Can nitrogen be used to purge gas pipes before welding?
Yes, and No, Nitrogen can be used to purge gas lines prior to welding, but the correct answer depends on several things, mainly, your welding application. A significant amount of resistance welding applications use N2 as a suitable environment for welding. Other applications use N2 as a purge gas, and then purge the N2 with the process gas. That said, if you were going to be using a different inert gas (Argon, Helium, Xenon, etc.) to provide the actual the actual shield for the weld, then you would still need to displace (purge) the N2 from the lines. The last statement leads to the question of; if you are going to have to purge the lines anyway, why do it twice? The answer to this question is pretty basic. Nitrogen is cheap. If you had to purge a lot of lines, or a large volume of space, you would rather use N2 to drive out the Oxygen and lower the dew point (moisture). Using one of the other welding gases would cost about ten times as much to perform the operation.
What is the welding cert roster code for welding?
roster welding
Name of the type of welding?
One type of welding is tube welding. Another type if mig welding.
Difference between ERW and SAW welding?
SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
What are smaw welding?
smaw welding is sheilded metal arc welding
Does Home Depot sell liquid nitrogen?
No. You can get it at a welding supply store.

Explain the role of a clover in the nitrogen cycle?
The role of clover in the Nitrogen cycle is to pull Nitrogen from the air back into the soil.
What is the role that nitrogen plays as essential to the production of proteins?
the role of bacteria in nitrogen fixation
What is the role of nitrogen plays as essential to the production of proteins?

What organisms play a role in the nitrogen cycle?
Producers (incorporate it into organic) and bacteria play a major role in the nitrogen cycle.
What is a plant's role in the nitrogen cycle?
Plants consume nitrogen in the form of Nitrates. Nitrogen gets converted into nitrates by the denitrifying bacteria. These plants absorb nitrogen in the form of nitrates through the groundwater.
Role that nitrogen plays as essential to the production of proteins?
Nitrogen is a key element. Proteins contain nitrogen and without nitrogen no protein.
What role does nitrogen provide to the human cell?
Nitrogen is normally not used by the human cell.
What is the role of nitrogen fixing bacteria?
they help balance the level of nitrogen in the soil and atmosphere.
What is the role of nitrofying bacteria?
Convert gaseous Nitrogen into nitrogen compounds.
