Weld Coupon Cutting and Bevelling Machine — Tri Tool CouponMaster
The Tri Tool CouponMaster is a bench-mounted weld coupon preparation machine based on the 208B BEVELMASTER. It faces, bevels and counterbores pipe coupons for welding schools, training centres and qualification programs. Air and electric packages are available through Justram; confirm the supplied configuration and electrical approval documentation.
Prepare and reclaim pipe weld coupons
The CouponMaster combines a 208B ID-mounted beveling machine with a bench stand. Adjustable tool holders support repeatable weld-end preparation once the mandrel, cutting bits and pipe dimensions are matched to the job.
When preparing coupons from long pipe or reclaiming welded practice pieces, use a suitable separate cutting method to remove the required section before re-preparing the ends. Coupon reuse depends on the remaining length, material condition and training or test requirements. Have the instructor or examiner establish the permitted preparation; there is no universal number of reclamation cycles or heat-affected-zone removal allowance.
