*Temperature resistance is indicative only and can vary depending on usage conditions. A safety margin should be allowed for, especially in critical applications. Blankets are not indestructable and will wear and degrade from use over time. If protecting critical or costly surfaces / items, always use more layers initially and test on a non-critical surface first. As applications and usage conditions vary widely, no warranty or fitness for use in any specific application is implied or intended.

What is a Welding Blanket?

A welding blanket is a protective tool used in welding processes to safeguard surroundings from sparks, slag, and spatter. Typically made from fire-resistant materials like fiberglass or silica, these blankets form a barrier that can withstand high temperatures, preventing heat damage to nearby objects or materials. They're especially crucial in confined spaces or when welding near other objects and equipment, providing a reliable shield against potential damage, fire, or burns. Additionally, welding blankets can come in various sizes and thicknesses to suit different welding applications, making them versatile and essential safety equipment in welding environments.

What is a Welding Drape?

The terms welding blanket and welding drape are often used interchangeably, and in many applications the type of fabric used is, and can be, the same for both applications.

Technically, a welding drape is a specialized protective covering used during welding operations to shield specific areas or pieces of equipment from sparks, heat, and debris. Where welding blankets are often used to provide broad-area protection, welding drapes are designed for targeted coverage, such as protecting vertical or overhead surfaces, machinery, or equipment from welding hazards. They are typically made from similar fire-resistant materials as welding blankets, such as fiberglass or silica, but are tailored for hanging or draping over specific areas that require protection. Ideally, the fabric used for welding drapes should have a smoother surface to allow sparks etc to slide or cascade off.

How should welding blankets be used?

Best practice for use of welding drapes and blankets will vary depending on the application, however following is a general guide:

If protecting critical or costly surfaces / items, allways use more layers initially, and test on a non-critical surface first
When using for surface protection: If possible use on an incline of at least 15 degrees, or when neccessary to use in horizontal position add more layers
Where the blanket is in closer proximity to the source of sparks etc, consider adding more layers of blanket/fabric as the sparks/spatter will have less time to cool and will be at a higher temperature at the point of touching/impact with the blanket
Use hand, eye and respiratory protection during handling and use, to protect against airborn fibres and any dust/debris that has fallen on the blanket during use
Worn or damaged blankets will compromise protection and should be replaced

Can a fire blanket be used for welding?

While both fire blankets and welding blankets are designed to withstand high temperatures and provide thermal protection, they serve different purposes and have distinct features that make them suitable for specific applications.

Welding blankets are typically heavier and thicker than fire blankets, with higher temperature resistance, to resist penetration from sparks and welding spatter during ongoing use - whereas fire blankets are typically lighter and more compact for emergency use, and designed to smother and quickly extinguish flames.

While a fire blanket may offer some degree of very light-duty protection in a welding environment, it is not specifically designed for this purpose and may not provide adequate coverage or durability compared to a dedicated welding blanket. It's always best to use equipment and materials that are specifically designed and rated for the task at hand to ensure optimal safety and protection.

How Welding Blankets are Used for Heat Treatment and Heat Retention

Welding blankets are not only essential for protection during welding but also play a crucial role in heat treatment and controlled cooling processes, also known as stress-relief. Made from heat-resistant materials such as fiberglass or silica, these blankets are used to cover and wrap around metal parts during heat treatment to retain heat, ensuring uniform temperature distribution. This helps in achieving the desired metallurgical properties by preventing rapid cooling and reducing thermal gradients, which can lead to warping or cracking. Additionally, welding blankets facilitate controlled cooling by gradually reducing the temperature, thereby minimizing internal stresses and enhancing the structural integrity of the treated metals. Their versatility in managing heat makes them invaluable in various industrial applications beyond welding.

Care has to be taken in selection of suitable blankets for this application, especially if the blanket has a coating as some coatings give off gases when in contact with heat that can contaminate the surface being treated, and depending on the coating used these fumes are often hazardous / toxic. Most Weldclass blankets are suitable for use in this application & give off very little or no gases/fumes, see above chart for more details.

What is welding blanket made of?

Welding blankets are made from different types of fabric, which offer different levels of temperature resistance, different price levels, and particular attributes and advantages. Following are the basic materials that most welding blankets are typically made from:

Material	Some Advantages	Some Disadvantages / Further Comments	Weldclass Blanket Examples
Cowhide Leather	High density, resists spark penetration Non-irritant Economical Relatively strong	Relatively low temperature resistance (typically 200^oc max) Can absorb oils and solvents, which can then become a fire hazard	PROMAX Leather
Glass Fibre (Fibreglass)	Typical temperature resistance of up to 500^oc, may be capable of higher temperature if specially treated or coated Strong and chemical resistant Economical	Can shed fibres / dust which is irritating and uncomfortable to handle Being a woven fabric, sparks can penetrate the blanket after some wear & tear Coatings can reduce irritation & improve durability, however some coatings have lower temperature resistance than the fabric, and can burn and give off undesirable or even toxic fumes	PROMAX WB550 PROMAX WB1000
Silica Glass	High temperature resistance of up to 1100^oc Softer and more flexible than fibreglass, more comfortable to handle Very low thermal conductivity, makes it particularly effective for applications that require maintaining consistent temperatures and preventing heat loss or gain.	While more comfortable than fibreglass can still shed fibres / dust Not as strong as fibreglass Being a woven fabric, sparks can penetrate the blanket after some wear & tear Coatings can reduce irritation & improve durability, however some coatings have lower temperature resistance than the fabric, and can burn and give off undesirable or even toxic fumes	PROMAX WB1100
Carbon Fibre / Felt	High temperature resistance of up to 1000^oc & more Soft, flexible and non-irritant Relatively lightweight	Very porous fabric, readily absorbs oils and solvents, which can then become a fire hazard Less resistant to chemicals etc vs fibreglass Higher cost than fibreglass, especially when used in volume or larger sizes Not recommended for heat-treatment / stress-relief	Not currently offered by Weldclass
Bespoke Materials	Attributes vary from product to product One example is Weldclass PLATINUM WB1250+ welding blanket which offers new levels of safety & protection

Welding Blanket Demonstration Video

The following video is a demonstration featuring the PLATINUM WB1250+ welding blanket. Using an oxy cutting machine to cut 10mm steel plate, the blanket was exposed to heavy sparks and molten slag. All sparks etc were retained by the blanket, and the blanket fabric was not penetrated.
