1. Post-straightening low-temperature stress-relief tempering If a tempering process involving holding at 300°C for 30 minutes is performed after

Step 1: Re-verification of Core Accuracy (Baseline Validation) Re-test all key indicators against factory accuracy standards to confirm that the corre

Step 1: Observe visual indicators to quickly rule out cases where correction is unnecessary. Correction is likely not required if the following issues

I. Precision Rebound and Deformation This is the most common issue, typically caused by a failure to fully eliminate new stresses after the straighten

I. Flame Straightening (Most common method; suitable for various types of deformation; offers stable results) Flame straightening is cost-effective an

Core Quantitative Criteria (Definitive Basis) Moderate deformation is determined if both of the following conditions are met: 1. Planar warping/distor

Step 1: Direct determination using quantitative metrics (primary criteria) Severe deformation is confirmed if any of the following conditions are met:

Step 1: Establish Acceptance Criteria Retrieve the welding table's factory precision specifications to serve as the benchmark. Standard acceptance

1. Minor deformation (deformation ≤ 0.03mm/1000mm): Cold straightening method This type of deformation involves minimal dimensional deviation and c

Step 1: Prepare the Inspection Reference Place the welding table on a standard inspection platform. Adjust the support pads to level the table roughly

I. Mechanical Straightening: Suitable for mild to moderate planar warping and bending deformation. This method counteracts deformation by applying ext
