What should a welder do if they notice a defect while welding?

When a welder notices a defect while welding, the most appropriate action is to stop the welding process and assess the defect. This approach allows the welder to evaluate the severity and implications of the defect on the quality and integrity of the weld. By halting the work, the welder can prevent further damage, ensure safety, and maintain high standards of craftsmanship.

Assessing the defect can involve examining the nature of the issue—whether it’s a porosity, crack, insufficient joint penetration, or another form of imperfection—before deciding on the appropriate corrective measures, which may include repairing the defect or reworking the entire weld area. This proactive approach not only aids in compliance with welding standards but also enhances overall weld quality and safety in the final product. Ignoring the defect or attempting to cover it up could lead to compromised structural integrity, which is not acceptable in any welding practice. Additionally, timely reporting to supervisors could be necessary if specific protocols or assistance is needed for a comprehensive evaluation or repair.
