7 Tips for Welding Abrasion-Resistant Plate Modern How to weld and repair saph400 carbon plate

When welding abrasion-resistant (AR) plate to a piece of equipment, it is important to select the most appropriate filler metal for the applicationwhether its a matter of repair or the fabrication of a new plate onto a structure. AR plates have an incredibly high hardness and are designed to provide long service life in harsh conditions.9 Rules for Successful Weld Repair of High Strength Steel How to weld and repair saph400 carbon plateThis limits the heat input into the metal which allows the steel to achieve its full strength after welding. A. weaving technique could cause reduced weld strength as well as re-cracking after the weld cools. Clean the area of any grease, dirt, paint, oil, rust, or other foreign material at least 2 inches (50 mm) on either side of the repair.AR400 Steel Welding on a Backhoe BucketA wear plate is usually a quenched and tempered steel and is generally a lot more crack sensitive due its chemical composition of carbon, chromium, etc. The base metal around the weld rapidly heats and cools during welding, resulting in a heat affected zone (HAZ) with high hardness compared to surrounding areas unaffected by heat.
