Procedure
For best results, clean area of all matter and debris. Make sure the joint area is dry, as moisture will have a tendency to cause porosity. In overlaying iron base metals, apply the first layer at the lowest amperage possible and weave to keep the base metal dilution to a minimum. Apply three passes where possible, keeping in mind that all slag must be thoroughly removed between beads. A 300ยบ F preheat and interpass temperature is recommended.
