Product:Monghao MG-500 Series
Monghao MG-500 series is an all-posion automatic welding machine with wireless remote controller. The intelligent welding tractor can automaticlly welding around the pipeline, and realise all posions of the pipeline welding process (vercal welding, horizontal welding,overhead welding,downward, internal welding ect...). We provide one stop soluon with intelligent welding torch, unique magnet welding tractor, automatic wire feeder, power supply and wearing parts etc... The welding process is simply controlled by the hand-held wireless remote control, which can efficiently improve the welding quality at high producon rates even under severe environmental condions and reduce labor intensity. This welding equipment and method is widely used in ship building,bridges,locomoves, steel structure,petrochemical industry and other industries, suitable for a variety of welding structures.

Monghao has cooperated with nearly 2000 projects in chemical construction, oil pipeline, gas pipe, water pipeline, heating, air conditioning, railway, power construction, ships and other industries. Based on our rich experience in these industries, the All-position Automatic Pipeline Welding Machine launched by Monghao can meet high standard requirement of industry users.
We developed a new generation of all-position automatic welding machine system "Foxcweld", greatly improve the quality of welding and easy to operate.
Our welding machine can realise six axis action, which basically meets all the action needs of manual welding method.Workplaces applicability is wide and more than Φ130 mm pipes are applicable, without welding thickness limit. After preset parameters you can press the button to start.
We also open our welding expert system database to customers so they can develop the welding process on this platform independently,preset and real-time call parameters to keep seam formation consistency.
