ROTOCON Ground Clamps Provide Quick ROI for Rotary Tank Welding Applications

High Current Pipe Welding Ground Clamp

With over 100 years of experience in pioneering the compressor, air conditioning, refrigeration industry, Meridian Laboratory was approached by this manufacturer with challenges they faced in rotary tank welding applications. The company’s manufacturing process included using conventional brushed, rotary welding grounds.

Challenge

With over 100 years of experience in pioneering the compressor, air conditioning, refrigeration industry, Meridian Laboratory was approached by this manufacturer with challenges they faced in rotary tank welding applications. The company’s manufacturing process included using conventional brushed, rotary welding grounds.

Conventional brushed rotary grounds rely on metal on metal contacts to transfer current from the rotating to stationary portions of a machine.  While simple in design and construction, there are numerous drawbacks associated with using conventional brushed rotary welding grounds.  In fully and semi-automated rotational welding fixtures the machine relies on a fixed current setting to weld each seam.  Over time, as a brushed rotary ground wears and changes in contact resistance, this increase in contact resistance leads to higher voltage drop and poor welding penetration.  The end result is a greater amount of scrapped parts which did not meet the high-quality standards the manufacturer is known for.

Solution Ground Clamps

The company learned about Meridian Laboratory’s ROTOCON MC-Series rotary electrical grounds and the wide array of models, designs, and capabilities spanning from 250 to 10,000 amperes.  They then retrofitted their existing equipment, replacing all brushed ground clamps with maintenance-free ROTOCON rotary grounds.  After installation, the customer quickly realized the gains of consistent and level current flows while eliminating the greasing and maintenance.

Key Statistics

  • Consistent and low contact resistance provided steady stable current flow
  • 100% maintenance free and arc free design allows for uninterruptable machine output and usage
  • Fewer defective end products provides quick return on investment

    I am a plant support welding engineer and found these guys through a google search. I reached out and quickly received technical … More support with specking out the proper rotary ground and direction on making modifications on my automated rotating welding application. We were burning up bearings and replacing them every 3 months. After installing the rotary grounds, lathes have been running for close to a year with no need for calibration or bearing replacement. The payback is less than 8 months and will annually save $35K in bearings, downtime for lathe calibration and bearing greasing.
    Again, the technical support was critical and the guys are easy to work with.
