Fully automatic tube-to-tubesheet welding for boilers, heat exchangers, condensers and coolers. Applicable tube inner diameter 24–108 mm, with expanding heads customized to your tube size.
Also known as: tube sheet welding machine, tube-to-tubesheet welding machine, boiler tube welding machine.
Position the welding head on the tube, and the HLGB25-108 completes the tube-to-tubesheet joint automatically — consistent penetration and bead appearance across the whole tubesheet, tubesheet after tubesheet.
