Tubos Colmena Invests in Thermatool HF Welding Technology Once Again

[December 2021] – Consorcio Metalúrgico Nacional SAS (Tubos Colmena), Colombia’s leader in the manufacture of structural and mechanical tube and pipe products since 1957, wanted to meet the growing demand from the local market and to increase productivity. Colmena invested in two Thermatool Solid State High Frequency (HF) Welders to improve operational performance, and as a bonus reduced operating costs because of improved electrical efficiency. Thermatool’s advanced HAZControlTM Technology (HCT) 300 kW HF Welder with selectable variable frequency was commissioned on July 1, 2021, and a Thermatool single cabinet Compact 150 kW HF Welder on November 27, 2021.
The HCT welder will enable Tubos Colmena to get precise weld heat input control and also 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. HAZControlTM 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 Thermatool 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. The Compact welder is one of the most cost-effective upgrades available with a small footprint, fast installation, and commissioning. Read the full press release in our next ITAtube Journal
