What is the major reason for the weld penetration in CO2 MIG welding?
The heat distribution throughout the arc is different in case of the CO2 gas than Argon cause by the high heat conductivity of the CO2. In addition, the CO2 dissociates at high temperatures (in the arc) and then recombines when the temperature drops at the workpiece level. The recombination is an exoterm reaction which yields the heat taken at the dissociation In this way there is an additional heat gained at the level of the work piece which gives higher penetration. This happens only with bi-atomic gases (CO2).
How does a spirit level indicate level?
A bubble of air is in a small slightly curved tube of alcohol. The bubble will float at the highest point and indicate level or not level.
What are the simalarities of high and low level programming?
high level language; is a computer language that is near to human language. high level programming is a process of programming high level language.Example,c++,java,cobol are one of them. The reverse is true for the low level language.
What does high GGT level indicate?
High levels of gamma-glutamyl transferase (GGT) may indicate liver disease, bile duct obstructions, or excessive alcohol consumption. Elevated GGT can also be associated with conditions such as pancreatitis, heart disease, and certain medications. It is often used in conjunction with other liver function tests to assess overall liver health and function.
Are FORTAIN BASIC high level lenguages?
c++,java are high level language.
What does it mean when it is said that your co2 is high?
When it is said that your CO2 is high, it typically refers to an elevated level of carbon dioxide in your blood. This can be a sign of respiratory or metabolic issues and may indicate an imbalance in the body's ability to regulate CO2 levels. Monitoring CO2 levels is important for assessing respiratory function and overall health.
What does CO2 blood level of 31 mean?
A CO2 blood level of 31 mmHg likely indicates a lower than normal amount of carbon dioxide in the blood. This could be due to hyperventilation or a respiratory problem. It's important to consult a healthcare provider for a proper diagnosis and treatment.
What is the function of a CO2 sensor and how does it contribute to monitoring air quality?
A CO2 sensor measures the level of carbon dioxide in the air. It helps monitor air quality by detecting high levels of CO2, which can indicate poor ventilation or the presence of pollutants. This information can be used to adjust ventilation systems and improve indoor air quality.
Why is the CO2 level high in the atmosphere?
The CO2 level is high in the atmosphere primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release large amounts of carbon dioxide into the air, leading to an increase in atmospheric CO2 levels.
What would indicate respiration reactions are anaerobic?
Formation of CO2 and ethyl alcohol indicate anaerobic reactions.Formation of CO2 and ethyl alcohol indicate anaerobic reactions.
What does a high level of alphafoetoprotein test indicate?
High level of Alphafetoproteins (AFT) in the blood of pregnant women can indicate congenital problems in the newborn. It is not diagnostic but warrants further test. Otherwise, in men, non-pregnant women and children can indicate a form of cancer.
What does a high pH level indicate about the acidity of a substance?
A high pH level indicates that a substance is less acidic and more basic or alkaline.
What does a high potassium level indicate?
A high potassium level is an indication of hyperkalemia. This is dangerous as it may lead to changes in heart rhythm or even death.
How do you increase the level of co2 in a room?
You can increase the level of CO2 in a room by introducing more people or animals to the space, by using certain appliances that produce CO2 when in use, or by using a CO2 generator specifically designed for that purpose. However, it's important to ensure proper ventilation to prevent CO2 levels from getting too high and posing a health risk.
What CO2 level is acceptable in normal breathing?
In normal breathing, the acceptable level of carbon dioxide (CO2) in the air is typically around 0.04% (400 parts per million). In human physiology, the concentration of CO2 in exhaled air is much higher, usually around 4-5%. While elevated CO2 levels in the environment can indicate poor air quality, concentrations below 1% are generally considered safe for normal breathing.
What does a blood urea level of 59 indicate?
An abnormally high blood urea nitrogen (BUN) level may indicate damage to the kidneys and a decreased ability to properly remove nitrogenous waste from the blood in your urine.
