Why Is an Inert Shielding Gas Required for GTA Welding?

Inert shielding gases are required for Gas Tungsten Arc Welding (GTAW) to protect the weld pool and tungsten electrode from atmospheric contamination. Without these non-reactive gases, oxygen and nitrogen would compromise weld integrity, which could lead to defects and weakened joints. In this article, we’ll explore the main reasons why you need inert gases in …

Is Argon Toxic?

Argon is not toxic, but it can be dangerous due to its potential to displace oxygen in confined spaces. While it presents minimal chemical risks as it’s highly inert, it poses a significant asphyxiation hazard.  In this article, we’ll explore how argon affects the human body in more detail. We’ll also discuss the conditions under …

What Is Industrial Oxygen?

Industrial oxygen is a highly purified form of oxygen gas (typically 90-99% pure) used in manufacturing, metalworking, and chemical processes. Unlike medical-grade oxygen, industrial oxygen is not subject to FDA regulations for human consumption and is specifically manufactured for technical applications. In this guide, we’ll explain how industrial oxygen is produced and cover its main …

What Gases Are Used in Meat Packaging?

The most commonly used gases in meat packaging are carbon dioxide (CO2), oxygen (O2), nitrogen (N2), and sometimes carbon monoxide (CO). These gases are combined in specific mixtures through a process called Modified Atmosphere Packaging (MAP). In this guide, we’ll explore how these industrial gases work together to preserve meat while meeting industry standards and …

What Is Reduced Oxygen Packaging?

Reduced Oxygen Packaging (ROP) is a food preservation method that removes or reduces oxygen from food packaging to extend shelf life and maintain product quality. It creates an environment with oxygen levels below 21%, which inhibits the growth of aerobic bacteria, yeast, and molds that cause food spoilage. In this article, we’ll explain how reduced …

What Is Medical Grade Oxygen?

Medical grade oxygen is a pharmaceutical-grade gas that typically contains at least 99.0% pure oxygen, though USP standards allow for certain medical applications to use oxygen concentrations between 90% and 99% at the bedside.  It must meet strict FDA regulations and include severely limited contaminants to ensure patient safety. Unlike industrial oxygen, medical grade oxygen …
