SUREWELD 7024
Sureweld 7024 is an iron powder electrode that produces high deposition rates on horizontal and downhand welding. It offers excellent operator appeal, excellent bead appearance and selfcleaning slag. It is ideal for high speed horizontal fillet and lap welds on mild and some alloy steels, such as those found on constuction equipment, truck bodies, ships, barges and railcars.
Features
Sureweld 7024 is a high speed, heavy-coated, iron powder electrode for high deposition rates on horizontal and downhand welding. Excellent operator appeal, produces equal 45º fillets, thereby eliminating over welding. Excellent bead appearance and self-cleaning slag. This electrode has good weldability and superior mechanical properties. It is particularly useful in obtaining increased penetration with little or no root porosity in horizontal or positioned fillets. Sureweld 7024 is ideal for making high speed horizontal fillet and lap welds on mild and some alloy steels, such as earthmoving and construction equipment, truck bodies, ships, barges and railcars. Sureweld 7024 exceeds the AWS A5.1 elongation % and Charpy v-notch requirements for 7024-1.

Extra Info
Procedure
- Drag technique should be used on horizontal and flat fillets. Tilt electrodes 5° to 10° in direction of travel and 40° to 50° from base plate in horizontal fillet. No weaving is necessary.
