Welding, cleaning and cutting:

Fiber Laser Welder replaced traditional welding methods TIG and MIG welding.

The laser provides contact-free, high-speed metal welding solutions for advanced manufacturing.

Welding is conducted by melting the metals to create a high-quality weld.

The filler material may be required (as TIG welding).

The laser beam is tightly focused, heat input is minimized, and parts can be handled almost immediately.

• High-precision accuracy for joining small and large parts.
• It does not require skill, dexterity, or lengthy training.
• Minimum distortion due to low heat input.
• Non-contact welding – no degradation in welding quality.
• No current passes through the part.
• Weld dissimilar metals.
• Minimal maintenance.

The fiber laser welder can be used with a continuous beam for accurate cleaning to remove surface paint, coatings, and oxide layers without damaging the substrate. The substrate can be in any shape and size.

Handheld Laser Welding with Dual Channel Wire Feeder
 
Including a twin-wire feed system greatly enhances the ability to fill the wire and weld wider seams. Ascent test shows that a single-feed laser welding machine can only handle 1.5 to 1.8mm seams. However, with a double-feed laser welding machine, seams as wide as 3-4mm can be successfully welded.
 
Furthermore, this system enables fish-scale welding, ensuring a consistent welding effect without wire dragging or stuttering. With the convenience of a handheld welding control system, creating fish scale lines becomes effortless, greatly enhancing the overall welding process.

The dual wire feeder allows the simultaneous use of two different wire diameters and/or types, eliminating the need to change wire spools and related components. This allows the welding machine to switch between wire sizes or types easily.

The focal length of the laser lens in a Fiber Laser Marking Machine plays a crucial role in determining the cutting depth and precision of the marking process. Here’s how:

1. Cutting Depth: The focal length of the laser lens determines the distance from the lens at which the laser beam converges to a point, known as the focal point. The shorter the focal length, the smaller the spot size of the laser beam at the focal point, resulting in higher power density and more localized energy deposition. This allows for deeper penetration of the material being marked, leading to increased cutting depth.
2. Precision: The focal length also affects the precision and resolution of the marking process. A shorter focal length provides a smaller spot size and a narrower depth of focus, allowing for finer details and higher resolution in the marking pattern. This is particularly important for applications requiring intricate designs, small text, or high-precision markings.
3. Material Interaction: Different materials have varying absorption and thermal conductivity properties, which can affect the cutting depth and precision of laser marking. The focal length needs to be optimized based on the material being marked to achieve the desired results. For example, materials with high absorption coefficients may require shorter focal lengths to achieve deeper penetration and faster marking speeds.
4. Depth of Focus: While a shorter focal length provides higher precision and resolution, it also results in a narrower depth of focus, meaning that the distance over which the laser beam remains tightly focused is reduced. China Fiber Laser Marking Machine This requires precise positioning and alignment of the workpiece relative to the focal point to maintain consistent marking quality and depth across the entire surface.
5. Material Thickness: The choice of focal length should also consider the thickness of the material being marked. For thicker materials, a longer focal length may be preferable to ensure sufficient depth of focus and consistent marking quality throughout the material thickness. Conversely, for thin materials, a shorter focal length may be more suitable to achieve precise and localized marking without excessive energy dispersion.

Overall, the focal length of the laser lens in a Fiber Laser Marking Machine directly impacts the cutting depth and precision of the marking process. By selecting the appropriate focal length based on the material properties, thickness, and desired marking characteristics, operators can achieve optimal results in terms of depth, resolution, and quality of laser markings.

The design of a 3-piece or two-piece rigid coupling is specifically engineered to facilitate quick and easy installation, offering several features to simplify the process:

1. Split Design: Both the three-piece and two-piece rigid couplings are split into multiple segments, typically two or three pieces, allowing them to be easily opened and placed around the pipe joint. This split design eliminates the need to slide the coupling over the end of the pipe, streamlining the installation process.
2. Hinged or Interlocking Design: Some two-piece rigid couplings feature a hinged design, allowing the two halves of the coupling to swing open like a clamshell. Others may employ an interlocking mechanism that allows the segments to snap together around the pipe joint. This design feature makes it easy to position the coupling on the pipe without disassembling the entire coupling.
3. Bolted Closure: Once positioned around the pipe joint, the segments of the coupling are secured together using bolts or screws. The bolted closure ensures that the coupling remains securely fastened during installation and operation.
