Welding Blanket vs Fire Blanket: What’s the Difference?

welding blanket

Safety equipment that’s specifically designed for welders is a must-have for any welding project. Whether it’s a welding blanket or a fire blanket, these pieces of equipment will go a long way in making sure that welders don’t get splatters of molten metal everywhere in a welding process. But what is the difference between a welding blanket and a fire blanket and what are each used for?

 

What’s the difference between a Welding Blanket and a Fire Blanket?

Welding Blanket

A welding blanket protects the welder and the surrounding areas during the welding process. It consists of a layer containing expanded vermiculite, a flexible protective material, and inorganic heat-resistant fibrous material. These layers maintain the structural integrity of the blanket. However, there are different classes of welding blankets because welding techniques are different. 

 

Welding blankets can be made with various materials such as silicate, aluminum paper, polyurethane, graphite, clay, and other coverings that are preferred depending on technical features. Some welding blankets can be used for horizontal or vertical applications, or one-sided or both, to give protection for high or low-intensity welding jobs or for cutting techniques. Some blankets can also have a higher capacity such as a thermal or electric insulator.

Fire Blanket

A fire blanket is a safety device that is used to extinguish starting (incipient) fires. It is made of a sheet of fire retardant material that is placed over a fire to smother it. Most fire blankets in the kitchens and in the home are made of glass fiber and kevlar. These are folded into a quick-release contraption for easy storage. These nonflammable blankets can put a stop to fires up to 900 degrees. Fire blankets are great for emergency situations. This is because they’re designed with quick-release capabilities. 

 

For welding jobs, fire blankets are usually made from high-temperature fiberglass woven fabric. The fabric can be uncoated or coated. They provide protection from slag generated by welding or metal-cutting applications. Standard sizes include 1m x 2m or 2m x 2m. 

 

Welding Thermal Blankets vs Welding Fire Blankets

A welding thermal blanket is used by placing it in direct contact with welded material to decrease the temperature of the welded object gradually. This is done to achieve optimal welding quality. A special kind of mineral, like vermiculite, finishes the job with a higher thermal isolator degree. 

 

welding blankets

 

A welding fire blanket, on the other hand, is used to repel sparks, slags, and melted metal from welding points. They also serve as a thermal barrier against hot fragments. They could be used vertically or horizontally depending on welding contexts. 

 

Both welding blankets and fire blankets are designed to protect welders not only from splashes and sparks but also against fire and heat. Aside from that, equipment like this offers high security and protection because they meet regulations ISO 9185 for splashes from big chunks of melted metal and EN ISO 11611 for welding and other related techniques

What You Should Know About Proper Welding Blanket Upkeep

Washing Your Welding Blanket in a Washing Machine

As a general rule, when you wash your welding blanket in a washing machine, do not mix the welding blanket with other heat-resistant or non-heat-resistant clothing items. Separate the load to prevent chemicals from non-heat-resistant materials that may contaminate your welding blanket. 

 

Next, remember that heat-resistant blankets should be carefully washed with specific detergents that won’t ruin the blanket’s protective layer. The detergent should be bleach-free since bleach can tarnish the blanket’s integrity. If you are using a home laundry detergent, check the label. Just be sure it doesn’t contain any chlorine or bleach. Some examples of bleach-free detergent are Neutral ph-balanced formula, USDA Certified Bio-based product, and Fragrance-free formula.

 

Also, don’t use fabric softeners and soaps since these can destroy the structure of the welding blanket’s protective layer. These chemicals leave a flammable coating behind. 

 

When it comes to water temperature, the best temperature for washing welding blankets is 104ºF (40ºC) and less. Avoid using the hottest temperature on your washing machine. When in doubt, always check the label on the welding blanket for the preferred temperature.

 

Finally, don’t let the welding blanket soak too long in the washing machine. If you do, detergent and water can damage the blanket’s protective layer. You can also wash your welding blanket by hand. Simply dampen it to get it cleaned. Do not soak it.

Washing Leather Welding Blankets

If your welding blanket is made of leather, use saddle soap for cleaning. Saddle soap leaves no residue and has a neutral ph-balanced formula. It is also fragrance-free. 

 

To begin cleaning, take a clean damp cloth and clean the surface of the leather. Rub the fabric across the leather blanket’s surface to remove some debris and dust. After that, take a second clean cloth and apply a small amount of saddle soap. Rub that cloth gently in a clockwise motion across the surface of the leather blanket until it disappears from the leather. Once the surface is covered, take the third cloth and use this to remove saddle soap excess. 

 

Removing Stains from Your Welding Blanket

Once you see a stain, clean it at once. Common stains on welding blankets include paints, solvents, oils, and other flammable substances. Because if you don’t, these stains can reduce the blanket’s heat protection. 

 

To remove stains begin with filling your sink with hot water, then wet the welding blanket. Rub dish detergent or liquid laundry detergent on the stained spot. Let that detergent rest on the blanket for about 3 to 5 minutes. After that, rinse the detergent off and check if the stains are clean. If the stain is still there, take it to a professional cleaning service.

Welding blanket, so many different materials, sizes, functions... It's very hard to decide what type of welding blanket you actually need. If you don't want to make the wrong choice, be sure to read this entire article. We will give you information about all the different materials and its applications

If you search for a welding blanket, the first thing you will notice is that there are a lot of different materials used. Most welding blankets are made of fiberglass. But even then, there’s a wide variation of coatings. Which welding blanket do you need? And what makes a blanket the right fit for your job? In this article we will discuss the applications of a welding blanket, the different materials used, coatings and other useful details if you want to buy a welding blanket.

For what applications can I use a welding blanket?

For welding, obviously!

Welding blankets are originally made for the purpose of welding. Since it’s heat resistant, it can work as a shield to protect other material against sparks and splatter. Like the bodywork of a car, a wooden floor, a carpet, … Of course, it also comes in handy while grinding, cutting and every other activity that creates heat. When welding, it’s important to know if the blanket can be used on both vertical as horizontal surfaces. Keep in mind that welding blankets on horizontal surfaces, need to sustain a lot more heat.

But also a lot of other applications.

Since welding blankets serve as an excellent shield against heat and fire, it can also be used for many other applications. For example, a fire blanket is basically a light welding blanket and helps to prevent fires. Many people also buy a welding blanket to insulate their grill during cold weather. That way their grill keeps and stabilizes the heat longer and burns less fuel or pellets.

We also heard people using a welding blanket to protect their wood deck or lawn from a the fire pit or grill. You can even make a bonfire on a good welding blanket, the lawn underneath will be protected.

It has so many different applications, the possibilities are endless. But it’s very important to know which welding blanket you need for what purpose.

What you must know about the materials of a welding blanket.

In the past, welding blankets were made of woven asbestos. For safety reasons, this production has been stopped worldwide in the early nineties. Other, more safe materials are being used now. Usually the blankets are made of a basic material. Fiberglass blankets normally are also coated depending on the wanted features. Make sure you always choose a welding blanket that is sewn with Kevlar thread. This thread is very strong and when getting in touch with high heat, it doesn’t melt, but disintegrates. Making it more safe to use.

What are the differences in welding blanket materials?

Most welding blankets are made from fiberglass. But you can also find leather and felt blankets, each with their own characteristics.

Fiberglass welding blanket

welding blanket

Fiberglass is made of the same components to make glass. Those are mixed together, heated up and from that threads are spun. Those threads are woven and that’s how a fiberglass blanket is made. Since fiberglass has a high melting temperature, it’s an excellent tool for us. The downside is that fiberglass loses small sheds that irritates the skin. To avoid this, and to increase other features like heat resistance, fiberglass fabric gets a coating.

Pros:
  • Cheap
  • Very heat resistant
  • Strong and durable
Cons:
  • Sheds when not coated, irritates skin

The different coatings are discussed further in this article.

Leather welding blanket

leather welding blanket

Leather is a natural product that is fire resistant on its own. For that reason, many welding apparel (like welding apronswelding sleeveswelding jackets etc.) is made of leather, more specific split cow leather. Leather blankets are nicer to work with than fiberglass, but it’s also much more expensive and heavier. Normally a leather blanket doesn’t have any grommets, so they work perfectly as a cover to protect car bodies against sparks and splatter.

Pros:
  • Feels smooth on skin, no coating needed
  • Strong and durable
Cons:
  • Very expensive
  • Heavy, less useful to work with

Felt welding blanket

carbon felt blanket

Felt is a sort of textile that is not woven, but by pressing the fibers together. To make a felt welding blanket, carbon is used for the heat resistant character. Carbon felt has a temperature resistance of 1800 degrees Fahrenheit (about 1000 degrees Celsius), which is incredibly higher than fiberglass and leather. Felt also feels soft and won’t irritate your skin. The downside is that it’s not as strong as fiberglass and leather, and it won’t last as long either.

Pros:
  • Cheap
  • Resistant against very high temperatures
  • Feels soft on skin
Cons:
  • Not durable, not for using in the long term

Different fiberglass coatings, what is important to know?

There are very much different coatings, each with their own specifics. We will discuss the most used. It happens often that multiple coatings are combined, with the purpose to add multiple specifics.

Heat treated coating

The cheapest welding blankets are heat treated. With this treatment, fiberglass sheds less and has a higher heat resistance. Fire blankets are usually heat treated. This type of welding blanket is for light duty welding work. Even with the heat treatment, the fiberglass still sheds a lot and should be used wearing gloves.

Silicon and acrylic coating

Silicon and acryl are a heat resistant materials that feel soft. These characteristics make it excellent to use as a coating for fiberglass. The downside is that they are not resistant against high temperatures. They are great for light duty welding work.

Vermiculite coating

If you need a welding blanket that doesn’t irritate your skin and has a great heat resistance, vermiculite coated welding blanket could be the right choice. Vermiculite is a safe coating that increases all the wanted requirements of a welding blanket: it can resist a high temperature and it doesn’t irritate the skin. Vermiculite welding blankets are the best choice for both light as heavy duty welding.
