Testing
Testing of welded joints in compliance with current standards
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
