LVD Hydraulic Shears Devices manufactured in Belgium on CNC Basis , are capable of cutting steel sheets of 3 m and 6 m with the thickness of 6 to 13 mm in high level of accuracy and without creation of any pleat on the cutting edges , and by application of the templates existing in this device , the cutting data will enter into CNC Instrument and the sheet with the maximum length of 6 m will be cut completely in the form of a set Square. By the engines of 7.5 and 18.5 kw, the cutting speed of the sheets is a noticeable speed , in the manner that in each 10 seconds , a sheet with the width of 6 m would be cut.Gates Welding Instrument : Such a welding device is capable of welding various box sections and the steel poles under the Submerged Arc Welding Method from the inside or outside.Maximum lengths of the web and flange which are capable of welding in this device , are , respectively , 1000 and 800 mm and the highest welding speed in the going route is 800 mm/minute and in the return route is 1500 mm/minute, and by leaning on the PLC existing at this device , the melted little pool will be divided completely equal and the structure will be of a high quality of welding
