The advantages of laser welding machine

The advantages of laser welding machine.

The heat required for welding is supplied by a tightly focused light beam.That with a diameter as small as two-thousandths of an inch. Welding is conducted by firing a series of short pulses that melt the metal to create a high-quality weld. Depending upon the particular welding task, filler material may be required as with TIG welding. Because the laser beam is tightly focused, heat input is minimized and parts can be handled almost immediately.

The advantages of laser welding machine.

• Weld strength: The laser weld is narrow with an excellent depth-to-width ratio and higher strength.
• Heat affected zone: The heat affected zone is limited, and due to rapid cooling, the surrounding material is not annealed.
• Metals: Lasers successfully weld carbon steel, high strength steel, stainless steel, titanium, aluminum, and precious metals as well as dissimilar materials.
• Precision work: The small, tightly controlled laser beam permits accurate micro-welding of miniature components.
• Deformation: Parts have minimul deformity or shrink.
• No contact: No physical contact between the material and laser head.
• One sided welding: Laser welding can replace spot welding requiring access from one side only.
• Scrap: Laser welding is controllable and generates low volumes of scrap.

Applications

The unique properties of laser welding give it a significant advantage over other forms of welding that can be exploited in several ways:

• Precision parts: Lasers are excellent for welding fine and delicate metal components and generating minimal internal stresses due to the minimal heat input.
• Medical devices: Non-contact welding and no welding splatter ensures hygiene when welding medical devices.
• Solenoids and machined items: Lasers are ideal for joining machined components such as solenoids, and create minimal distortion due to the low heat input.
• Aesthetics: Laser welding finishes are excellent.
• Limited access: The non-contact laser beam permits welding in otherwise inaccessible areas.
• Jewelry welding and high value items: The precise controllability and negligible heating effects make it a good choice for welding high value, high precision parts including precious metals.
