Laser Welding is easily recognised by its' exceptionally uniform and fine joints. Lasers are excellent for welding thinner materials, hermetically sealed joints, or welding in close proximity to heat-sensitive components thanks to the minimal Heat Affected Zone of the process compared to conventional welding methods.
The laser also excels for hard-to-reach spots as long there is a free line of sight between the nozzle and weld area.
Laser welding can be done in virtually all conventionally weldable materials, but also typically incompatible materials like high-carbon Stainless Steel and Titanium, among many others.
LMI AB has a Long History of Designing Tailored Laser Welding Solutions, Ranging From Micro-Scale Medical to Large-Scale and Volume Automotive Industries. Below are Some Examples of Custom Systems We've Built.
We have a Wide range of high-power lasers from 500W - 12kW and specialised equipment with pulsed Nd: YAG lasers for welding thin materials and production of hermetically sealed joints.
The birth of the LMI CLW 1000 machine concept resulted from our customers' need for a compact and user-friendly heavy-duty ABS ring welder with short cycle times.
Its minimalistic control panel and custom-made GUI makes this welder an extremely operator-friendly turnkey welding package. When equipped with an IPG fiber laser up to 2 kW, the air-cooled laser source can be installed inside the Class 1 protective cabinet. The result is a very compact independent turnkey system that can be fitted with any fixture or tooling to fit the need of many customers
ST2000 Laser welder
The Mini-FlexPro® Laser Welding workstation is a platform LMI has used several times for custom welding systems, and can be fitted with up to 7 axis.
Hybrid Laser welding
Hybrid laser welding is a combination of the more Conventional MIG / MAG technique and laser processing. The intense energy delivered by the laser in combination with an Effective melting of the MIG / MAG welding wire results in high-speed welding That can bridge large gaps between surfaces.
The process Provides significant advantages Compared to MIG / MAG Merely by the fact That it is given a much lower distortion and can be reunited with Gina sweep Components That Reduce cycle time and avoid rework. Common hybrid welded materials include aluminum alloys and carbon steel.
Remote welding - galvo controlled laser welding
Remote welding or galvo based welding differs from traditional laser welding by the fact that the workpiece does not have to move, instead the beam is guided by the two moving galvo mirrors inside the scanner. Small movements of the mirrors leads to large movements of the focused beam, resulting in beam velocities of 500 ips (13 m / s). Remote welding is typically used for thin or sheet materials that require a series of stitches or points to be strong enough.
The galvos rapid and precise positioning of the beam between the welds significantly reduces the total cycle time. Process area (or field of view) varies but can be as large as 1 x 1m. With applications ranging from spot welding of electronic devices to joint welding of sheet steel for cars.
Advantages of laser welding
Minimal heat input, provides a small heat-affected zone (HAZ)
Fine-grained treatment with exceptional welding quality
High energy density and high welding speed
No filler material required for most applications
Welding in hard-to-reach areas
Our partners provide experienced application engineers to help to create a process for welding Normally Incompatible materials. LMI AB is capable of performing metallurgical evaluations and our staff is experienced in destructive and non-destructive techniques (eg. ultrasound, x-ray, helium leak detection) for Assessing weld quality.
We're experienced in hybrid and induction assisted laser welding as well as cold wire fed welding. Sometimes, this is a necessity if the weld chemistry requires changes to meet the design requirements.
