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 clamp’s holding capacity. Determines the thickness of material in between jaws 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 the shape like T or C or something else impacts 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 clamps size, shape, and now it is the clamps’ 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 accessible 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 through 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.

Want to hold your wicker item in place with an iron welding C style clamp? Then, 4027 by Tekton is the right one for you if you are a potential customer either you want to avoid glue to dry or epoxy. 

Its 6-inches opening capacity is a breeze even for those new welders who have never tried such an iron clamp. The patent is something to attach something by holding in between swivel floating jaws. Even the cast i-beam patent, combining a malleable iron frame, speaks of strength, as well as durability.

Click on the Image to >> View on Amazon

  • 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 us a lot. Its side-to-side mismatching left it behind from similar products. But one thing you cannot avoid, is never tighten down its performance. Even it works like a wire cutter as well. 

What we liked 

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

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 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 “T” shape. 

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

And this is never going to harm your clamps, nor 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

Click on the Image to >> View on Amazon

  • 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. Means clamp’s right angling power, 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 for 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 need. 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 from the adjustable screw center means the inside frame supports the object thickness. 

How to Store Clamps?

In general, the storage system is possible by hanging clamps on the wall or hard surface 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. 

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.
