    Choosing the correct Welding Blanket for your application

    Choosing the correct Welding Blanket for your application

    Welding Blankets - What is the correct blanket for my application ?

     Choosing the correct welding blanket can be a challenge. With so many options on the market it can be hard to ensure you get the one which best suits your requirements and will last the distance

    Welding Blanket

    Materials

    Welding blankets in the early days were made from woven asbestos, but due to safety concerns production of these ceased. Now, safer materials are used, with blankets using materials such as fibreglass and silica as base materials which can then be coated.

    Fibreglass is an ideal material to use for a welding blanket as it has a high melting temperature, as well as being strong and durable. However, if they are not coated, they can shed fibres and irritate the skin.

    Silica welding blankets can withstand the highest temperatures, as the heat resistant fabric is premium quality and is also environmentally friendly and non-hazardous.

    Coatings

    There are a number of different coatings which are used on welding blankets. These determine the use of the blanket and the estimated peak temperature.

    Heat Treated – This causes the fibreglass to shed less and increases the level of heat resistance provided.

    Vermiculite – Used on Silica blankets to provide a mineral based finish to improve its abrasive resistance and helps prevent fraying.

    HT – In-organic coating which increases the anti-slip properties and the heat resistance.

    PU – Specially formulated fire-retardant PU-coating with aluminium pigments to increase the anti-slip properties and resistance to fraying.

    Alu-foil - The foil is applied to the fabric (heat resistant bonding agent) and gives the fabric a high heat radiation reflection. These blankets are suitable for protection against radiation heat. The foil with which the fabric is coated is resistant to abrasion and cracks.

    Neoprene – Fully cured flame-retardant black neoprene rubber which helps to protect against oil, grease and acid.

    Silicone - Silicone rubber which has high resistance to extreme mechanical, thermal and electric influence.

    Temperature

    It’s important to consider the recommended peak temperature when buying a blanket as the temperature will depend on your process being carried out and the materials being used.

    Thickness

    The thickness of the blanket should depend on the process and the level of protection you require. It’s important to ensure you buy a thicker blanket if you intend to use it multiple times. Blankets can also be folded to give multiple layers of protection.

    Proline Welding Blankets

    Proline offers an extensive range of welding blankets to provide protection from sparks and welding splatter. Blankets have been tested according to specifications of the highes of standards EN 13501-1 and do not contain any asbestos or ceramic fibres. Proline recommends using multiple layers and to use the blanket at an angle to the welding arc, as this provides the best protection.

    When using any welding blanket, please remember that they are consumable items. If you have continual use for a blanket its important to buy a higher quality, thicker blanket which will last longer and give a better level of protection and value in the long run.
