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.

SolutionGround 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 contacted Meridian Laboratory to obtain a slip ring for my Undergraduate Senior Capstone project. The project required … More a slip ring capable of highspeed data transfer with very little noise to drive an LED bar on a fan to generate images. Sven Krause was very knowledgeable and responsive and helped me figure out what product I needed. He even managed to get the slip ring donated to our team and had great advice on how to integrate it into our project. The project was a huge success thanks to Meridian Laboratory.

    I found Meridian's polyurethane ML6 fit and finish to be superior to other rollers we had sourced in the past. The tolerances … More were very tight and eliminated a lot of the jamming issues we were experiencing from the OEM's parts.

    I searched for a proper rotary ground and never found anything that was high quality, priced right and reasonably sized until … More I found Meridian Laboratory. Adam from technical sales guided me through options and quickly zeroed into a solution that was perfect for us.
    Communications were great for payment and shipping and the unit arrived as promised.
    What I received it, it was like a jewel. High quality, perfect size and installed in minutes. The ground works flawlessly at any rotation.
    I highly recommend Meridian Laboratory. We were able to install the rotary ground and simply forget it. It works that well.
