Extrusion welding checklist
Extrusion welding checklist-a definitive guide
Before you begin
- Check that there’s enough extrusion rod for the job
- Clear the welder of any old material
- Doublecheck that the shoe matches the seam you want to make
- Scrape away the oxidation layer on the PE pipes
- Clean the surfaces of any mud, dust, oil, water, etc
- Set the pipes in place – tack weld or clamp
- Set the right temperature for the extrusion rod you’re using
As you weld
- Preheat the surface where you’ll start welding
- Check the angle of the welder. (How well is the extrusion following? Are the surfaces preheating evenly? Does your seam look straight and regular?)
- Balance your travel speed against the extrusion rate
After you’re finished
- Let the seam cool down before moving or adding any pressure
- Clear extrusion welder out and leave it as clean as you can for next time
