Purpose of the development: Ukrainian Institute offers automatic welding machine for electroslag welding of vertical and inclined both straight and curved seams of metal thickness of 30 ... 100 mm. The material of the welded metal structures can serve as carbon and low alloy high strength steel, and austenitic.

Recommended application field: Repair and construction of metallurgical units (blast furnaces, converters, etc.)

Technical characteristic: The thickness of the metal being welded, mm: 30-100; the number of electrodes, NY .: 2; electrode diameter, mm: 3; welding current at each electrode at 100% duty cycle, no more, A: 1000; feed rate, m / h 0 ... 450; machine travel speed, m / h: 2-6; weight of the machine, not more, kg: 60.

Advantages over analogues: Using an automatic process of electroslag welding, which is characterized by high stability of the process, it helps to ensure a repeatable welds consistently high quality. Moreover, the lack of elevated edges training requirements, the use of conventional welding materials, high performance and cost make this method of welding the most preferable to perform long vertical joints metal thickness of 30 ... 100 mm, both in the installation and in stationary conditions.

The development stage readiness: Introduced in production

Description of the development:
()
The device consists of four modules quickly mounted without tools, using the key-ratchet, which significantly reduces set-up time of the seam. It is equipped with two feeders with a separate independent variable speed feed each of the wires. Microcontroller system control unit reliably stabilizes the supply electrodes and moving the unit for any changes loads and supply voltage fluctuations, and also makes it easy to set the required values ??of velocities and implement their control in the welding process. Control unit has a digital display welding speed (m / h) feed rate of each electrode (m / h) and the welding voltage on each electrode (B). Undercarriage unit moving along the track, in addition to the welding, can serve as a running gear for gas-oxygen torch, in the preparation of weld joints, and for devices that provide further processing of the welded joint. As a guide using a rolling steel angle section 50x50 mm.
