NOTE
When fillet welding our 4/5 thickness plate to a job, Stainless steel consumables should be used otherwise a brittle weld may occur (SEE AOA TECHNICAL INFORMATION SHEET). A brittle weld will occur if a mild steel electrode comes into contact with the hardface layer as carbon and chromium will be picked up from the hard surfacing.
