How to choose between the different types of welding blankets?

What you should take into account when choosing a flame retardant blanket for welding jobs?

Why there are different classes of welding blankets in the market? Simply because welding techniques are different, there are ligh welding and other stronger and on the basis of this, projection will be weaker or stronger, in this way blankets are chosen according to the type of welding to be performed.

What similarities and difference these flame retardant blankets have?

The most used material in welding blanket’s confection is flame retardant fiberglass fabric, due to its isolating, high temperatures resistance, hean and displacement features.

Fiberglass is reached by filtering melted glass through a piece with very thin holes and when glass cools down, the obtained material is flexible enough to be used as fiber. Starting from this raw material different types of fabrics are created, very resistant to high temperatures than when mixed with other materials, composed by minerals or simply covering the fiberglass fabric with them, it makes it gain features much more resistant.

The difference consists in its composition basis. In the market welding blankets could be found with silicate, polyuretane, vermiculite, aluminium paper, grafite, clay, among other coverings that bring technical features to the fabric according to which the blanket could be used for vertical or horizontal applications, by one side or both, to protect us from high or low intensity welding jobs or for cutting techniques, and could have a higher capacity as thermal or electric insulator.

Also, there are other special flame retardant blankets for welding use that are used in pieces’ cooling processes, molds or welded objects, its function is controlling that temperature descends in a progressive way, this is the case of thermal blankets.

What other aspects should we consider to choose a welding blanket?

Working temperature, type of metal fusion with we will be working at (stain, iron, copper or aluminium, metal aloys, etc.), the splash type and level that the performed welding technique causes and the reaching of the projection are the principal elements to take into account when choosing the correct blanket.

Texfire makes available a flame retardant range for welding protection, that include flame retardant fabrics as well as flame retardant blankets, both designed to protect not only from splash and spark projections but also from heat and fire, in addition they could be used in both sides and positions, vertically and horizontally, they also offer, in addition to the fabric’s comfortability, a high safety and protection by meeting regulation  ISO 9185 (splashes of big masses of melted metal) and EN ISO 11611. (welding and during connected techniques).
