Welding Steel Cutting Seat Belts Marking Electrical Components

SYNRAD's sealed CO2 lasers are used in a variety of industrial processes including cutting, welding, drilling, and marking. This news brief showcases some of the interesting materials and products that are processed daily by Synrad's line of CO2 lasers and marking heads.

Welding Steel

   This two-part flange assembly consists of a 316 stainless steel section and an Inconel steel section. The two sections were hermetically-welded together using 240 watts of power, delivered through a 2.5" focal length positive meniscus lens. Argon was used as a shield gas to protect the weld area from contamination as the part was rotated through the beam path (0.004" diameter spot size) at 28 inches per minute (IPM). Rotational speed and laser heat input into the flange produced a weld bead approximately 0.065" wide. Although bolts supply the mechanical strength of the completed flange, the weld withstood both a 2,000 PSI water burst test and an 800 PSI Helium leak test after assembly.

These stainless and Inconel steel flanges, with
inside diameters of 2.25", were hermetically-welded
using an Evolution 240W CO2 laser.

Cutting Seat Belts

 

    Like most synthetics, laser cutting of this nylon seat belt webbing resulted in clean cuts with a sealed edge. The cuts were made at a speed of 210 IPM using 100W of power and 10 PSI air assist. The Firestar f100 beam was focused down to a 0.004" spot using a 2.5" focal length lens which provided a 0.07" depth of focus.

Marking Electrical Components

 

   Lasers are ideal for adding identifying marks to small parts. The two-line, ten-character mark (0.07" high stroke text) was marked on this electrical component using 10W of laser power at a marking velocity of 25 inches per second in a cycle time of 0.13 seconds. The CO2 beam was steered using an FH Series Marking Head and focused through an 80 mm flat-field focusing lens, which provides a 116 micron focused spot.
0.07"-high text was marked on electrical
components using a Synrad 48-1 CO2 laser.
