CBM-80 Series

Welding Back up Material

CBM - 80 Series

The CBM-80 series, the most popular product family made by VENVULAS, are widely used as a welding supplement for shipbuilding, marine plants, and any other steel constructions.

The CBM-80 series consist of aluminum adhesive tape, which is specially designed for the heat resistance, and ceramic blocks, which can resist strong heat shock.

CBM - 80 Series

The CBM-80 series can be used for most types of one-sided welding, including FCAW and GMAW.

The CBM-80 series can be applied to all welding posture (1G, 2G, 3G, 4G).

The CBM-80 series, which improved welding e�ciency remarkably, can not only shorten the working hours but also guarantee theexcellent slag removability and top quality of backside bead formation (smooth and clean).
