  • 01. Introduction of DWG-3000 full auto mesh welding machine
  • With the high-speed development of construction industry and the application of new technology, steel bar welded mesh, as a new type, high efficiency, energy saving, reinforced concrete structure building material, has been architecture widely recognized. It has increased the strength of structure, steel saving, labour saving and convenient transportation and construction, high dimensional accuracy, easy to specialization, large-scale production, high comprehensive economic benefits etc. Many countries have made the corresponding regulations and standardsto expand promotion of welded steel fabric in various fields, now the welded steel fabric has been widely and mainly used in construction, industrial and civil construction concrete; transportation: high-speed railways, highways, tunnels, bridges, airports; water conservancy, port, electricity, and warehouse facilities; environmental protection facilities, entertainment; coal industry, animal husbandry, forestry, husbandry, etc.
    DWG - 3000 mesh welding machine (as shown in figure 1) absorbs foreign advanced experience, on the basis of advanced technology and combined with domestic actual production requirement. The machine can weld hot rolled ribbed steel bar, cold rolled ribbed steel bar, round ribbed steel bar, light round for high quality cold drawn steel cross welding, large output, high precision, easy modification, operation, low failure rate, energy-saving, low consumption and high quality. The features is as following:
    It’s pneumatic welding, servo drive and PLC controled, the mesh width, mesh opening can be stepless adjusted accurately.
    Set welding parameter on the touch screen to be easier for adjust.
    There are buttons and switches on the operatiob panel, you can choose the welding method and control the movement
    Welding wire diameter: 1.7-3.5mm
    Mesh width: 3000mm
    Mesh size: 50-200mm, can be adjusted
    The electrode can be move, welding speed is 40 strokes/min
    To promise good welding quality, the welding current, welding time, welding pressure, etc can be adjusted according to the material.
    Key transmision part, working part, electric part, penumatic part are apply international brand, can support long service life and high accuracy.
    Welding transformer, electrode, secondary wire and main circuit of SCR control system are water cooled.
    According to the power supply, you can choose one-time welding or 3-time welding.
    There is less spark and low noise in the welding proceed.
    Easy operatiob and maintain.
    Match with basement, easy for installation
