Jaco Machine Works is excited to announce our new in house laser welding capability with the company’s LaserStar® G3 1900 pedestal laser welder.
Laser welding is particularly useful in the Aerospace and Medical Device industries due to its advantages over similar types of welding such as TIG. Laser welding is fully automatable, allowing high production runs to be completed with very low variation.
Welding is a very common metal joining process in which adjoining components are heated to their melting temperatures forming a small pool of molten metal in the joint. As the metals cool, the parts fuse together, forming a very strong, permanent bond. The most common welding processes include:
- SMAW (Shielded Metal Arc Welding)
- GTAW (Gas Tungsten Arc Welding, aka TIG)
- GMAW (Gas Metal Arc Welding, aka MIG)
- Oxy-Fuel (uses the combustion of Oxygen and Acetylene to heat the workpiece)
- Laser Welding (which uses a laser to heat the workpieces).
Lasers use a concentrated beam of light that is coherent (in phase, same wavelength, travelling in same direction), collimated (contained in a beam with a very small diameter), and monochromatic (one color). This means Lasers apply heat to the workpieces in a highly focused small area. Laser welding is particularly advantageous in the Medical Devices and Surgical Instruments, especially where high precision, minimal heat warpage circumferential welds are necessary.
Engineers looking for highly precise, circumferential welds with minimal heat warping for long, slender medical device parts prefer laser welding.
Jaco Machine Works provides in-house laser welding capabilities and services with our LaserStar® G3 1900 Pulsed Nd:YAg pedestal laser welder. The G3 1900 can produce up to 80 Joules of heat, pulsing from 0.5 – 20 Hertz with a pulse length of 0.2 – 20 milliseconds.
Benefits of Jaco’s Laser Welding Capabilities:
- Automation: Workpieces are mounted into a programmed rotary motion device. Circumferential welds of slender components can be accomplished with astounding repeatability.
- Precise Control: A power monitor kit is employed to ensure the correct amount of energy is put into each weld, and immediately notifies personnel of discrepant welds.
- Precision Welds: Stereo microscope coupled with a precise Beam Expander provides precise control of the beams focal point, enabling extremely small heat zone, which further increases weld consistency.
- Minimal distortion: Highly focused and pulsed beam produces clean welds with minimal extra heat added. Less heat means results in less distortion and warping of the joined components.
Laser welding is particularly effective when paired with a highly robust quality system, such as Jaco’s. Whatever your application may be, Jaco Machine Works’ engineers and talented operations professionals are determined to help you succeed.
