What You Should Never Do When Cutting or Welding

When you're heating things up with a welder or cutting tool, safety has to be at the forefront of your mind. You must know what to avoid when you're in the thick of it, right? Understanding what should NEVER be done while cutting or welding is critical for any student or professional aiming to pass the AWS Welding Inspection and Testing Certification. So, let’s break down some of the cardinal rules.

Concrete: A Hidden Hazard

You might think concrete is a strong and durable material, and while that’s true, it can become a nightmare if you start welding directly against it. You’ve probably heard about heat-related damage, but do you know about spalling? It’s when the surface of the concrete cracks and breaks away due to intense heat. That’s a safety concern and a structural compromise rolled into one. It’s like driving a spike through the foundation of a house—definitely not a good idea.

Welding against concrete is not just about the heat, though. What if I told you that concrete can hold moisture? Yep! When that moisture heats up, it turns into steam and—surprise!—you get a steam explosion. No thanks! You want to avoid those types of surprises when you’re working. It’s a classic case of “better safe than sorry.”

Material Matters
But wait, let’s take a step back. What about other materials like steel, wood, or even aluminum? While these also carry their own risks, they don’t present the same kind of dangers when welded or cut properly. With steel, for instance, you have the added strength and resilience that can be negotiated with proper technique.

You know what’s interesting? Wood can even be a better alternative if you’re mindful of using the proper methods and equipment. It's all about understanding the materials you’re working with and their individual properties. Each material has its quirks and those quirks can affect your welding experience.

Stay Safe Out There!
In wrapping things up, one of the most important lessons in welding and cutting is learning the do's AND don'ts of your craft. By steering clear of welding against concrete, you're not just protecting yourself; you're also preserving the integrity of the project at hand. Always stay informed about the materials you’re working with. Knowledge is power, especially in a field where safety is paramount!

So, as you get ready for your AWS Welding Inspection and Testing Certification, keep this in mind: welding is an art, but it’s also a science. The best welders blend technical precision with an instinct for safety. Are you ready to step up your welding game? Let’s do this!
