How to Keep a Welding Table From Rusting [Explained]

by WeldingWatch

Welding tables are the backbone of any metal fabrication or repair project, they hold everything together (literally). But let’s be real, if you want to keep your table from rusting like a forgotten bottle of ketchup in the fridge, you gotta keep it clean and dry. Trust me, you don’t want to be the one who gets blamed for a weak weld because you didn’t maintain your table properly!

So, how to keep a welding table from rusting? The most effective solution is to spray WD-40 from a spray bottle and leave it to sit. Do NOT wipe it down; WD-40 is an excellent tool for rust prevention.

I’m going to cover the causes of rust on welding tables and provide you with a step-by-step guide on how to prevent rust from forming on your table!

Why Does My Welding Table Rust?

First, let’s understand rust and how it forms. Rust is a reddish-brown oxide that forms when metal is exposed to water and oxygen.

This process, known as oxidation, can weaken and damage the metal over time.

Rust isn’t just unsightly on a welding table; it can also make it difficult to secure the materials for welds.

There are several common causes of rust on welding tables.

Moisture is the primary culprit behind this issue, and it can come from numerous sources like humidity, rain or condensation.

Heat can cause metal to expand and contract, resulting in minuscule fractures that enable oxygen and water access to the metal – a major contributor of rust.

How to Keep a Welding Table From Rusting

To prevent rust from forming on your welding table, there are several steps you can take.

One of the most important steps is regular cleaning and maintenance.


My top recommendation for maintaining your welding table and keeping it rust-free is to use WD-40.

WD-40 was developed in 1953 as a tool to keep missiles from going rusty!

The most effective way to use WD-40 is in a spray bottle, similar to general household spray bottles. The idea is to cover the welding table in WD-40 and let it get to work; there’s no need to wipe it down, so leave the WD-40 to spread around the table and get a thin coat on there.

Mild Detergent

You can also use mild detergent and water to clean the table, and make sure to dry it thoroughly afterward. This will remove any dirt and debris that could trap moisture and lead to rust.

To further prevent corrosion and rust, you can coat your table with a protective paint or coating. This creates a physical barrier between the metal surface and outside elements that could corrode it.

To ensure maximum protection, inspect your tabletop routinely to make sure the coating is still intact and reapply as needed.


Rust prevention is key when it comes to welding tables, and storage plays a major role in that. A dry, well-ventilated area should be chosen as the table’s environment of choice.

Your investment should be safeguarded by covering the table with a protective cover whenever it isn’t being used, after all, welding tables aren’t cheap!

This will help to keep moisture and debris away from the table.

Rust Inhibitors

In addition to these steps, you can apply rust inhibitors such as oil, wax, or silicone on the table’s surface and use a vacuum cleaner to remove any debris and dust.

Cleaning the table with a wire brush before applying rust inhibitors can also help to remove any rust that has already formed.

How do You Maintain a Welding Table?

Maintaining a welding table is important for ensuring its longevity and keeping the work surface clean and safe.

Here are few of my tips for maintaining your welding table:

  • Clean the table regularly: Use a wire brush to remove any debris, rust, or welding slag from the table surface. This will help prevent rust and corrosion from building up, weakening the table and making it less stable.
  • Protect the table from moisture: Moisture can cause rust and corrosion to form on the table, so it’s essential to keep the table dry. Use a cover to protect the table when it’s not in use, or store it in a dry place.
  • Check for wear and tear: Regularly inspect the table for any signs of wear and tear, such as cracked or bent legs, loose bolts or screws, or warping of the table surface. If you notice any of these issues, repair or replace the table as needed.
  • Lubricate moving parts: If your welding table has any moving parts, such as adjustable legs or clamps, make sure to lubricate them with light oil or lubricant to keep them moving smoothly.
  • Take care when welding: Welding can cause heat damage to the table, so it’s important to use a heat shield or insulating material to protect the table when welding. Also, avoid welding too close to the edges of the table to prevent warping.
  • Keep it organized: Welding can generate a lot of debris and clutter, so keeping your welding table organized and clean is important. This will not only help to keep the table in good condition, but it will also make it easier to find the tools and supplies you need when you need them.

Frequently Asked Questions:

Can you paint a welding table?

Absolutely, you can give your welding table a new look with rust-inhibiting paint. Before painting, please make certain to clean the surface of any debris or contaminants that may affect its adherence. Moreover, when performing welding activities on the painted table always use an insulating material or heat shield for added protection against potential damage from high temperatures.

Does wd40 affect welding?

Not really; using a lot of WD-40 does have the potential to accelerate your welding cooling rates, but it’s not going to have any significant effect if used in sensible amounts.


So there we have it! Rust can wreak havoc on a welding table, making it difficult or impossible to properly secure materials that need welding.

It’s really important you understand the causes of rust and take the necessary steps to prevent it; so you can ensure your welding table remains in good working condition for years to come.

WD-40 is going to be your number one tool when looking to prevent rust; other than that, general maintenance is the way forward!
