Do you pull or push a slag Weld?
Any welding process which leaves slag behind will require you to pull. Stick welding, flux-cored arc welding, electroslag welding, shielded metal arc welding, and submerged arc welding all produce slag and therefore require the weld to be pulled rather than pushed. Slag is the nonmetallic byproduct of the welding process.
Should you pull stick weld or flux core Weld?
To elaborate more, you should always pull stick welding as well as flux-core welding. The reason for that is pushing traps slag into your puddle, resulting in poor welds. With regular MIG and TIG welding it is not that crucial.
Should you pull or push when welding?
In processes that don’t create slag (MIG and TIG) there, some people who prefer pulling over pushing, and the reason they give is the visibility of beads as you are welding. When you are pushing you can see where you are going, interestingly this is one of the major reasons in favor of using the push method.
Should you push or pull the weld pool when stick welding?
Stick welding is one of the most commonly applied techniques in the family of arc welding processes. 1 It’s likely one of the first processes you’ll learn about in your welding classes. And there are some important considerations for getting it right: Should you push or pull the weld pool? When stick welding, you should always pull.
Should you push or pull a weld?
While pulling might create a deeper penetration, in most situations, pushing creates a flatter weld that covers more surface area. In some instances, this can create a stronger weld than what you might get with the pull technique. As mentioned, pulling allows you to watch your bead as its being produced.
What direction do you TIG weld?
Tungsten should be held in line with the direction that the wheel is turning rather than perpendicularly. This will ensure the grind marks run the length of the tungsten, which assists the flow of the electric current as it travels down the electrode.
Can you drag TIG welding?

Do you push or pull when arc welding?
Stick welding, flux-cored arc welding, electroslag welding, shielded metal arc welding, and submerged arc welding all produce slag and therefore require the weld to be pulled rather than pushed.
Why is TIG welding so hard?
TIG welding is a more finite process that has more factors at play. You can't just pull the trigger and go like you can with a MIG machine. It is a slower process that requires more care, coordination, and patience. With this being said, TIG is a process that can produce some of the most eye catching welds.
Can you TIG weld in all positions?
TIG welds can be made in all positions - flat, horizontal, vertical or overhead. Perfect for roll cages and inside confined areas.
How do TIG welders stay steady?
In any type of welding, the closer you can get your hands to the arc, the steadier you can be. The closer you can rest your hands or arms against a solid surface, the steadier you can be. It's not always possible to be that close, but it's the general idea. Closer = steadier.

Which weld is stronger MIG or TIG?
Precision: TIG welds are more precise and have a higher general quality than MIG welds. Cleaner process: The TIG process is cleaner and better for the environment. No need for filler: TIG welding doesn't require filler material. Greater control: The pedal used allows for foot control to adjust heat input.
What is the foot pedal used for in TIG welding?
A foot pedal, or foot control, can be used to control the amperage of your welder while you're welding. Weld getting too hot? Ease off the pedal and lower the amps, which lets the weld cool. The foot pedal gives you complete control without having to stop in the middle of a weld and readjust.

Why is my weld bubbling?
Watch your voltage / arc length. The further away the gun is from the weld site, the more likely air and gas will seep into the weld puddle causing bubbles to form which will in turn make a weak weld. Preventing porosity in your weld will overall increase the durability and purity of your weld.

What action will you take just before striking the arc in TIG welding process?
Put the control in an area which is most comfortable. Press the foot control and strike the arc. After a puddle is formed, add the filler rod to the leading edge. To reduce the chance that you contaminate the tungsten, move the TIG welding torch to the back of the puddle when the filler rod is added.
Why is it important to push your welding puddle?
While welding uphill, it is important to push your welding puddle rather than pulling because of how gravity affects the slag. Welding uphill is definitely something you want to practice a lot because it takes time to get the traveling speed right.
Why is the push technique used in a weld?
Using the push technique often results in flatter and wider beads and also fewer penetration levels because the force of the arc is being pushed away from the weld puddle. On the other hand, the pull technique which is also known as the backhand technique is exactly the opposite of the push method.
What is tapping welding?
The tapping method means exactly what it sounds like, you have to tap your electrode on the metal for a fraction of a second and bring it the welding position. This method can be a bit harder to pull off, you might get your electrode stuck or the arc might extinguish. The second method, dragging is like lighting a matchstick.
How to get a good welding angle?
Before starting your weld, try to get your electrode at the right angle. You should aim between 15 to 30 degrees to the vertical . If you are welding thicker materials in general, or materials thicker than your machine should be able to handle, you can lessen the travel angle to 0 for more penetration. That way the arc pierces right into the base metals providing deeper penetration.
What happens if your arc is too long?
If your arc is too long it will not be stable and produce excess spatter and might even go out. On the other hand, if your arc is too small your electrode might keep sticking to the base metal. As a rule of thumb, your arc length should be around the diameter of the electrode.
Why do people prefer push welding?
But usually, people prefer the push method because it offers a better view of the workpiece and lets you to better direct the wire into the joint. But the same situation is not the same when it comes to stick welding, one of the main reasons being that it is one of those methods that produce slag. The majority of the people prefer and swear by ...
Do you need slag removing tools when welding?
Try to keep slag removing tools with you as well, you might not need them during the welding process, but you will them afterward. Another thing to keep in mind is that even though stick welding is the most forgiving for having dust on your metal, you should still clean all the surfaces before starting your weld.
How to tell if a welder is a drag or push?
Make sure that you can see the electrode and the bead as you move across the joint. A good rule of thumb is that a drag weld should move toward your welding hand, while a push weld should move away from the welding hand. That is, a right-handed welder should drag from left to right and push from right to left.
Why pull a stick welder?
You want to pull a stick welder. The reason is to avoid pushing slag into the welding pool and getting it stuck. If slag gets mixed into the welding pool, it will weaken the strength and integrity of the final weld. You want to weld in a way that leaves the slag behind to be removed later.
How to weld uphill?
To weld uphill, start at the base of the weld joint and angle the stick down slightly. Crack an arc and slowly work your way up the joint. Travel speed becomes extra-important for welding uphill.
What is the electrode holder on a welder?
The electrode holder. This is the hand-held device that the welder uses to guide and manipulate the electrode (hence, the arc) during welding. A lead wire that comes out of the end of the electrode holder is connected to either the negative (-) or positive (+) terminal on the welding machine.
How to be comfortable when welding?
Welding is most comfortable when you think about your weld before you lay a bead. Part of getting a nice, even bead is keeping a consistent arc length and stick angle. Think about the position of your electrode and how it will change as it moves across the joint.
What is a weld pool?
In all welding processes, you’re going to build what’s called a weld pool, or a small puddle of molten metal, which you’ll move across the surface you’re welding to join the two pieces together . When pushing a weld, you weld from behind the weld pool and push the entire pool forward as you weld. When pulling a weld, you weld in front ...
Why is arc welding called stick welding?
Welders joke that arc welding is called stick welding for how likely the rod is to stick to the piece your welding. Pulling the electrode as you crack an arc can reduce sticking. As you scratch the electrode tip across the work surface, pulling the stick helps you lift it off the surface to establish an arc.
What is the push method in MIG welding?
The push method of MIG welding is when you put the gun at the back of the puddle, and you push the weld pool forward to make the workable bead. This method does not get nearly as deep a weld.
What is push welding?
The push welding technique is ideal for deep penetration and when there is more area. If you are a rookie to MIG welding and push and pull methods, you want to go in-depth to understand precisely what the difference is. Then, when you pull out your equipment, you will not have to wonder whether to push or pull.
Why is a pulsed MIG welding good?
Pulsed MIG welding is excellent for beginner welders because it gives you the ability to learn how welding works and leaves a nice bead appearance.
What is welding equipment?
The type of welding equipment you are using and the level of performance it produces. The material that will be welded , including composition and strength (steel, aluminum, alloys, etc.) Which welding process you plan on implementing – pulsed, droplet, or short-circuiting. How much surface area will be welded.
When to use pull method?
When utilizing the pull method, you are placing your machine in front of the weld and then pulling the puddle back. The main benefit of using the pull method when MIG welding is that it gives you the ability to see the bead as it is being formed for the weld.
What are the advantages of pulling a bead?
Advantages include: A deeper penetration for a stronger attachment to the base metal.
What is the primary goal of welds?
You have to determine which is ideal for you. The primary goal is to get the best welds possible, regardless of technique. Knowing what is required to accomplish that is what you have to take into consideration.
Why push a weld?
Pushing has the advantage of creating a shallower weld that covers a larger surface area. Depending on the project, this technique can result in a more durable weld than what’s offered by a pulling motion.
What is stick welding?

What is undercut welding?
A common problem new welders face when mastering stick welding is what’s known as the undercut. These imperfections located on the outer edges of a weld detract from the aesthetic appeal of your work while also producing a weak spot that can fail with the right amount of pressure.
What is a weld pool?
These two welding techniques are spoken of in relation to the small pool of molten metal known as the weld pool. You’ll create a weld pool with most welding processes, spreading it across your work surface with your electrode to fuse the two pieces of metal. When pushing, welders work behind their weld pool and push it with their welding electrode, ...
Is stick welding a form?
While some welding processes offer more leeway when it comes to choosing between pushing and pulling, stick welding doesn’t fall into that category. Instead, stick welding demands strict and specific form in order to be performed correctly.
Is welding safety important?
The best welding technique in the world won’t help you much if you get hurt in the lab or shop. So, welding safety is perhaps the most important practice to observe. Fortunately, welding safety is one of the first things you’ll learn about in welding school.
Can you stick weld with 1025 steel?
When stick welding, it’s a good idea to stick with steel that isn’t rich in silicon or sulfur, such as 1025 or 1015 steel. Otherwise, your weldment could have a higher chance of cracking.
