Written by David Rowan / Fact-checked by David Rowan

Welding clamps are the units, patented for anti-slippery firm holding of the versatile thickness of objects. But how to choose the clamps for welding? Well, expert welders search it according to their job size, meaning from thickness and length to material used in the making. 

However, the strength of a clamp’s holding capacity relies much on its construction materials. Iron-made ones may compare to a tank strength, but not rust-free. Whether steel, nickel-plated, and copper-made locking and C-clamps are less damaging than that. 

clamps for welding selection fact & our recommendations

As well, from plumbers to woodworking, welders use it much more than others ones. Like several advantages, a wide range of clamps for welding is available in roadway stores. After careful inspection and time-worthy comparative studies, you can finalize your clamp set. Your choice and time are our major priorities. So, we are here with our experienced and budget-friendly clamps for welding with an utterly reliable buyer’s guide.

How to Select Clamps for Welding? 

Clamp Size

The foremost consideration factor while selecting clamps for welding. Nonetheless, the best construction or superior features may not help whether it is worth your bucks or expensive. Clamp size, in particular, means the clamp’s holding capacity. Determines the thickness of material in between jaws that can hold for joining.

First, measure the thickness, meaning the width and depth of your material. According to that size, buy a clamp that can accommodate its overall thickness. 


Somehow the shape can inhibit its holding capacity. For example, the clamp size varies and shapes like T or C or something else impact this issue a lot. Like the clamp size, if the shape goes wrong, everything you do will have no use. 

Different-shaped clamps offer various advantages while you are working. The first advantage you can avail of is the positioning system. Once you turn it to a position, Hobart 770565, up to 90 degrees, will never hinder work progress. More than that, it will increase your working capacity, like the holding ability. 

Clamps vs. Clamps

We have talked about the clamp’s size, and shape, and now it is the clamp’s variety turn. 

C-clamp: fab for welding, woodworking, and sheet metal fabrication. By far, the entire body costs less than other clamps. 

F-clamp: fab for more accessibility to position and wider opening than C-clamp. 

Locking clamp: ensure better security of item holding, even more than one in an accurate position. Even usable with a single hand. 

Dimide clamp: an in-built wrench that helps to squeeze together materials with excellent fastening. More or less, such clamps come with zinc coating and are copper-plated together. Either with a removable hex head or T-handle.

As much as you want the mouth-opened jaws, neither will find a smarter one than Irwin-manufactured vise grip locking clamps for welding. Open the jaws’ width and secure workpieces in between the alloy steel as as thick the pieces are.

The clamp end jaws, alloy steel in construction, and swivel pads. Both increase the capability of clamps for proper holding with greater security for taper items. On top of that, neither fatal issues arise for the jaws nor for holding materials, all around non-slippery movement.

Withstanding a high heat feature makes it perfect for welding clamps performance. And the turn screw? Whether the classic trigger release gives the highest ability, in that case, is quite instant, the turn screw adjusts the created pressure and placement of your workpiece. Consider it like a plumbing essential.

6. Hobart 770150 MIG Multi-Function Welding Plier

[amazon fields=”B001FOPXJS” value=”thumb” image_size=”large” image_align=”center” image_alt=”Hobart 770150 MIG Multi-Function Welding Plier”]

  • Weight: 7.2 pounds;
  • Installation method: tig-welding.

It is a multi-purpose plier, which plies everything. Confused? Well, it is small and similar to a clamp for welding, but not by the exact structure. Else, thinking of using it in heavier tasks, abort the plan. However, it is well enough for smaller tasks, for instance, cleaning debris from a nozzle. 

But you can move with it for mid-sized automotive applications. However, we find it useful in such cases. But the fact is, only a .15” gap in between the steel jaws for welding could not make us happy as per our expectation. 

Because of less holding capacity, such small joints with glues could suffer a lot. Its side-to-side mismatching left it behind similar products. But one thing you cannot avoid is never tightening down its performance. Even it works like a wire cutter as well. 

What we liked 

  • Long-lasting performance;
  • Rust free;
  • High heat-resistance.


  • Perfect for smaller jobs;
  • Expensive.

7. Hobart 770565 Two-Axis Welding Clamp

  • Weight: 1.85 pounds;
  • Clamp-style: two-axis.

Aiming for a 2-axis welding? Neither will find a better one than Hobart 770565. Suppose you love to weld channel iron, round tubing, or square-shaped ones.

More or less, its forever solid patent is perfect to weld on 90 degrees of the mentioned materials. The opening ranges from 2.5 to 3.5 inches -either 2 ¾” or 2 7/8” diameter workpieces it accepts in between the heaviest jaws. On top of that, the acceptance will be about creating miter corners, formed as a “T” shape. 

Worrying about the mismatch with angles from what you are going to do? Without measuring much, you can go ahead and position the miter corners.

And this is never going to harm your clamps or the workpieces. Because of the hard suppository anti-heat materials, it means prolonged heat exposure. Such as product fixing at the right angle, right?  

What we liked 

  • Capable of T welding;
  • High-angle fixing welding clamp;
  • Resist rusting.


  • Only for skilled persons.

8. Wilton 44324 Ac-324 Clamp for Welding

[amazon fields=”B002M97N52″ value=”thumb” image_size=”large” image_align=”center” image_alt=”Wilton 44324 Ac-324 Clamp for Welding”]

  • Weight: 2.6 pounds;
  • Miter angle: 90 degrees;
  • Material: cast aluminum.

Last but not least, in our clamps for welding list. Well, it may be lacking compared to other models. But something which has compelled us to prioritize our listing is the never-breakable bank feature. This means the clamp’s right angling power, is at least 90 degrees. 

Its 2.75 miters create capacity, 4” throat and 2.25” jaw length increase the glue-to-dry performance quite expensive within short notice. Through the cast aluminum in construction, you can optimize the expected build like a tank. So, work around the clamp area is relatively seamless now, right? 

We agree as we have dealt with the same thing, and it’s superb. Lead to the T joints, yes, it gives access. If you expect an auto-adjustment to block, you can accommodate the thickness and sizes of materials. 

What we liked

  • Inexpensive angle clamp;
  • Cast aluminum construction;
  • Offer excellent accuracy.


  • Poor finishing.  


Can Kant Twist Clamp Beat C Styled or Dimide Styled Clamp?

Speaking of Kant, the Twist clamp comes with in-built parallel jaws. Intends more to clamp materials from being moved from the exact place. Including the handle, perpendicular to the clamp, stop twisting the clamp while you are fastening it. 

On the other hand, the C-styled and dimide clamps. Famous for stretching jaws’ width to hold the thickest items. And the dimide clamps, you can finalize every project according to their interchangeable arms. Also, the zinc coating and durable copper in construction make it rust-free and long-lasting for a wide range of applications. Among these tools, we prefer the C-clamp most, and it can beat others.

How Much C-clamps Measure?  

We have mentioned how much the jaws’ opening is vital for the clamp users as per their materials needs. A thumb rule always a potential user should remember is that the higher the capacity, the wider range of object base you can enter by extending the threaded screws.

As well, the clamp’s throat becomes a big deal too. Measuring the extent of the adjustable screw center means the inside frame supports the object’s thickness. 

How to Store Clamps?

In general, the storage system is possible by hanging clamps on the wall or hard surfaces with a hook. It is quite simple. First, drill a hole in the upper surface of the caps. Then place a nut by tightening a durable, anti-slippery eye bolt. Now use it for clamping the pipe clamps or similar ones on your wall. 

What Are the Benefits of Using a Clamp for Welding?

A clamp can be used for welding to hold two pieces of metal together securely while welding. This allows for a more stable and consistent weld. Additionally, using a clamp can reduce the amount of warping or distortion of the metal during the welding process. Overall, the use of a clamp can improve the quality and strength of the weld, and make the welding process easier and more efficient.

Final Thoughts

Such holding capable tools not only establish your corners but also make perfect angles with less effort. 

If your welding clamps are for household or DIY projects, you should check previous worthy components in this content and pipe clamps regarding ones. These qualities and durability are perfect for pro-graded welding and similar jobs without wasting time in searching.
