Shanghai Zhengzhuo Machinery Manufacturing Co., Ltd.  

Product Name: Tube to Tube Welding Machine Electric Current: Pulse Control: Automatic Cooling Way: Water Cooling Application: Boiler Origin: China Product Description As commonly seen with superheaters, economizers, reheaters and others are made up of long lengths of tubes. The tube to tube welding machine facilitates the joining of tubes by gas tungsten arc welding (GTAW)or gas metal arc welding (GMAW)or both. Our equipment meets the stringent requirement of the boiler manufacturing industry.Take away the methods of yesterday whereby lengths of tubes or elbows are joint manually. The tube to tube welding machine is a high efficiency, quality and consistencyproduction equipment. The secret lies in the combinations of the pulsed TIG method, hot wire system, AVC and proprietary program developed by us.1) Hot wire systemThe system produces a true sine-wave output, resulting in a stable and consistent welding arc. The AC waveform ensures no magnetic effect with the DC welding arc. It's benefits:High deposition rateHigh welding speedLow risk of lack of fusionHighly suitable for narrow-gap welding and surfacing2) Arc Voltage Control (AVC)TIG arc as a sensor for gathering distance information. The arc voltage and positionadjustment to keep the torch height above the melt poolby compensation of the deviations in arc voltage with regard to the reference value using mechanical height adjustment.3) ProgramOur proprietary program had undergone many evolutions and improvements. Today, it allows for an extensive setting of parameters at various instances that would correct undesirable moments in weld formation.Overview of SpecificationsTube Diameter28-76mmWall Thickness1.5-20mmWire SizeΦ0.8,Φ1.0mmOscillation Range / Speed0-20mm / 0-120mm/sWire heater5-100AScan the code to watch Youtube video
