Quality of plastics constructions

During the construction of plastics constructions, the quality of the welded joints is crucial. The quality of the adhesion of the welding surface can be ensured by a number of measures:

  • Control of preparations and welding parameters before the start of the welding process
  • Control during the welding process
  • Visual and mechanical examination of the fabricated welds after the welding process
