Practice pies are designed to get you comfortable welding thin wall tubing without having to burn through more expensive or exotic metals just for the sake of practice. 

Available in mild steel andaAluminum, each practice pie kit consists of 5 pie cuts with an 18 degree transition angle (9 degrees per side of the pie). All pie cuts are laser cut from 16 gauge (0.065") tubing with a 3" outside diameter. Each pie is laser etched every 90 degrees to help you with orientation and lineup!

Each kit includes 5 pie cuts to total 90 degrees.

You need 4 kits to weld a pie cut donut.
