Common Extrusion Weld Defects
Like metal welding, plastic welding requires training and experience to become proficient. If the plastic welding procedure is not exactly right, defects can occur that will comprise the strength of the weld. Some of these defects are easily visible and others require sectioning or testing to tell if the weld is sound. Be careful not to assume a weld is strong based on how the surface looks; perform destructive tests on sample welds before you begin to ensure a good final weld.
In this article we give some of the more common defects that might be seen when welding plastics. To review proper welding technique please see our article: Using an Extrusion Welder.
