Visual Tests of Welded Joints Made of Thermoplastics
Journal Title: Biuletyn Instytutu Spawalnictwa - Year 2017, Vol 61, Issue 3
Abstract
The article describes visual tests of joints having varied thicknesses, made of thermoplastics and welded using a manual extruder. The research-related tests were performed following the principles specified in PN-EN 13100-1. Welding imperfections detected during the tests and the regulations of the PN-EN 16296 standard were used to identify the quality levels of the test joints.
