摘要: A mobile automated pipeline welding and quality control system comprising a gas metal arc carriage weld data monitor acquisition unit. The carries torch, wire feed device for feeding consumable to the an oscillator oscillating torch motorized drive mechanism moving about weldment. controller includes digital circuitry dosed loop of drive, devices. By default, operates each at one plurality pre-programmed nominal speeds selected from mode table. is responsive oscillation speed variation signals under operator, varies within ranges which are ensure compliance with specifications. has voltage current transducers measuring torch. supplies relating All this information can be displayed recorded in monitors memory. In addition, compute display heat input into based on detected parameters. This allows operator make minute adjustments during process that falls
