Fiber Laser Welding: Everything You Need to Know - DENALIWELD

Welding requires a high-power heat source to fuse workpieces. Amongst various options available today, fiber lasers are one of the fastest and most precise.

For this reason, fiber laser welding has gained prominence across modern industries such as automotive, aerospace, and manufacturing.

Can fiber laser welding propel your production speed and efficiency? Read on as we discuss this innovative welding technique and its vast applications.

Fiber laser welding uses optical fibers doped with rare-earth elements like ytterbium to convert light into laser beams. The laser diodes convert electrical energy into light, then a coupler combines the light generated by the diodes to form a coherent and intense beam of light.

The concentrated beam is then focused onto the workpiece and melts metal with an average penetration speed of 0.8 inch per second. The workpieces are then fused on cooling.

Many manufacturers realized the impact of fiber laser welding on their daily operations. Its unmatched precision and efficiency over traditional methods make it an optimal choice to streamline production processes.

Here are some reasons why firms choose fiber laser welding.

The ultra-precise beams of fiber laser welding keep a minimal heat-affected zone on the workpieces. Hence, it is easily applicable both with thick and thin metals, non-metals, thermoplastics, and even organic compounds.

Fiber laser welding also supports the fusion of dissimilar metal workpieces because of its controlled heat input that prevents metallurgical issues and thermal distortion.

Manufacturers in the electronics, medical, aerospace, and jewelry industries make tiny parts that need meticulous welding to keep quality high. Amongst welding techniques, fiber laser welding is the one with the highest precision at a micro level which is crucial for the aforementioned industries.

Moreover, most fiber laser welding machines are designed to focus and melt only specific portions of a workpiece. So, using this welding technique translates to a small heat-affected zone which means more consistent and cleaner welds.

Unlike traditional methods with a steep learning curve to master, fiber laser welding is more beginner-friendly. A fiber laser welding machine typically has an intuitive interface or control that enables quick and easy adjustment of laser power, speed, and focus. Hence, an employee with zero experience can be proficient with this welding technique after a few training sessions.

While MIG and TIG are reliable welding methods, they often produce coarse-grain microstructure because of their limited power input. Thus, MIG and TIG joints are typically vulnerable to cracking or material defects when under stress.

Meanwhile, fiber laser welding’s highly concentrated beams are strong enough to create localized heat-affected zones with fine-grain microstructure. This results in stronger welds that can withstand stress over time.

Estimates indicate that fiber laser welding is about three to ten times faster than the traditional methods because of its highly concentrated beam and high power input.

And since fiber laser welding ensures minimal thermal distortion, manufacturers may not perform post-welding clean-ups, which speeds up the production process.

Even with minimal maintenance, a fiber laser welding machine can operate long-term with consistent performance. It only requires regular cleaning and software updates to ensure it is in good shape.

And since fiber laser welding can fast-track the production process with its impressive penetration speed and accuracy, it drives down the manufacturer’s operational and labor costs over time.

The impressive accuracy, speed, and strength of fiber laser welding make it an ideal choice for many manufacturers in these industries.

Automotive: Fiber laser welding aids in the production of engine components, transmission parts, gears, and fuel injector nozzles. It can also effectively combine steel panels in the car body, roof, or hood.

Electronics: Highly reliable in welding small, intricate pieces such as microchips, connectors, and sensors. It can also assemble metal compact components in smartphones, tablets, and computers with minimal thermal distortion.

Aerospace: Weld turbine blades, combustion chambers, and other structures that require strong and precise joints to enhance the aircraft’s safety and performance.

Medical Device and Equipment: Due to its capability to fuse workpieces with minimal contamination and defects, fiber laser welding is crucial to the construction of various medical tools like surgical equipment, endoscopies, dental implants, orthopedic devices, and steel prosthetics.

Reasons To Buy From Us - Quality, Service, And More

Why World Diamond Source Offers The Best Value In Diamond Saw Blades
Rising from the humble origins of a small rented office nearly 26 years ago, family owned and operated World Diamond Source® (WDS) is now the industry leader for factory-direct diamond saw blades, core bits, concrete polishing tools, and all other types of diamond tooling. Here are 10 reasons why WDS is the contractors’ go-to supplier:

1. Higher Quality = More Value.

Performanceminded contractors always look at the cost per cut from their diamond blade. Buying strictly on dollars alone is a false economy. They know it makes no sense to buy 10 $100 tools when three $250 tools can get the same job done at 25 percent savings.

2. Factory Direct Pricing.

WDS built its business by offering factory-direct savings, cutting overhead on the industry’s most comprehensive selection of blades. No one offers a better combination value, service, trust, and savings as WDS.

3. Platinum-Level Customer Service.

Contact WDS and you’re in touch with a trusted diamond tooling advisor with the expertise you need to get maximum value from your diamond tooling purchase. What are you cutting? What’s the task? Our people take the time to understand your needs, offering you the best values in the market.

4. Licensed, Insured Supplier.

Why bet your project safety and performance on a questionable supplier? For nearly 26 years, WDS has reduced the cutting costs of more than 25,000 contractors, from sole proprietors to the industry’s largest commercial businesses. “Building relationships that last” is more than a WDS company motto. It’s how we earn your business.

5. “The Proof Is In The Pudding.”

Put a WDS blade on your saw for 30 days at our risk. If the WDS blade kicks butt, all we ask is you pay for the blade. It’s our way of proving ourselves in the only test that matters, your jobsite. Who else invites you to try before you buy?

6. “OMG” Inventory And Delivery Speed.

Why expose your project to needless downtime? The WDS warehouse is packed with nearly $4 million in blades and surface preparation tooling.

7. Continuous, Relentless R&D.

WDS’s research and development program is led by the man that also runs WDS, Cliff Maddock. As a familyowned and operated business, Maddock is able to innovate and respond to industry trends on the fly, providing WDS customers with the latest, highest-performing blade technology across all cutting categories.

8. Our Manufacturing Processes.

Anyone can copy a WDS blade design. But no one outside of WDS understands the manufacturing process that went into forming that blade. That proprietary process of manufacturing and bonding is a closely-guarded method that differentiates WDS blade performance from poorperforming knock-offs.

9. FREE Catalog.
