Welding Codes that allow the use of Crushed Slag (recycled flux) as a welding consumable:
American Welding Society (AWS)
American Society of Mechanical Engineers (ASME)
Canadian Standards Association (CSA)
The above codes all state that "Each Lot / Batch Shipped" must be tested.

To determine whether code compliance is required for your operation call 1-800-377-3103 USA & Canada.

All product testing is done by a third-party testing facility.

Your company receives the original test documents for your records for each lot you have crushed.

Third-party testing assures that your crushed flux meets the specifications you require.

We will provide examples of test results, as well as answers to any questions you may have.
