Laser sources for the metal working industry

Specific laser sources for specific jobs

Technological Evolution and innovation are often signs of market demands: today there is a real interest in laser applications which become increasingly involved in metal working industry. 
The most used sources for metal working lasers today are following 3 groups of laser sources:
=>crystal/fiber optic lasers (YAG and Fiber Lasers), and
=>solid state lasers (diode lasers, disk lasers and DPSS lasers).

Laser Welding

Laser Welding Solutions and Advantages

Laser welding is one of many industrial laser processes and is used to join various materials together by creating a strong weld between them. This process can be used to create a strong and permanent joint between two types of material. The laser being used focus a beam of high-intensity light on a desired area. The aim of the laser welding process is to physically melt the two materials together to form a bond between them. Although such technology is mostly used to join metals, it can also process other type of materials such as plastics and silicone.

Laser welding method provides ultimately precise heat input to the desired area with narrow full penetration weld which makes an aesthetic final result with close to zero welding oxidation. When thin large sheets are joined, laser welding (in many cases) is the only welding method to avoid thermal and physical distortion of the end product without additional processing. Laser welding is the best welding method to minimize loss of base material properties, such as hardness and strength. The laser joining process can be used in both: hand held precise small jobshops and large-scale automated workshops, allowing welding speed of 1-5m/min. Laser welding is over 5 time faster than MIG and over 10 times faster to TIG. Low waste and simple maintenance makes this technology user and environmentally friendly.

  • Close to zero physical distortion – when thin large sheets are joined, laser welding avoids thermal and physical distortion of the end product without additional processing.
  • Low welding oxidation – Fiber laser welding method provides ultimately precise heat input to desired area with narrow full penetration weld which makes an aesthetic final result.
  • Excellent mechanical properties – laser welding does not affect material or its structural properties.
  • Easy to operate even for weld beginners – due to laser welding memory of set up parameters.
  • Very high efficiency – laser welding is >5 times faster than MIG and >10 times faster to TIG.
  • Long and wide sheets welding
  • Cost efficient welding solution – low energy consumption.
  • Allows welding of sheets with different steel grades and dimensions.
  • Relatively high single-time investment costs compared to traditional methods.
  • Standard Fiber laser welding requires a tight fit between the parts to be joined, which is not the case with our wobble laser welder.  In many cases it is best to redesign the joint locations to present overlapping surfaces for normal fiber lasers, but our wobble laser can handle none tight fit connections..
  • Limited material thickness (today’s maximum 10mm single sided).
