What Does "4+2" Mean in the Laser Welding Industry? And What is a "Ring Spot"?

Hello, everyone! Welcome to our quick guide on the fascinating world of laser welding technology. Today, we’ll dive into a topic that often leaves people scratching their heads—what exactly is "4+2," and what’s this "ring spot" all about? Stick around, and by the end, not only will you understand these concepts, but you’ll also be able to impress your peers with some industry know-how over lunch!

What is a "Ring Spot"?

Let’s start by breaking down the first concept: the "ring spot." In simple terms, this is a laser beam shaped like a donut, with no light in the center and light concentrated around the edges. Think of it as a "light donut." When used in welding, it can heat multiple points simultaneously, resulting in a more uniform energy distribution. It’s smarter and more efficient than a traditional spot laser.

The ring spot is particularly well-suited for precision manufacturing, such as sealing in new energy battery production or welding high-quality electronic components. Its hallmarks? Precision, stability, and reliability.

Why Choose a Ring Spot for Welding?

You might wonder: "Isn’t traditional laser welding good enough?" Sure, it works—but in the industrial world, "good enough" rarely cuts it. Traditional laser welding can overheat certain areas, leading to issues like deformation, porosity, or cracking—basically, a recipe for frustration.

The ring spot, however, acts like a skilled designer, optimizing heat distribution. Here are its standout features:

1. Smarter Heat Distribution

By heating multiple points evenly, the ring spot minimizes welding stress and reduces deformation. For applications requiring a "like-new" appearance after welding, the ring spot is a game-changer.

2. Greater Welding Adaptability
It’s forgiving of minor surface imperfections. Slight oxidation or uneven surfaces? No problem. It’s efficient and dependable.

3. Top-Tier Weld Quality

The welds are both aesthetically pleasing and structurally robust, with no cracks or pores. Whether it’s strength or appearance, the ring spot delivers premium results.

What Exactly is "4+2"?

Now for the main event: "4+2." This term refers to a highly advanced laser configuration in ring spot welding. Translated, it means a 4-kilowatt ring spot laser paired with a 2-kilowatt point spot laser.

Breaking Down the 4+2 Setup

4-kilowatt laser: Outputs the ring spot, providing wide-area heating to ensure uniformity and stability in welding

2-kilowatt laser: Focuses on localized deep reinforcement, delivering extra power where it’s needed most.

Why is this Combo So Effective?

Complementary Functions: The ring spot lays the groundwork, while the point spot adds precision, effortlessly handling complex welding tasks.

Precision Power Control: The 4-kilowatt laser covers larger areas, while the 2-kilowatt laser hones in on the details, reducing waste and increasing efficiency.

Versatile Applications: Whether it’s large-scale joining or intricate detail work, this combo excels in a variety of scenarios.

The Future of Ring Spot + 4+2

This dynamic duo is already making waves in high-tech industries like new energy vehicle batteries, electronics packaging, and medical devices. For example, in battery welding, the ring spot ensures even preheating, while the "4+2" configuration precisely manages welding intensity, resulting in longer battery life and higher quality.

In Summary: Cutting-Edge Tech Shaping the Future of Manufacturing

The buzz around the laser welding industry wouldn’t be the same without "4+2" and the ring spot. These innovations address the limitations of traditional processes, making production faster and more precise. From smart manufacturing to renewable energy, these technologies are set to play an indispensable role.
