Fiber laser welding is a process that uses a laser beam to melt and fuse metal parts together. The laser beam is delivered to the workpiece via an optical fiber, which is why it is called a “fiber” laser. The beam is focused on a very small spot, creating a high-energy density that melts the metal. The metal cools and solidifies, forming a strong bond between the parts.

Fiber lasers have several advantages over other types of lasers for welding, such as CO2 lasers. They have a higher power density, which allows them to produce a smaller and more precise weld. They also have a higher beam quality, which results in a more consistent and uniform weld. Additionally, fiber lasers are more efficient and have a longer lifespan than other types of lasers.

Fiber laser welding is used in many industries, such as aerospace, automotive, medical, and electronics. It is particularly useful for welding thin materials, such as sheet metal and wire, and for welding difficult-to-reach areas.

It is important to note that fiber laser welding require special training and safety precautions. The intense light emitted by the laser can cause damage to the eyes and skin, and the heat generated by the process can cause burns and fires.

LightWELD – Less Heat & Distortion for More Productivity & Flexibility

TIG welding is a time-consuming, two-handed welding method that requires an experienced, highly-skilled operator. TIG welding may generate extreme heat that deforms thin materials, produces poor visual finishes, is difficult when welding copper, and limited when welding metals of dissimilar thicknesses.

MIG welding requires consumable wire, material pre-cleaning and beveled joints for thick metals for full penetration.  Travel and work angles are limited and vertical positions are extremely challenging.

LightWELD enables dramatically faster welding, is easier to learn and operate, and provides higher-quality, consistent results across a wider range of materials and thicknesses than MIG or TIG with minimal distortion, deformation, undercut or burn-through.
The low heat input and extensive material and thickness capabilities increase productivity, repeatability, and improve weld quality for operators of all skill levels. LightWELD welds dissimilar metals of different thicknesses with ease and creates aesthetic high-strength joints with minimal or no consumable wire. Plus, LightWELD XC and LightWELD XR offer built-in pre- and post-weld cleaning not found on any traditional system.

LightWELD is Fast & Easy to Set Up

  • Ergonomic, compact and proven to be the most comfortable and easy to use laser gun with built-in wobble welding functionality.
  • 2-step trigger and part contact sensor enhance operator safety
  • Purpose-built nozzle tips for various weld joint types and pre and post weld cleaning applications
  • Quickly switch from standard laser welding to wire welding, and from laser welding to laser cleaning
  • A single cable from the unit delivers laser power, gas and control connections to the gun

LightWELD – Factory Presets Ensure Optimized Welds & Cleaning

  • Simple preset selection ensures consistent high-quality laser welds and cleaning
  • Presets include wobble welding function to accommodate wider seams and for parts with poor fit-up
  • Operators can instantly switch between presets to process multiple material-thickness combinations
  • Advanced operators can customize presets, save for future use and can be used by novice operators to produce the same results
  • Novice operators require less training which reduces labor costs while preserving quality, increasing productivity and decreasing scrap
