Example of QUALITY CONTROL -
Seen below are test pieces of the Chine Welding of a Huffler 40

Records are kept of the weld preparation and welding process in order to replicate
the weld on the job itself

The test pieces are then cut into 10mm wide strips, then sanded across the exposed weld
and checked for imperfections. They are then 'bent back' on themselves across the welds.
