Laser welding is a high-energy process in which a focused laser beam is used to melt and join workpieces. Laser welding can be performed with or without filler material. 

 Advantages

 Laser welding provides a number of advantages over more traditional joining methods:

• Faster welding speeds 
• Minimal heat input and distortion
• Very high-quality and reproducible welds
• Possible to weld complicated geometries
• Narrow and deep-penetration welds are possible
• Possible to weld parts of dissimilar thicknesses
• Possible to weld special combinations of materials
• The laser beam can be transported in an optical fibre.

 The above-mentioned capabilities also provide a number of economic advantages: 

• Higher productivity
• Increased flexibility
• Possible to weld close to heat-sensitive components
• Simplified joint design
• Automated welding machines or robots can be used.

 Working together with the FORCE Technology, you have 

• a partner with 15 years of experience in the industrial applications of laser welding;
• assistance in development projects and consultancy in part design and the purchase of advanced equipment;
• access to Scandinavia’s largest and most flexible laser installation, which includes a number of beam delivery and positioning systems using both CO2 and Nd-YAG lasers and which can handle a wide variety of applications in welding materials of thicknesses varying from foil to heavy goods;
• the opportunity to perform pilot production runs at our workshop.

 Applications

Laser welding can be used in production processes in which a high productivity combined with flexibility is desired without compromising on quality.

A high and uniform quality with a low heat input makes this process suitable for a wide range of applications in which components are sensitive to heat or minimum distortion is desired. 

Examples of industrial laser welding applications:

• Engineering and manufacturing
• Shipbuilding and repair
• The automotive industry
• Medical equipment
• The electronics industry

FORCE Technology services

The FORCE Technology can provide consultancy services all the way from idea to finished product. With the enormous volume of expertise and experience we have at our disposal, we can help optimize your entire production process. Typical jobs for the FORCE Technology are 

• process development in connection with new products
• design review of new or existing products
• optimization of materials and joining methods
• production process optimization
• testing and documentation of product characteristics
• consultancy in connection with implementation of equipment
• prototypes made and pilot production runs in our own workshops
• courses in laser techniques

Documentation

Documentation can be provided as required by the client. Normally, we prepare a WPS containing the relevant process data. Quality and weld geometry can be documented by macroscopic analysis of samples, mechanical testing or non-destructive testing.
