As a welder, your knees can be especially vulnerable. You may have to kneel to get in a good position to make the weld, or you may be working where there’s lots of scrap or junk.

Welders need to protect their body from exposure to sharp metal edges, jagged surfaces, red hot metal, sparks and other hot flying metal or else risk consistent bodily harm.

There’s also external surface materials like rocks, uneven concrete or gravel that can puncture knees or lower legs to worry about. With all of these factors you definitely need some of the best welding kneepads.

Kneepads come in two varieties: built-in kneepads and strap-on kneepads. Both types are used by many welding professionals and each type has its pros and cons.

Best Welder Knee Pads


The Good

You can perform for hours in these kneepads from KP Industries because they are so comfortable.

Made with a tough, hard plastic outer shell, they also have flexibility due to the hinged joints which allow you to move with ease. The outer shell is chemical-resistant and can withstand extreme temperatures, making it perfect for this line of work.

The built-in pad is ½” thick, and made of closed-cell foam so the pads are super comfortable and protect the knees from impact. The pads are sweat and water repellant, which helps keep them cleaner longer.

Soft elastic woven straps above and below the knee strap easily strap into place behind the knee with a speed clip that slides into place and stays secure. They don’t ride up or slide down and will not bind the knee.

The Bad

While the plastic outer shell on these kneepads is flexible, it won’t tolerate big adjustments, so these may not be the best choice for people with large legs. You'll also have to make sure you get the right size, as if it's not a good fit they won't be nearly as comfortable.

Additionally, you will want to wear these pads over pants as the hard, plastic outer shell could chafe, pinch or scratch bare skin. The KP Industries Ultra Flex kneepad will provide you comfort, protection and durability. These kneepads come in a range of colors: black, green, tan and gray.

The Good

The Good

True Flex kneepads provide durable protection and can be used in some of the most extreme working environments on the planet. They are made from a hard plastic outer shell that is designed to flex with the natural motion of the knee, using a hinged joint.

The interior of the shell contains a dense, comfortable foam pad with an air vent system that allows the knee to breathe. Shock-absorbing grip strips protect the kneecap from extreme physical jolts.

The Bad

Only bad thing about this knee pads is the relatively weak return and warranty policy. You may return within 30 days of delivery for a full refund so be sure to test the pads extensively in that period.

Final Thoughts

Adjustable Nylon elastic straps above and below the knee keep the kneepads securely in place and do not bind the knee. The TSE True Flex kneepad should provide you maximum comfort, protection and durability and are a good alternative to the #1 rated Ultra Flex III. These kneepads come in blue with black grip strips.

Best Built In Kneepad

Kneepads that are built in are either permanently sewn into a pair of pants or inserted into a pocket that is sewn into the pants that you will be wearing while you work. They are typically lighter weight than  strap on knee-pads and are less bulky. If you want something heavy duty go with one of the choices above instead of the products below.


The Good

Caterpillar doesn’t just make construction equipment - they also make a line of rugged work wear.

The Caterpillar CAT work pant is a heavy-duty work pant made out of abrasion-resistant cotton/polyester canvas material with reinforced stitching.

Despite the fact that they can handle heavy duty work, they are amazingly lightweight. The waistband has gripper tape to keep shirts and pants in place. There are also side waistband tool holders and lots of pockets.

The Bad

The knees are double-layered with pockets with foam kneepads. While the price is right, the standard foam kneepads are not the most durable.

Final Thoughts

These pants have double knees made of some cordura-like material that actually stands up to the rigors of contractor's daily routine, and though after a while there can be  a couple of small cuts in them, they are nowhere near wearing through after a year or two of solid use, making them still a decent buy.


The Good

Why Would You Need To Use Kneepads When Welding?

In welding there are many situations that require you to kneel in order to get the right weld, cut on a piece of metal or part.

This can be extremely taxing on the joints. Stress applied to the patella and the patella tendon after extended periods of kneeling can result in knee-specific injuries.

Many automotive welders spend a great deal of time on their knees welding parts in various places of the car where it’s just not feasible to weld standing up.

This type of welding requires flexibility as you may be standing part of the time and then kneeling the other part of the job. A kneepad that is flexible and will not bind, slip or prevent motion, yet protects while kneeling, is required for this type of welding.

Welding Knee Pads

Additionally, some welders work in outdoor environments where they kneel for long periods on hard, rough, wet or cold surfaces.

Outdoor work sites can have rocks, glass and other objects that can damage the knee. A kneepad with a hard, protective outer area that is also flexible and allows motion is what is needed in this type of welding environment

During welding and cutting operations, having the best welding kneepads for the job enhances your welding speed, ability and safety. kneepads can protect your knees from pain, while also providing insulation, knee cap protection and comfort.

Two Options: Pants With Built-in Kneepads Or Strap-on Kneepads

Kneepads come in two varieties: built-in kneepads and strap-on kneepads.

Both types are used by many welding professionals and each type has its pros and cons.

Built-in kneepads

Built In Knee Pads


kneepads built into work pants or jeans are very convenient. You don’t have to worry about whether you forgot to bring your kneepads to the job and you don’t have to take so much time to put them on or take them off. With built-in kneepads, you don’t have to worry about them sliding out of position, as they stay right in the pocket around the knee.


Some people complain that the pants with built-in kneepads can get hot and are heavier than normal work pants. Another drawback is that they cannot be easily transferred to other clothing.

Strap-on Kneepads

Welding Knee Pads

Kneepads that strap on are flexible or hard materials shaped like a knee that can be strapped on around the outside of the pants you would wear to work.


Kneepads that are strapped on offer the ability to be transferred from one pair of pants to another.

They can be used when you need them and taken off when you don’t. Another very desirable feature is the ability to adjust the straps to fit your leg size and to place them right where you want them on the knee.


Some kneepads that strap on have been known to shift a lot or ride up or slide down requiring frequent adjustment throughout the day.

They can become too loose or too tight and, depending on the type of straps, can bind around the crease of the knee and cut off circulation.

How To Make Your Own Pants With Knee Pads

You can also make your work more comfortable by creating your own built in knee pad pants.

  • Buy “Soft Knees” welding pads. These pads have no knee strap and are deeply cushioned. They’re very flexible and can be rolled up or squished into the position that you want them in. They are ideal for use in Double knee jeans or work pants because they do not weigh much and can be inserted and removed easily in the pant.
  • Buy Carhartt, Dickies or some other brand of Double knee front pants. These are great work pants made of 12-ounce heavyweight cotton duck. They fit loose naturally and are roomy enough to allow you to put knee pads in them. These pants already have a reinforced panel at the knees which will make it easier to insert the knee pads.
  • Simply Roll up the knee pads and insert them down into the knee pockets in your pants. Make sure you roll the pads very tightly so they will fit into the knee pocket space in the pants.
  • Once inserted, tug and wrestle with the pad until it becomes unrolled and is laying flat in your pants. You don’t have to worry about the knee pads falling out because they sit very snugly in the knee pad pockets.
  • You now have knee pads built into your pants.


Knee pain is a common complaint of trade professionals in the construction and welding trades. Whether you are looking for kneepads for indoor or outdoor welding jobs, there are a variety of choices.

Built-in kneepads offer the convenience of not having to put on and take off or constantly adjust the knee pads but they do make the pants heavier and hotter to wear. Strap-on kneepads give the option of only putting them on when you need them but they can ride up or slide down and require adjustment to use.

When choosing the proper kneepad for the job, you should review the different types, paying close attention to the following: durability of the material for prolonged use, impact resistance, and affordability.

Proper knee protection will make a day’s work more comfortable and prevent long-term knee damage.
