All,
Below is the Work Instruction for the Hilti stamp gun. Satit and I Roughed this WI out last week. Any questions or comments Please add suggestions in a different text color. We need to get this equipment into production as soon as possible upon Dons approval of this WI.
It is very important that all operators and supervisors know that the primer strips can cause serious injury if used improperly or incorrectly. No horseplay will be tolerated in regards to the use of this equipment. Our Safety team needs to keep a close watch on the stamp strip handling and usage of the equipment.
1. Strict control of primer strips and Hilti gun shall be maintained at all times. Foremen will sign out primer strips for their area on a daily basis. All unused & used strips shall be turned into store and accounted for at the end of every shift.
2. At the end of the shift the gun and all strips will be turned back into store.
3. The gun and unused strips will be kept in the locked cabinet when not in use. Store operator and plant secretary will have the only keys to the cabinet.
4. Before stamping begins make sure the operator has been properly trained. Notify Safety Officer when using equipment.
5. Position pieces to be stamped so that there is proper backing. This is extremely important on angle and smaller pieces. Without proper support the stamp will not be deep enough into material.
6. Write piece mark on piece near the stamp area so the piece mark can be easily verified after stamping. At each step look at loaded stamp to verify it is correct BEFORE stamping. After stamping verify that each stamp mark is correct. Verify that stamp is deep enough into material so that it does not get blasted off at blast machine.
7. J 1437 will require 2 shots per piece mark. Some parts may require a third shot or stamping to be done manually. Verify that each stamp mark is correct. Verify that stamp is deep enough into material so that it does not get blasted off at blast machine.
8. The first shot should typically cover all parts on skid. The gun should be loaded with this stamp and all shots should be made without changing stamp. Verify that each stamp mark is correct. Verify that stamp is deep enough into material so that it does not get blasted off at blast machine.
9. The second shot will vary per piece. Stamp will have to be changed for each individual piece. Verify that each stamp mark is correct. Verify that stamp is deep enough into material so that it does not get blasted off at blast machine.
10. If a third shot is required the Engineer and Supervisor will determine the most time efficient manner to apply the stamp. Some cases it may be more efficient to stamp manually.
