BASIC FLUX COATED LOW HYDROGEN ELECTRODE DEPOSITING TOUGH AND WORK-HARDENING WELD METAL FOR WORK INVOLVING EITHER HIGH TEMPERATURE ABRASION OR IMPACT ABRASION PROPERTIES
HMC-16
PRODUCT DESCRIPTION
The design of the electrode is synthetic, i.e.: a mild steel core wire with the alloying elements contained in the flux. The weld deposit is austenitic and metal recovery is some 135% with respect to weight of the core wire. A blend of silicates is used to bind the flux that ensures both coating strength and resistance to moisture absorption.
WELDING FEATURES OF THE ELECTRODE
The electrode is stable on both AC and DC. Initial arc strike is easy, as is restriking. The weld seams are smooth, bright and convex in shape. Slag is
readily detachable. To prevent micro solidification cracking, interpass temperature should be kept to a minimum and this may be achieved by interpass cooling.
APPLICATIONS AND MATERIALS TO BE WELDED
The electrode may be used with both a single and multi-layer technique overlay on mild steel or 13%Mn steel to give an austenitic work hardening deposit that has improved corrosion resistance over conventional alloys. This electrode recommended for rail point and crossing, pipe subjected to high temperature and high pressure, hard surfacing of hot shear, forging moulds, or hot forging dies.
WELDING AMPERAGE AC and DC
OTHER DATA
Electrodes that have become damp should be re-dried at 150ºC for 1 hour.
