The Laser welding process offers the most flexible and versatile metal joining process in today’s manufacturing environment.

A Laser (Light Amplification by Stimulated Emission of Radiation) delivers a concentrated heat source at a relatively short time duration resulting in narrow, deep welds at a high rate. The process has been adopted by many industries such as medical device manufacturers, automotive, jewelry, plastic injection mold makers, electronics, and dental laboratories to name a few.

Laser welding has many advantages over conventional welding processes such as TIG, MIG, or electron beam welding (EBW). Laser welding produces minimum heat-affected zones (HAZ). In addition it can generate high rates of heating and cooling so very thin materials can be processed without deformation or warping.

Another advantage is that laser welding beam can be transmitted through ambient air rather than requiring a vacuum or inert gas shielding environment resulting in a very clean and high quality weld.

Today’s Laser welding machines are capable of welding both similar and dissimilar metals in addition to most industrial alloys and  high reflective metals such as copper, silver, and gold and less reflective metals such as tool steel, stainless steel, titanium, platinum, and palladium.

Ringtech is proud to announce our collaboration with Z-Tech Advanced Technologies

Our QM Series lasers can deliver precise cut parts with thickness up to 5 mm from commercially available sheet metal.

Z-Tech’s QM Series processes Gold, silver, platinum, stainless steel, nickel, molybdenum, titanium, brass, and copper with a repeat accuracy of ±5µm and radius of 16 µm. The laser cutting process eliminates any additional tools necessary in conventional cutting and allows the production of small to medium batches economically feasible. Even single pieces are cost-effective for one of prototypes.

Advantages of Laser Cutting Technology

  • Flexibility: contour cutting directly from DXF, DWG, SVG or stl files
  • Precision with high degree of edge steepness without reworking
  • Minimal thermal or mechanical effects on cut parts
  • Cost-effective even for short runs
  • High level of repeatability and accuracy
  • Zero tool cost
  • Any form or contour is possible
  • Parameters for broad range of materials available

  • Clean cut edges with minimum burr or dust formation
  • Cutting of extremely fine contours and practically radius-free inner edges
  • Cutting of various material thicknesses and combinations in one operation.
  • No fixtures or protective gas cover, or coating are necessary.
  • High level of precision and positional accuracy of the cut edges.
  • Ability to cut ultrathin foil
  • Ability to engrave and cut in 2D, 2.5D and 3D.
