Stacks of dimes are usually seen in the case of casting when the casting freezes or cools, and one part of the casting looks different from the other part. Piles of dimes Look are made by a human welder or a robotic welder, and stack dimes are used to fill large gaps in the metal.
“Stacking Dimes” is the process of heating the base metal by gas welding and introducing a small drop of filler rod into the molten base metal and each drop forms a small ridge. Stack Dime’s drop is formed by MIG welding. Thus forming innumerable small drops and repeating themselves in each cycle.
Casting is usually used for thick and large materials. It employs commonly used wires that act as both electrode and filler components. MIG (metal inert gas) welding is much faster than TIG (tungsten inert gas) welding, resulting in less lead and significantly lower production costs.
7 Simple Steps To Do Stack Dimes MIG Welding:
Here, I will describe a basic guide to MIG welding. Hopefully, you will know the general method of Stack Dimes MIG Welding through this. Find out what the steps of MIG Welding can be like, and what you need to do to get good results.
Step-1: Machine Set-Up
Since you are going to work with a welding machine, you need to know about it well. You need to know the actual use of how the welding machine works. A MIG welding machine has 4 separate parts. These parts are highlighted separately below.
- Spool Filling:
Inside the welder are a roller and a spool. The metal used to make the welding material is placed inside the welder in this spool. Depending on the type of metal the joint will be made of, metal is added to the spool. These welders are usually used to bind metal or thermoplastics together. If you want to cast aluminum, your wire color should be silver.
- Welder’s Gas Tank:
There are many sizes of MIG welding gas tanks in the market. If you are a hobby welder, use these three main sizes: 40, 80, or 125 cubic feet (“cf”). MIG contains gas mixing tanks (75% Argon, 25% CO2) or 100% Argon in the gas tank. Check that the valves in the tank are full. For this, it is best to open and test the main valve. Gas tank gauge ranges from 0 to 2,500 PSI. The regulator should be fixed depending on the type of metal you will be casting. The regulator is usually set between 15 and 25 PSI.
- Welding Gun Set-Up:
The welding gun contains the usable electrode wire. The welding gun is attached to the MIG welder to maintain the power supply between the wires. The welding gun has a trigger, with which you can control the flow of electricity and feed the wires. This gun creates strong pressure between the wire and a metal workpiece. The pressure generates heat which fuses the workpiece material, and the wire material to form a weld. The most important thing to pay attention to when welding is here.
- Ground clamp selection:
A ground clamp is used to attach the ground cable to the workpiece. It is directly connected to the work or to the table on which the work will be done. Welding wires, ground wires, and electrode wires are important parts of the welding circuit. Select the ground clamp considering the authority and local conditions.
This ground clamp completes the circuit between the cathode, the welding gun, and the welder of the T circuit. The ground clamp connects well with the welded part to work. Any rust or paint should be removed to prevent it from interfering with the work.
Step-2: Wear Safety Equipment
You should take the safety measures of MIG welding seriously, as this welding emits a lot of heat and harmful light, so you need to take some steps to protect yourself.
- Wearing Welding Mask:
It is usually recommended to wear a MIG welding helmet with lens number 6 for work up to 30 amps. And if it is more than 400 amperes then lens number 14 is recommended to be used. (See table below).
| Current (amps) | Minimum Protective Shade No. | Suggested Protective Shade No. (Comfort) |
| Less Than 60 | 7 | 7 |
| 60-160 | 10 | 11 |
| 160-250 | 10 | 12 |
| 250-500 | 10 | 14 |
Close your eyes as soon as you start casting, if you can see the arc then you need to wear a darker lens.
- Wear Steel-Clad Boots:
Steel-clad boots are severely durable. They are made from Overgaard leather so they have to be worn for a long time after casting. You should wear it to prevent abrasion around the cast. Also, it protects from sparks.
- Safety Goggles:
Welders need to wear safety goggles to protect their eyes from the flash. Welding without these goggles can cause permanent damage to eyesight. You must wear goggles with a side shield compliant with ANSI Z87. Goggles also protect the eyes from dust and radiation. GMAW usually uses goggles numbers 11-12.
- Covering Long Hair:
If you have long hair, it should be covered. If you don’t, I would suggest a French braid for your hair. If you don’t do this too, you can tie it back and braid it. Follow any one of these. I would suggest wearing a French braid and a helmet.
- Protective Clothing:
You must protect your eyes, face, and body from sparks, ultraviolet radiation, and hot metal when welding. For this, you need to wear oil-free, non-melted, flame-resistant protective clothing. Authorized protective clothing includes under-sleeves, aprons, jackets, and coats, and includes. You can also wear leather leggings.
- Leather Gloves:
Casting is a very risky job so you need to wear gloves to protect both the wrists and the hands. This will help protect you from electric shock. Gloves also provide improved grip during casting and prevent abrasion. These MIG welding gloves are made from top-grain cowhide and goatskin or deerskin.
- Casting Sleeve:
This cast sleeve is made from treated cotton. It protects you from heat and sparks. It is lighter than leather and provides better protection. Sometimes welding rays, sparks, spatters, and molten metal are worn on your arm. This sleeve is pulled over the wrist during casting which protects you from the spark of fire during casting.
- Knee Pads:
It will protect you from abrasions, cuts, and heat. They are light, flexible, and overall comfortable. Using a knee pad reduces the impact felt on your knees and protects your knee cap. These give you a more comfortable feeling. Knee pads should be worn on tasks that take a long time on your knees, such as welding, roofing, tiling, and more.
Step-3: Prepare The Weld
Care must be taken to ensure that the joints are free of grease, oil, wax layer, and paint before welding the workpiece together. Also, the following points should be kept in mind.
- Check To Shield Gas Valve:
Make sure the shielding gas valve is open. Then check if 20ft3 / hour is flowing in the regulator. Turn on the welder and attach the grounding clamp to your welding table. It also allows you to attach directly to the metal. Then you have to do the power setting.
- The Metal:
To weld by MIG Welder, hold the trigger, and touch it on your workpiece. Did you see a great result? Yes, it was a wonderful experience. Now give this casting 5 minutes to strengthen and clean the metal. This will help you to add any broken edges.
Step-4: Placing A Bead:
A welding bead is made in a single operation during the welding process. Notice how the cast is evolving during casting. See if the pieces of the material are melting together. If you see a hole in the workpiece, it means that the energy has become too much which is causing the solder to melt.
And if you see that welding is being made in the sport, you have to understand that the power settings have become very low. Welding will look very smooth and beautiful if the setting is right.
Step-5: Welding Metal Together
All checked so now you can start your welding work. You can continue welding as you wish. However, it is better to cast any stock from the bottom to the top. Pushing upwards or forwards with a welding gun. But in the beginning, you can start from any direction.
Step-6: Grind Down The Weld:
This depends on how skilled you are at welding. If you can do welding well, grinding may not be required. However, if welded well, the welded metal becomes more beautiful and smooth. However, it has some bad effects such as grinding and weakening the metal. Therefore grinding should be done carefully to maintain the integrity of the structure.
Step-7: Turn Off The Welder:
Since the work is almost finished, turn off the power supply and machine to turn off the welder. Open your gloves at the end of all, and keep the safety equipment open one by one. Keep goggles, your helmet, etc. open. One thing to keep in mind is not to touch the welded object immediately, as it may be hot then. Once the metal has cooled, remove the ground clamp and loosen the gloves.
5-Step To-Do stack dimes with a stick welder:
Stick welding is also called “arc welding”. Stick welding does not require any shielding gas like MIG and TIG welding. Due to this, its cost is low and welding can be done in any environment. Below I will describe how to do stack dimes welding with a stick welder.
Step 1: Set Up The Welding Machine:
First, you have to set up the welding machine. Because different metals have to be set differently. The electrode you use will determine whether you use AC (alternating current) or DC (direct current). Any welding machine has these two types of systems. DC is better if you are welding thick metal, and AC is better if you are doing thin metal welding.
After setting the current you have to set the amperage. You can set 1 amp: at the .001 inch diameter electrode. With this, you can start and gradually increase it as needed.
Step 2: Maintain arc length:
The distance between the electrode and the workpiece is called arc length. Since it is a “constant current” welding process, the welding voltage depends on the arc length. So a constant arc length is to be maintained while welding. If the electrode gets stuck in the workpiece, then the Arc length has decreased. If there is too much spatter or undercut then you have to understand that the arc length has become too much
Step 3: Arc Angle:
You always have to keep track of the degree to which your electrode is used. Generally speaking, welding should be done by holding the electrode at an angle of 10 to 15 degrees from the plane space. This angle will give the best results.
Step 4: Manipulate the electrode:
You can run it at a steady line or at “whip and pause” speed. Welding is an art, when you become proficient you will know for yourself which method will be best for you. Welding should be done where there is no gap.
Step 5: Travel speed:
Travel speed lets you know how fast you are welding, that is, how fast the stick welder’s gun is moving in the workplace. If you divide the distance by time, you will get the average travel speed of stick welding. The travel speed of the welding machine is a very important factor in arc welding. The speed of travel determines how much heat is accumulating in the workpiece.
What Are Stacking Dimes In Welding?
If you want to know more about dimes stacking, you must have a keen interest in welding art and its aesthetics. The term “stacking dimes” is closely associated with welding. In the general case of casting, the term describes the strong wave of casting beads.
From a mechanical point of view, welding is very important. This is largely based on the geometry of the weld. This welding can sometimes be harmful, such as the erosion of small pockets between “dimes” which can be very damaging to the instrument. But in my opinion, it looks great. Its appearance will become more aesthetic when you mold the highly visible parts with less mechanical stress.
Which Welding Wire Is The Right Choice For MIG Welding:
You need to choose the right wire for the MIG welder. Then you need to make settings for casting. This setting depends on the strength of the welding you are doing. As like, you need to use 40-90 volts for welding with this 0.6mm diameter wire. Too many volts can be harmful to this wire. Here is a table you can see the ratio of wire dia and volt:
| Type Of Welding Wire | Wire Dia(mm) | Welding Current |
| Solid | 0.6 | 40~90 |
| solid | 0.8 | 50~120 |
| solid | 0.9 | 60~150 |
| solid | 1.0 | 70~180 |
| solid | 1.2 | 80~350 |
The welding machine will have to make repetitive adjustments if it does not find the “flow” of the welding material. This time I will tell you about welding gas. I think for MIG welding it is better to have 75% argon as well as 25% CO2. The combination of superior argon content is very good for MIG welding. Now it’s ready to hood and shoot the stacking dimes.
Related Question About Stack Dimes MIG Welding:
Which Angle Should Be A MIG Gun?
One was to say 90-degrees. The position of the metal to be welded must be flat. When welding a butt joint to a 180-degree joint, the welding operator must ensure that the MIG welding gun is attached to the workpiece at a 90-degree work angle. It also depends on the thickness of the base material for which the gun has to be pushed at a torch angle of 5 to 15 degrees.
What Pattern Would You Use For MIG Welding?
You must always follow the steady motion welding pattern. Because
A steady speed is the most basic technique of welding and it is necessary to set the MIG welder correctly. This pattern can be well followed for welding by robots. This pattern can be welded perfectly in any position.
Do You Push Or Pull A MIG Weld?
Joint strength is the most important factor in MIG casting. Pushing the welds penetrates the welding material downwards, creating a wide and flattened bead that is beautiful to look at. On the other hand, a thin and round bead is formed if you pull the cast. When welding penetrates deep, the strength of the joint is relatively high.
Why Is Stacking The Weld Necessary?
This stack is not very liquid, so it is very good as a filler in welding. This stack can create clean and consistent weld bids. Hence, stacking the weld is very necessary. This form of weld affects the waveform. These settings will be affected by the AC frequency.
How Dangerous Is MIG Welding?
This MIG welding is not dangerous if you use low to medium voltage. It is an open circuit voltage that does not allow life to be in contact with the workpiece. If your body gets wet then some amount may get burnt. Its electrodes will give you a shock if you replace it in wet soil.
Conclusion:
Here you will find out what MIG is, how it works, and how to stack dimes that are used in MIG welding. With this, you know what safety is required while doing MIG welding. Here’s how to use them. Considering the other methods of welding, you will find that stack dimes MIG welding is a very straightforward technique.
