Solid State High Frequency Welders

By on

Tubos Colmena, Colombia’s leader in the manufacture of structural and mechanical tube and pipe products, has invested in two Thermatool Solid State High Frequency Welders to improve operational performance and to reduce operating costs because of improved electrical efficiency: the advanced HAZControl Technology 300 kW HF Welder with selectable variable frequency and the single cabinet Compact 150 kW HF Welder.

 

The HAZControl Technology 300 kW HF Welder will enable Tubos Colmena to get precise weld heat input control and store and recall tube welding recipes. This feature offers consistently optimized process parameters, such as Power (Heat), Frequency (Heat Affected Zone Width), Vee Length and Mill Speed, to deliver uniform and repeatable weld characteristics.

 

HAZControl Technology allows tube and pipe producers to tailor their products to the exact specifications required by their customers. Precise weld heat input is the new global standard for HF Welding.

 

The Compact 150 kW HF Welder, equipped with Electronic Load Matching, was perfect for retrofitting and upgrading the second mill where the Thermatool vacuum tube welder had been in operation for over 40 years, according to the company. The compact welder is one of the most cost-effective upgrades available with a small footprint, fast installation and commissioning.

 

Nicholas Gomez, Lines Production Manager at Tubos Colmena, noted that “the increase in mill productivity was immediate. Not only did this installation increase mill speed and reduce weld power, but also electrical efficiency has improved by over 20%. We are running faster and more reliably than ever before, with consistent and repeatable, precision welds. We were able to increase our speed from 45 MPM (meters per minute) at 5 MTPH (metric tons per hour) to 75 MPM at 8 MTPH.”

 

Victor Monreale, Latin American sales manager for Thermatool, said, “Thermatool and Colmena have been working together for over 50 years transitioning from the old vacuum tube HF welding technology to our current solid-state HF induction welding technology. Thermatool maintains a strong Latin American presence as we continue to support all of our local customers in Central and South America.”
