Friction Welding Comparison

Benefits of introducing friction welding

Reduction in material and machining costs.

Compared to cutting out a part, friction welding dramatically reduces the material and machining costs.

Gives new potential to the use of dissimilar metals.

use the right material in the right place. Expandes the potential for developing new products.

Work that was difficult to machine as an integrated unit or difficult to weld by conventional methods.

can now divided by material and then joined by friction welding, simplifying the machining.

Improves yield

maintains high yields regardless of the material used. Minimizes loss.

Rationalizes upstream and downstream processes /Rationalizes the production line.

no need for upstream machining, such as cutting grooves or mating, and rationalizes the production line.

Comparison of Friction Welding and Conventional Technologies

Method Issue Effect
Arc welding
  • Insufficient precision due to heat distortion
  • Pin holes
  • Spatter and fumes
  • Emits large amounts of CO2
  • Reduces thermal effects
  • Improves work environment
  • Reduces work in process to remove spatter
  • Reduces CO2 emissions

Example of improvments through the use of friction welding

Flash butt welding
  • Insufficient joint strength
  • Heat buckling
  • Variations in joint quality
  • High joint strength
  • No heat distortion enables high precision
  • Stabilization of joint quality

Example of improvments through the use of friction welding

Solid forged part
  • High mold costs
  • Forging only some parts reduces mold costs

Example of improvments through the use of friction welding

Cutting out from solid forged part
  • Material cost
  • Equipment machining costs (Heavy cutting)
  • Product weight
  • Processing metal chips
  • Reducing material costs
  • Reducing equipment machining costs
  • Hollowing out parts to reduce weight
  • No need to process metal chips
