Prepare welding procedure specification (WPS)
Develop a welding procedure specification (WPS) that outlines the specific steps and requirements for the welding process. Include information such as the welding process, the materials to be welded, the welding parameters, and any special considerations or standards that need to be followed. This document serves as a guide for the welding process and ensures consistency and quality throughout.
Set up welding equipment based on WPS
Configure the welding equipment based on the welding procedure specification (WPS). Ensure that all the required parameters, such as voltage, current, wire feed speed, and gas flow rate, are set correctly. This step is crucial for achieving consistent and quality welds.
Conduct a pre-welding inspection
Perform a thorough inspection of the welding setup and the materials before starting the welding process. Check for any potential issues, such as improper fit-up, contamination, or defects in the materials. This step helps identify and address any issues that could affect the quality of the welds.
Commence the Welding task
Start the welding process based on the established welding procedure specification (WPS). Follow the recommended techniques and parameters to ensure consistent and quality welds. Monitor the welding parameters throughout the process to maintain control and make adjustments if necessary.
Perform intermediate inspections during welding
Carry out intermittent inspections during the welding process to assess the quality of the welds. Inspect for defects, such as porosity, lack of fusion, or excessive spatter. Identify any issues and take corrective actions to maintain the desired quality.

5
Assess joint alignment
Complete final welding inspection
Perform a comprehensive inspection of the final weldments to ensure they meet the required quality standards. Check for any defects, discontinuities, or deviations from the desired specifications. This step ensures that the welding process has been successfully executed and the weldments are fit for their intended purpose.
Compare final weldment to the initial design and specifications
Compare the final weldments to the initial design and specifications to ensure they meet the required dimensions, tolerances, and quality criteria. Identify any discrepancies or deviations and take corrective actions if necessary. This step ensures that the final weldments align with the intended design and functionality.
Evaluation of the weld quality
Assess the quality of the welds based on visual inspection, mechanical testing, or non-destructive testing methods. Determine if the welds meet the required standards for strength, integrity, and appearance. This evaluation helps verify the success of the welding process and ensures the welds are suitable for their intended use.

Verification of the welder's qualifications
Confirm that the welder performing the welding tasks possesses the necessary qualifications and certifications. Verify their skills, knowledge, and experience in the specific welding process and materials being used. This step ensures that the welder is competent and capable of producing quality welds.
Submit welding documentation for review
Compile and submit the necessary welding documentation, including the welding procedure specification (WPS), inspection reports, and any other relevant records, for review and approval. This step ensures that the welding activities have been properly documented and verified for quality compliance.

Compile report detailing welding process and results
Prepare a comprehensive report that documents the welding process, including the procedures followed, equipment used, inspection results, and any corrective actions taken. Include the welder's qualifications and certifications as well. This report serves as a record of the quality control activities and provides valuable information for future reference.
Discuss any nonconformities or anomalies
Hold a discussion or meeting to address any nonconformities or anomalies identified during the welding process or the quality control inspections. Analyze the root causes, determine appropriate corrective actions, and assign responsibilities for implementation. This step ensures that any issues are appropriately addressed and prevented in the future.
Implementation of corrective action for any identified faults
Take the necessary steps to implement corrective actions for any identified faults or nonconformities. Assign responsibilities, provide clear instructions, and monitor progress to ensure the prompt and effective resolution of the issues. This step helps prevent potential defects and ensures continuous improvement in the welding process.
Re-inspection post-correction, if necessary
Conduct a follow-up inspection after implementing corrective actions to verify the effectiveness and success of the measures taken. Check if the identified faults have been resolved, and confirm that the weldments now meet the required quality standards. This step ensures that the corrective actions were successful and that the welding process is back on track.
