BE-15 Pipes and Materials: Welding of Plastic Pipes

Factors of influence on the welding quality

Residual welding stresses

Residual welding stresses are inevitably caused by the following factors:

  • Flow and diversion current during the welding procedure and
  • Shrink stresses during the cooling process

Residual welding stresses are considerably increased by non-observance of the right welding parameters or environmental effects.
