Checklist: plastic welding before and during work
Preparation and inspection of a plastic joint
§Before welding
- 01The material type is identified and the filler material matches it (PE to PE PP to PP)
- 02The surfaces are clean dry and prepared — PE scraped/sanded before electrofusion
- 03Pipe ends are plane and correctly aligned during mirror welding
- 04The equipment is in order and the parameters are set according to material and thickness.
§Test weld
- 01A test weld has been made on a piece of the same material
- 02The exam has been assessed — no signs of burning or insufficient binding
- 03The setting is adjusted if the test was not in order
§Before and after welding.
- 01Pressure and speed are kept even through the joint
- 02The joint is allowed to cool without load
- 03The joint is assessed visually, and a tightness test is performed if the task requires it
- 04Parameters and control
