Choosing a Welding Procedure


Pendulum Welding (PW)	Speed Welding (SW) A.K.A. Draw Welding	Extrusion Welding (EW)

Slowest welding technique	Faster than PW	Faster than SW

Best for very confined spaces	Allows welding in tight spaces	More space needed due to tool size

Best for short seams and repair work	Not suitable for PVC-U welding	Better seam quality

For plastic as thick as 5-10 mm	For plastic as thick as 10 mm	For plastic as thick as 40 mm

The welder must ensure the following: even heating of both plastic and welding rod vertical orientation of welding rod sufficient welding force	Advantages over pendulum welding: higher welding speed thicker materials with larger gaps can be welded
