How COVID-19’s quarantine affected the CO2 shortage
We have seen numerous photos of the positive effect that the quarantine had on the environment. From night skies being brighter to waterways becoming clearer. The fact that less vehicles on the road benefited Mother Nature is hard to dispute.
With less people driving comes lower fuel production. According to the U.S. Energy Information Administration, "COVID-19 mitigation efforts resulted in the lowest U.S. petroleum consumption in decades." The was a 41% decline from January 1 – March 13, 2020 in motor gasoline and a whopping 62% decline in jet fuel.
So, what does this have to do with the carbon dioxide (CO2) shortage you ask? Less driving and fuel consumption means less ethanol production. Less ethanol production means less CO2. The carbon dioxide that we use to carbonate beverages and produce dry ice is a by-product of ethanol production.
Ethanol is typically made as additive to gasoline from corn, sugar cane and sugar beets. The resulting CO2 from the process is captured and reused. CO2 can be produced and captured from a variety of processes, but the purity of beverage grade CO2 is 99.9% pure. Not all processes result in CO2 capture that has these few impurities.

While more people are on the road now and fuel consumption is creeping back up, it will take a while before supply catches up with demand. Industry experts expect the shortages to last through at least the end of 2020. This drives up the cost of CO2 and its availability. It also plays a significant part in the availability of dry ice that is made from compressed CO2.
During an extended power outage, such as the one caused by Tropical Storm Isaias, refrigerated and frozen foods may spoil. A great way to preserve your groceries that need to be kept cold or frozen is with dry ice.
Dry ice is very cold. -109 degrees F cold! It can help keep frozen foods frozen and refrigerated goods cold. Here are some guidelines from the U.S. Department of Agricutlure:
The Center for Disease Control (CDC) also offers this power outage food safety infographic:
AllGas is the premier manufacturer of dry ice in the area. Made to order in Monticello & New Hampton (Goshen) and in storage at our Newton location, we offer dry ice as 3/8″ pellets and 1/8″ rice.
Dry ice is made from solidified carbon dioxide (COs). Called "dry" because when it sublimates (goes from a solid to a gas) it doesn’t leave any moisture behind. That’s not the only difference between regular ice and dry ice. Dry ice is exceptionally cold – it sublimates at -109° F – that’s cold! It also lasts long which makes it the perfect "ice" for portable coolers.
Dry ice is used in a variety of commercial & residential applications. It is used in:
A relatively new addition to our dry ice manufacturing is the rental of dry ice blasting equipment. Dry ice cleaning is like sand blasting except for no secondary waste. The dry ice evaporates leaving less clean up. It also is non-abrasive and non-toxic.
Dry ice cleaning/blasting is used in a diverse list of industries. From automotive to graffiti removal, it is the preferred method for high pressure cleaning.

Graffiti Removal with Dry Ice
Many building owners have struggled with how to remove graffiti, and often simply resort to painting over it. In the past, the only other option was to sand or soda blast the graffiti, but that can result in damage to the building as well as extensive clean-up. Many building owners, especially those owning historical buildings, have decided to turn to the use of dry ice blasting when removing graffiti. Dry ice blasting is time efficient and effective when removing graffiti from almost any surface, and it causes little to no harm to the existing building.
Benefits of Dry Ice Blasting for Graffiti Removal:

What is Dry Ice Cleaning? Environmentally responsible cleaning & surface preparation!
How it works
Dry ice cleaning is similar to sand, bead and soda blasting in that it prepares and cleans surfaces using a media accelerated in a pressurized air stream. It differs in that dry ice cleaning uses solid CO2 pellets or miroparticles, which are blasted at supersonic speeds and sublimate on impact, lifting dirt and contaminants off the underlying substrate.
The unique characteristics of dry ice make it the perfect cleaning media. Dry ic is non-abrasive and non-conductive and will not damage surfces or equipment. It sublimates on impact, leaving behind no secondary waste. It is non-toxic and safe for employees.
These atributes make dry ice cleaning a efficient, cost effective and enviornmentally responsible cleaning solution.
The power of Cold Jet dry ice innovation brings winning solutions to a diverse list of industry leaders around the globe.

Scientists from Heriot-Watt University have welded glass and metal together using an ultrafast laser system, in a breakthrough for the manufacturing industry.
Various optical materials such as quartz, borosilicate glass and even sapphire were all successfully welded to metals like aluminium, titanium and stainless steel using the Heriot-Watt laser system, which provides very short, picosecond pulses of infrared light in tracks along the materials to fuse them together.
The new process could transform the manufacturing sector and have direct applications in the aerospace, defence, optical technology and even healthcare fields.
Wedding, bridal or baby shower, maybe an anniversary or birthday party? If you’re searching all over for helium, give one of our AllGas stores a call. We carry several different size helium tanks that you can’t buy in a big box store.
Before you rent a helium tank, you need to know how many balloons you need or want. Balloon size also plays a part because different size balloons hold different cubic feet of gas. See the chart below.
For example a 10″ balloon, properly inflated, holds .30 cu. ft. of helium. Say you were using the balloons as centerpieces and wanted to fill 100 10″ balloons. Here’s the math: .3 cu ft X 100 balloons = 30 cu ft of helium. We rent a 40 cu ft tank that would work perfectly.

Welding defect can be defined as any deviation in size and shape of the given metal structure regarding technical and design requirements. The deviation can be caused by process limitation in terms of wrong welding process/technique or due to certain human behavior.
Welding defects can occur at any stage of the welding process and they can affect both the inside and outside of the metal structure. Although it is almost impossible to create a defect-free weld, it is important for you to reduce their occurrence to prevent loss of material and maintain the intended quality.
It is important to note that some of the defects are permitted if they do not compromise set standards and quality, but some like cracks cannot be accepted. Having said that, this guideline will help you to detect these common welding defects, their causes and remedies.
Types of Welding Defects
Defects in welding joints are classified into 2 broad categories .i.e. those that occur internally and those that occur externally.
External Welding Defects Explained
Cracks – Cracks are the most common defects and they can occur anywhere on the surface of the weld material. Some cracks can also be present inside the weld material especially on areas that are affected by direct heat (HAZ). Cracks presents themselves in two major types:
Causes of Cracks
Overlaps – Overlap results when the weld pool overflows on the surface of the weld metal. The molten metal does not fuse with the base metal leading to an overlap which may extend to form an angle not exceeding 90 degrees.
Causes of Overlaps
Undercuts – Undercuts presents themselves as narrow gutters on the base metal next to the weld metal near the edge. This occurs when the base metal melts away from the weld area reducing the thickness of the base metal and the result is a weakened workpiece. These undercuts run parallel to the metal weld.
Causes of Undercuts
Porosity – Porosity is a condition that manifests itself inform of gases or air bubbles that are trapped in the weld metal. It is mainly as a result of contamination of the weld metal, which is weakened, and it can collapse with time.
Causes of Porosity
Spatter – Spatter occurs when metal particles from the weld is stuck on the area adjacent to the weld area. This defect is common in gas metal arc welding and it is sometimes very hard to remove the particles.
Causes of Spatter
Internal Welding Defects Explained
Incomplete Fusion – Lack of fusion or incomplete fusion occurs when the weld metal and the base metal are not accurately welded due to improper melting resulting into unfilled gap. Improper fusion can also occur between layers within the weld itself. Although this is an internal problem, it can be manifested on the outer surface too if the outer sidewall is not properly fused with the parent metal.
Causes of Incomplete fusion
Incomplete Penetration – Incomplete penetration results when the depth of the weld is not enough. As such, the metal grove is not filled fully meaning that the weld does not extend through the entire joint.
Causes of an Incomplete Penetration
Slag Inclusion – Slag inclusions are compounds such as oxides that are mainly trapped in the weld or on the surface of the weld zone. These compounds are byproducts of welding processes such as stick welding and arc welding. In addition, insufficient cleaning can leave some slag behind which reduces the strength of the weld and it can act as a starting point of serious cracking. Serious slag inclusion may require you to do a re-weld.
Causes of Slag Inclusion
As a parting shot, we can all agree that it is important for you to identify and remove any defect that may be present in your workpiece. We believe that this article has comprehensively addressed those defects and we hope that it will help you during any manufacturing process to prevent loss of material and to keep you safe.
