Welding Parameters
The supplied product data gives the following operating range. These values should be treated as reference parameters and adjusted only in accordance with the approved welding procedure and manufacturer's instructions.
Parameter | Supplied Value |
|---|---|
Welding Process | Gas-Shielded Flux Cored Arc Welding (FCAW-G) |
Shielding Gas | CO₂ |
Current Range | 130–230 A |
Voltage Range | 26–31 V |
Polarity | DCEP (DC Electrode Positive) |
Maximum Interpass Temperature | 100°C |
Welding Speed | 300–400 mm/min |
Before production welding, confirm the wire diameter, joint design, material thickness, welding position and gas flow requirements against the applicable technical data sheet. The table does not replace a qualified welding procedure specification (WPS).
Deposited Metal Chemical Composition
The following values are transcribed from the supplied inspection report.
Element | Requirement (%) | Actual Result (%) |
|---|---|---|
Carbon (C) | ≤0.04 | 0.026 |
Manganese (Mn) | 0.5–2.5 | 1.120 |
Silicon (Si) | ≤1.0 | 0.61 |
Sulfur (S) | ≤0.03 | 0.005 |
Phosphorus (P) | ≤0.04 | 0.013 |
Chromium (Cr) | 18.0–21.0 | 19.960 |
Nickel (Ni) | 9.0–11.0 | 9.66 |
Molybdenum (Mo) | ≤0.5 | 0.02 |
Copper (Cu) | ≤0.5 | 0.01 |
The reported composition indicates a low-carbon chromium-nickel weld-metal chemistry within the limits listed in the supplied report. Actual results may vary by production batch and testing method. Confirm the product classification and applicable standard edition against the official certificate before presenting these limits as classification-wide requirements.
Deposited Metal Mechanical Properties
Property | Requirement | Actual Result |
|---|---|---|
Yield Strength | Not specified in supplied table | 471 MPa |
Tensile Strength | ≥520 MPa | 611 MPa |
Elongation | ≥35% | 42% |
Bend Test | As specified | Pass |
Radiographic Test | Grade II requirement shown | Grade I result shown |
The supplied test results show tensile strength and elongation above the stated minimum requirements. The bend test is recorded as passing, and the radiographic result is listed as Grade I against a Grade II requirement in the report. Acceptance criteria depend on the governing standard and inspection procedure, so the original certificate should be retained for technical review and contractual verification.
