A heavy coated low hydrogen, iron powder type electrode ideally suited for producing tough and ductile welds of radiographic quality in boilers, pressure vessels and heavy structures subjected to dynamic loading. The electrodes have a metal recovery of about 115%. Some typical applications include heavy structures subjected to dynamic loading and impact, highly restrained joints, coaches, wagons, penstocks, boilers, pressure vessels, earthmoving machines, etc.
1. Ensure the electrodes are dry. Re-dry the electrodes at 250-300 C for one hour.
