How Thick Should a Welding Table Top Be? The Best of 2022

One of the most important things you will need in your welding workshop or garage is a reliable welding table. A sturdy and reliable table with the right thickness is very important to make your job safe and easy.

In general, a welding table top should be 3/8th inch thick. Some welders may prefer thinner tabletops of about 1/4th inch thick. Anything thinner than 1/4th inch could cause the tabletop to warp due to the high welding heat. Welding tables should always be thick and strong to support heavy loads and handle the high heat generated during welding.

In this guide, we cover:

  • Why are welding tables so thick?
  • Why do welding tables have holes in them?
  • Best welding tables on the market.

Why are Welding Tables So Thick?

Every welder needs to invest in a sturdy and reliable welding table. It is one of the first investments they need to make. Whether you’re making your own tables or buying the pre-made ones, it is important to ensure it is nice and thick.

Welding tables have to be thick to support the heavy items you weld. Many welders also hammer their projects on the table. That’s why a welding table needs to be thick – so it can handle the high heat and the heavy wear and tear involved in the process. 

Thin tables can easily warp due to the high heat generated during welding so you may want to choose a table anywhere between ¼ inch to 3-inches in thickness

What thickness should you opt for?

The choice of welding table thickness will entirely depend on the kind of welding you do. If you do a lot of heavy-duty welding, it is best not to go for anything less than 2-inches. This is the only way to ensure that the table holds up to the rigors of work.

A majority of the experienced welders recommend a 3/8th inch thick table. This thickness assures minimum warping and damage and is best suited for medium to heavy-duty welding.

For beginner welders working in their home or garage, a suitable welding table top can be around 1/4 inch thick with a 1/8th inch iron frame. (I’m assuming you won’t do too much hammering on it).

This will keep the table light enough to carry in a pickup truck should the need arise. It will not take up too much space and can be used infrequently.

Why Do Welding Tables Have Holes in Them?

Welding tables have holes in them for clamping the objects down. 

Welding tables with holes are called acorn tables. Their holes are about 5/8th of an inch or 16 mm in dimension. These standard dimensions let you clamp your job with standard clamps and are also compatible with a variety of other tools. Clamps help you keep the piece flat that you are welding against the table.

When you weld something, it is also prone to warping due to the high heat involved. Many items tend to get bent out of shape or end up with the wrong dimensions.

The table’s holes and clamps let you hold the item down firmly so you can hammer it back into the right shape or dimension. I often move the clamps to different holes to keep my workpieces secure.

What Is a Good Size for a Welding Table?

The size of a welding table will mainly depend on the availability of space in your workshop/garage, the kind of welding you do, and whether or not you need a stationary or a portable table.

A portable welding table of 3 feet by 4 feet is a good size to have. It is not enormous which makes it easy to store and keeps it portable. It can easily fit in a pickup truck and can be moved around.

This size also lets you put a lot of materials and tools on the table and, at the same time, isn’t too big that it requires you to put your back to it to push it. You also won’t be banging into it all the time. You can also fit a 3 x 4 ft table through most shop doorways, which is an added advantage.

If your garage is small, you certainly don’t want a 4 x 8 ft table. That would overpower the workspace. However, if you do have the space and do not need portability, then you can go in for the 4 x 8 ft table.

I’m currently fabricating an outdoor welding table from scrap material cut from a truck’s tool rack. Once the frame is completed and in place, I will finish it with a 1/4″ piece of sheet metal I picked up from a junkyard.

Because I intend to do some heavy work on this table I will weld braces to support the top. When you’re choosing a table’s top dimensions, you must consider the height of your table. If you are tall (6 ft and over), you need a table with long legs so you can be comfortable sitting and standing when working.

Does a Welding Table Need to Be Flat?

Yes, flat welding tables offer several advantages over non-flat welding tables. These are:


Welding jobs need a lot of precision and accuracy. Without these elements, the weld could be ruined and the items can be permanently damaged. A flat welding table is considered to be almost 700% more precise than a non-flat table.

Higher efficiency

You simply cannot weld on a non-flat or uneven surface. If you want to do the job right the first time around, then a flat table is a must. A flat welding table helps enhance productivity and can also save you time by getting the job done right in fewer attempts.

Better safety

Welding is inherently dangerous. With an uneven or non-flat table, you increase the risk as you just aren’t in the position to clamp the item down properly. This could cause hot items to fall or fly, hurting you or those around you. This can be very dangerous given the high temperatures involved. 

Flat tables enhance safety by helping you firmly clamp the items down flat against the table. This is very important for your safety as well as for those around you.
