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
