Fingerhuth welding blankets protect machinery, equipment, work areas and sensitive surfaces from flying sparks, welding spatter, molten metal spatter, flames and thermal radiation. Depending on the thermal and mechanical requirements, various material qualities made from glass fibre fabric, pre-oxidised fibre and high-temperature-resistant silica fabric are available. Our range extends from lightweight spark protection blankets for standard welding and grinding work to robust heavy-duty and silica welding blankets for demanding industrial hot work applications.
Our range includes welding, spark and spatter protection blankets for industrial applications. The individual grades differ in terms of temperature resistance, fabric weight, material construction and mechanical durability, enabling targeted selection for the respective application.
Temperature alone is not the only selection criterion. Spatter exposure, mechanical loads and the type of surface to be protected can significantly influence the appropriate material grade. We are happy to support you with the technical selection.
Our specialists support you in selecting the appropriate welding blanket – matched to thermal exposure, sparks and weld spatter, mechanical loads, as well as the required dimensions and configuration.
Personal advice on product, configuration and application concept.
Selecting the appropriate welding blanket depends on several technical factors. In addition to temperature resistance, spark and spatter exposure, mechanical loads, material construction and application conditions also play an important role.
Choosing the right welding blanket depends on more than just the maximum temperature. Other important factors include the type and intensity of sparks or molten metal spatter, mechanical stress, installation conditions and the surface to be protected. For standard welding and grinding work, lighter glass-fabric grades are often sufficient, while higher temperatures or intensive molten metal spatter require more robust high-temperature or silica-fabric grades.
Depending on the material and design, our welding blankets cover different temperature ranges. Our product range extends from industrial glass-fabric welding blankets for temperatures up to 600 °C and high-temperature grades for applications up to approximately 1,100 °C to SiO₂ silica fabrics for extreme thermal exposure with short-term peak temperatures of up to 1,600 °C. A distinction must always be made between continuous operating temperatures and short-term peak temperatures.
Glass fabrics are a proven and cost-effective solution for a wide range of industrial welding, spark and heat protection applications. Silica fabrics, on the other hand, have a significantly higher SiO₂ content and provide greater thermal reserves for extreme high-temperature applications. They are used when conventional glass fabrics can no longer withstand the required temperature exposure.
For intensive spatter exposure, specially designed spatter protection blankets are recommended. Key factors include the temperature, size and energy of the impacting particles, as well as the duration of exposure. Heavy, appropriately treated high-temperature or silica fabrics are particularly suitable for heavy weld spatter, slag or molten metal splashes.
Yes. For applications where glass fibres are undesirable, welding blankets made from Preox needle felt, for example, are available. These materials are soft and flexible and are particularly suitable for sensitive surfaces as well as vehicle and automotive applications.
Yes. In addition to roll goods and proven standard sizes, we also manufacture custom welding blankets and spatter protection blankets. Dimensions, edge finishing, fastening options and other fabrication details can be adapted to the respective application.
