T used in the domestic shipbuilding steel production, mostly single, slow, inefficient, high labor intensity, can only process a number of light and small T-shaped steel. Multi-stage gantry T beam production line can solve these problems, but such welding technology only a few in Japan and other developed countries have applied a small number of large shipbuilding enterprises in China is to buy the equipment from foreign countries (Japan exclusive monopoly), but expensive (12 million / unit), and features a single, long lead. To this end the company based on the actual conditions in the domestic industry first developed a highly efficient, high-speed, low cost, high performance platform for 24-pole steel gantry T welding production lines. The product of the PLC programmable controller and inverter to control the entire production line, and the welding speed and welding speed adjustable pre-set function, uniquely developed six T profile 24 forming a welding electrode T Steel Platform welding production lines. The line is compact, easy operation, high efficiency, saving space and personnel, is the bulk, high-speed forming a welded T sections of large equipment.
