As you probably know, every welder needs a slag or chipping hammer to remove slag from the weld seam. A friend of mine showed me his brand-new slag hammer, and I was impressed how good it works compared to my old chipping hammer.
So I started a detailed recherche on slag hammers and created this list to show you guys the best slag hammers money can buy.

The first item I’d like to show you is the Estwing Big Blue. The Big Blue is a rugged welding hammer made in the USA: Manufactured by Estwing in Rockford, IL only the finest American steel is used for this first class chipping hammer.
Since the Big Blue is forged in one piece, it surely is a long-lasting piece of equipment. Moreover, according to the manufacturer, the shock vibration grip can reduce shock vibrations by up to 70%.

Slag & chipping hammer for welding – things to know
Why is there a slag?
Now let’s take a look at the theory. Slag comes from the flux which melts during the welding process. Moreover, at flux-core arc welding, the flux is a necessary shielding material that covers the molten metal weld zone and protects it from reacting with atmospheric gases like oxygen.
The slag needs to removed before you add another weld layer or before you further process your weld seam.
Typically a slag hammer is only required for arc welding because MIG and TIG welding does not produce slags.
See the removal of a welding slag in the video below:
How to remove the weld slag?
After your weld seam is finished, the slag is not required anymore.
Thus, hit the weld seam with your slag hammer to shatter the slag. If you want to remove weld spatter, you can use the flat side of your chipping hammer and slide over the metal surface. After your treatment with the hammer use a steel brush to finish the seam.

Side note: You can resharpen the hammer’s edges when they become blunt. If you need something to transport your weld tools, you should also check out our thread on welding bags here.
