Whether part of a DIY project or industrial operations, most welding processes use high-quality industrial gases. They’re often used for shielding or protecting the weld pool from contamination by other atmospheric gases, dirt, and debris.
Indeed, a steady supply of inert gases like argon, helium, carbon dioxide, and nitrogen can determine the success of welding projects.
These specialized gases don’t come cheap so it’s essential to ensure that they’re used optimally and effectively.
How can you get the greatest value from your investment?
Here are some tips that can help you control the amount of shield gas you use without compromising the quality of your work.
Tip 1: Keep Track of Your Flow Rate
The first step is to determine exactly how much gas you need for a welding project and how much gas is wasted in operations.
Setting the right flow rate is a crucial step for optimizing your gas usage. Remember that thinner materials require a lower flow rate than thicker ones. Similarly, manual tasks require lower flow rates than automated tasks.
An improper flow rate not only increases your gas expenses but also leads to lower-quality welds.
Tip 2: Maintain Gas Surge
A gas surge occurs every time you hit the nozzle of your welding torch. In the long run, this can waste a large amount of precious resources. A gas surge can also pull excess air into the weld zone which is full of moisture. This can lead to welds of inferior quality.
There are several devices that can help prevent gas surges, including fixed-flow adapters and surge protectors.
Tip 3: Plug the Leaks
Leaks in gas delivery systems are very common and can lead to massive losses if they are left unaddressed. One of the easiest ways to detect leaks is by shutting down the system completely and checking back in a day or two.
If there is a discrepancy in the levels, there’s a good chance that a leak may be the culprit. With a proper leak detection system in place, you could end up saving big on gas costs.
Tip 4: Use the Right Gas Blend
Different welding processes and materials require their own unique blend of gases to work optimally. In the oxyacetylene welding process, for instance, the ratio of oxygen and acetylene produces different results — a higher amount of oxygen makes the flame hotter, while acetylene serves as fuel. Familiarizing yourself with various welding processes and blends can go a long way in maximizing your gas usage.
