Claims
- 1. An arc welding process comprising the steps of:
- preparing a welding material and
- deposition a molten bead of said welding material on a workpiece, wherein said welding material consists essentially of:
- 0.03% by weight or less of carbon; 1.00% by weight or less of silicon; 1.00% by weight or less of manganese; from 16.0 to 21.0% by weight of chromium; from 0.30 to 0.80% by weight of niobium; from 0.30 to 0.80% by weight of copper; 0.025% by weight or less of nitrogen; and the balance of iron, and wherein the structure of the welding material is ferrite.
- 2. An arc welding process according to claim 1, wherein the carbon content of said welding material is in a range of from 0.01 to 0.03% by weight; the silicon content is in a range of from 0.50 to 1.00% by weight; and the manganese content is in a range from 0.40 to 1.00% by weight.
- 3. An arc welding process according to claim 1, wherein the step of preparing said welding material comprises forming the welding material into a rod.
- 4. An arc welding process according to claim 1, wherein the step of preparing said welding material comprises forming the welding material into a wire.
- 5. An arc welding process comprising the steps of:
- preparing a welding material and
- depositing a molten bead of said welding material on a workpiece, wherein said welding material consists essentially of:
- 0.03% by weight or less of carbon; 1.00% by weight or less of silicon; 1.00% by weight or less of manganese; form 16.0 to 21.0% by weight of chromium; 5.0% by weight or less of nickel; from 0.30 to 0.80% by weight of niobium; from 0.30 to 0.80% by weight of copper; 0.025% by weight or less of nitrogen; and the balance of iron, and wherein the structure of the welding material is ferrite.
- 6. An arc welding process according to claim 5, wherein the carbon content of said welding material is in a range of from 0.01 to 0.03% by weight; the silicon content is in a range of from 0.50 to 1.00% by weight; and the manganese content is in a range from 0.40 to 1.00% by weight.
- 7. An arc welding process according to claim 5, wherein the step of preparing said welding material comprises forming the welding material into a rod.
- 8. An arc welding process according to claim 5, wherein the step of preparing said welding material comprises forming the welding material into a wire.
