tubes, tubes and tubesheets of different diametres and lengths depending on the process: - Automatic MIG: Interior cladding of tubes and tubes with a length of 6 m., with diameters superior to 250 mm., making the contribution in spiral and oscillating avoiding as a result the accumulation of tensions in the same generatrix improving thus the quality of the job. VIDEO - Automatic TIG: Interior cladding of tubes and tubuladuras from 1 ½ inches and 1 m. length, increasing the length depending of the enlargement of the diameter.  For this process we count with TIG premises equipped with AVC system (control of the arc voltage and the contribution material) and the possibility of high precision axial and circular movement. Thus, we can achieve high quality tasks. The applications described solve with guarantees the necessities that quite often arise in the petroleum derived products industry (reactors, exchangers, etc.) Atecsol has developed an own plasma welding system which allows us to weld sheet metals up to 5 mm width with a single pass. This type of welding is requested by the nuclear industry, in particular for the nuclear waste storage equipments.
