To push or to pull your weld.
One of the oldest debates that are still ongoing regarding the welding with a MIG welder includes what to do with your weld – is it pushing your weld or pulling it?
Hence, what is actually meant by pull or push your weld? In the event you push the weld, it implies that the weld MIG gun angle would be at the back of weld when you push the puddle and make the bead.
The weld gun will be in the front of the weld if you pull a weld, and also you will be pulling the puddle.
Both kinds of welds set up a great bead when it reaches down to it and can perform amazingly in distinct conditions.
You’ll get more clarity by going through the pros and cons of pulling or pushing your welds.
Pros and Cons – Pulling your Weld
Pros
- You’ll get intense or profound penetration into the base metal if you pull your weld.
- It can easily grab both the pieces of base metal together, and as a result, it will be a more durable weld.
Pulling a weld is perfect if a welder wants to know how the weld bead will look after a pass. If you are welding steel, then pulling a weld is a good option. However, various factors decide your direction. These include the process, kind of metal, or any other points that can adjust or modify your weld’s approach or angle.
Cons
- This is not as smooth as a weld and has a somewhat more rounded appearance.
- You may observe that the weld isn’t gracefully pleasing. So, it doesn’t appear to be great and can still need grinding if there is a requirement for more smoothening.
Pros and cons – Pushing your Weld.
Pros
- You will make a much smoother and flatter wider puddle that will bind into an excess of the base metal if you push your weld.
- If you are looking for a smooth flat-looking weld, then the outcomes will be somewhat more beautifully pleasing to the eye.
You can see where you are approaching if you are pushing a weld. So, in order to get better penetration and visibility, the majority of the welders push the welds uphill.
Cons
- The weld doesn’t penetrate profoundly into the base metal, and as a result, it will not be as powerful as a weld.
- The weld will not hold up in the event when weld occurs in an excellent stress condition.
You need to keep this thing in mind that you should never perform one above the other. Each kind of weld has its position, and if performed accurately, you can use the tool in your arsenal just like a welder.
Well, don’t get confused that there is only one way to weld, either by pulling or pushing. You can perform both kinds of weld in one go.
You’ll get to know more about this in the following sections.
What should you do should you push and pull a weld?
Now, you are aware of all the pros and cons of both pull and push your weld. You must be thinking when you can make use of one or the other or both.
If you want to begin, you must understand that every situation is not a perfect one for pulling or pushing your weld.
You’ll be having only one option of pulling or pushing your weld. It is the case when you are doing the job in a congested space, and it isn’t permitting the nozzle of the welding gun to adjust in a particular spot.
Just, for instance, suppose you need to weld a frame on a bike. So, it will be difficult for your weld nozzle to adjust in this place, and as a result, you need to either pull or push your welds.
Instances of When to push a weld
A fantastic instance of pushing a weld is when you are welding straightly downwards, i.e., you are welding vertically down.
You’ll also have an option to pull the weld down; however, pushing it will bring a smother flatter appearance.
Instances of When to pull your weld
You can think of a situation when you weld an I beam for a bridge. The penetration will be amazingly greater if it could be able to gap the I beam an 8th of an inch far away and pull the weld over that gap.
So, in this scenario, you can get a greater penetration so that it can offer a powerful strength if you are welding a thing that needs to be structurally great.
Instances of When to do both
Now, you must be thinking when you can perform both a pull and a push in the same weld bead. In this case, you’re performing a weld on the portion of a half-inch rod to a flat, so you can try the trick.
You can do this by beginning on either side of the rod performing one pass, pulling it back across, and the other by pushing it.
You need to be smarter and creative with all the choices that you have as a welder. If you want strength, then you need to pull your weld. If you wish to clean weld, then opt for pushing your weld.
When should you NOT push your weld
Another thing that you need to understand is that make use of flux use wire rather than a shielding gas.
The tubular wire contains a flux at its core that you’ll be utilizing. It builds up a shielding gas when the flux burns and also makes slag that will sit atop your weld.
Interestingly enough, you have to pull your welds as much as you can do when it comes to this kind of welding. But why? Here is the answer. You will confine the slag in the weld if you push it. And as a result, the bead will get weakened.
In addition to this, it won’t deliver a beautiful appearance and make pinholes.
FAQs – An Insight into Google’s most searched Questions
Is it better to push or pull when MIG welding?
You can either opt any technique, either pull or push. However, keep this thing in mind that pushing brings a fantastic look and permits you to better direct wire into the joint location.
Whether or not should you push and pull a weld?
If you are welding with a flux-core or stick wire welder, then you need to drag the wire or rod. On the other hand, you need to push the wire in case of MIG, i.e., Metal Inert Gas welding.
Final words
So, what’s your answer? Should you push or pull a MIG weld? The conclusion states that several situations can offer a specific technique. Also, the majority of the careful tests rely on the approach, followed by a welder doing the test.
You don’t have to still think about whether to pull or push your weld as long as you have your approaches, tools, and settings set up appropriately. This is the major thing that all the welders should acknowledge regarding this debate about MIG push or pull. That’s all for today.
