For heavy attachments and structural components, welding quality affects safety, dimensional stability, and service life. Before welding, plates and grooves should be clean and fit-up gaps checked against the process plan.
Parameters must match plate thickness, material, joint design, and position. Preheat and interpass-temperature controls may be required by the approved procedure. Fixtures, sequence, and balanced welding help manage distortion.
After welding, visual and dimensional checks are followed by the specified inspection method for critical seams. Records should identify nonconformities and rework. Surface appearance alone is not a substitute for controlled preparation, process execution, and verification.
