Conventional and Controlled Short Circuit GMAW Processes for Downhill Pipe Welding


Researchers show that derivative GMAW processes with waveform control power sources are capable of achieving sound welds according to API 1104 even if misalignments are present. These derivatives include Fronius’ Cold Metal Transfer (CMT®), Miller’s Regulated Metal Deposition (RMD®), and Lincoln’s Surface tension Transfer (STT®).
