Welding unit UET-1

Tractor chassis TSN-4 . Using a skidding machine widely known in the Russian Federation as a base chassis allowed us to create a welding unit with high cross-country ability for use in highway conditions.

The van is insulated with a frame structure , the outside is made of welded corrugated steel sheet, the inside is lined with non-combustible material, the walls are insulated.

The van has several compartments and contains the following equipment:

• The 100 kW electric unit is installed in a separate unit compartment with the radiator close to the wall, in which an outlet window for cooling is made. Exhaust gases are discharged through the muffler.

• Welding sources (4 posts) are installed in the main compartment of the van. Welding units UET-1 (AST) are equipped (up to 4 posts) with modern welding equipment from Lincoln Electric (USA), which allows combining various types of welding (automated wire welding, various methods of semi-automatic welding, stick electrode welding) into a single technological process.

• Remote equipment , in particular LN-23P/LN-27 wire feed units, welding cables and grounding cables, pipe cutters, cutting torches with hoses, windings for demagnetizing pipe joints, spotlights, remote controls with cables, etc. are stored in separate compartments with access from outside the van. When working with remote equipment at a distance of up to 30 m, the passage of cables and hoses from the compartments is ensured with the doors closed.

• The crane-manipulator unit (KMU) for carrying out cargo handling operations is mounted on the vehicle chassis between the cabin and the van. It has mechanized movement in the horizontal and vertical planes. Usually, a hydraulic manipulator with a lifting capacity of 750-1000 kg at a reach of 5.5-7.1 m with a hook suspension is used as a KMU . The hydraulic system of the manipulator is activated from the hydraulic system of the tractor. The manipulator is controlled from the tractor cabin. The axis of horizontal rotation of the manipulator coincides with the longitudinal plane of the chassis. In the transport position, the manipulator rests on the front pillar in front of the cabin. At the customer's request, other types of manipulators and a different arrangement on the chassis can be used.

• The welding tent or shelter in a folded state is placed on the roof of the van, where access is provided from the ground and the crane suspension of the KMU.

• High-pressure cylinders are installed in an open area, where the crane suspension of the KMU is accessible, or there is the possibility of installing and replacing them manually.

At the customer’s request, it is possible to place equipment required for work on main pipelines, as well as other welding equipment.
