The paper presents a new way of repairing defects that can occur in areas with low access for the operator. A modified TIG welding torch with a 300 mm neck length is used. The picture of the metal bath is taken over by a videoendoscopic camera and displayed on a screen. The welder makes the necessary corrections by handling the TIG gun remotely. Images are shown during welding. Also shown are some welding samples. After analyzing the evidence, it can be concluded that the defects founds at relatively large distances can be repaired thru welding, without the need to dismantle the facility requiring reconditioning. Taking this into consideration, the new technology it greatly reduces repair costs and runtime. The necessity of making such a pistol came in response to various industrial repair requests. Most applications were in the field of spiral heat exchangers where interventions are difficult due to reduced access space below 25 mm. Such equipment is useful in various engineering fields such as: aviation, structure, landing gear train- here are periodically inspected areas using endoscopes but cannot intervene because there is no possibility of access for the operator; thermodynamics - heat exchangers, indifferent of the type of construction, with pipes, plates or spirals; Industrial plants - pipeline; metal structures of any kind - bridges, boats, halls, buildings; automotive industry - construction or repair.
