Department of General Problems of Arc Welding Techniques and Technology

The weld can be:
Rectilinear, curvilinear, inclined, vertical.

Carbon, low-alloy, austenitic and other types of steels are suitable for welding.

Design and operation

The design of the AD-381Sh welding machine provides quick assembly into a work condition (disassembly into a storage and transport condition). The machine is equipped with 2 feeding mechanisms with separate adjustment of the wire feed rate.

The stability of this parameter is monitored and maintained by a microprocessor system that also controls other operating parameters, such as the machine’s speed. Due to this software implementation, the stability of the set parameters of the operating mode is achieved, regardless of such factors as fluctuations in the amplitude of the supply voltage and changes in the load during movement.

The control unit is equipped with a digital display that shows the following parameters: welding speed, speed of movement of both electrodes, voltage on both electrodes.

The machine provides stable quality repeatability of the weld.

Brief technical description of the AD-381Sh welding machine

The new generation AD-381Sh machine for electroslag welding was designed at the E.O. Paton Electric Welding Institute of the NAS of Ukraine. Staff colleagues of the Institute provide engineering support, testing and customization of welding equipment.

The AD-381Sh welding machine is designed for automatic electroslag welding of both plumb and inclined rectilinear and curvilinear welds of metal with a thickness of 30…100 mm. The material of welded metal structures can be carbon and low-alloy steels of increased strength, as well as austenitic.

Technical specifications:

Metal thickness, 30…100 mm
Quantity of electrodes, 2 pcs
Electrode diameter, 3 mm
Welding current per electrode at 100% DC, not more than 1000 A. Electrode feeding rate, 0…450 m/h
Machine movement speed, 2…6 m/h
Weight of the machine, not more than 60 kg

The AD-381Sh is equipped with two feeding mechanisms with separate independent adjustment of the feeding rate of each wire. The microcontroller control system of the machine reliably stabilises the electrode feed and movement of the machine under any changes in load and fluctuations in the supply voltage, and also makes it easy to set the required speeds and control them during welding. The control unit is equipped with digital indicators of welding speed (m/h), feed rate of each electrode (m/h) and welding voltage on each electrode (V). The AD-381Sh is successfully used by Arcelor Mittal specialists in the repair and construction of metallurgical units. In particular, the use of this machine allowed for the successful repair of the housing of the Europe’s largest blast furnace No.9. These machines have been successfully used in the construction and repair of all blast furnace housings and converters at ArcelorMittal. At Yenakiieve Iron and Steel Works, AD-381Sh was used for electroslag welding of all plumb welds of the housing during the construction of the blast furnace No. 5, which amounted to 120 running metres or 20% of the total length of all the welds of the blast furnace housing. OJSC Baltic Shipyard put into operation the AD-381Sh machine for making longitudinal rectilinear welds of metal structures made of 08Kh18N10T steel with thicknesses of 40…50 mm. The use of automatic electroslag welding, which is characterised by high process stability, promotes producing welded joints of consistently high quality. The absence of increased requirements for edge preparation, the possibility of using standard welding consumables, high efficiency and cost-effectiveness make this welding method the most preferable in producing longitudinal vertical butt welds of metal with a thickness of 30…100 mm both during assembly and in stationary conditions. The proposed machine is unique.
