How to Pre-tighten a 3D Welding Table?

Preparation Before Pre-tightening

1. Environment and Tools: Find a flat, firm, vibration-free surface. Prepare a level (electronic or bubble level), wrench, and washers.

2. Platform Inspection: Clean the work surface and check the outriggers and support bolts for damage. Ensure the platform can be adjusted freely.

Pre-tightening Operation Steps

1. Initial Leveling: Place the platform and adjust the outriggers to make it roughly level.

2. Precise Adjustment: Use a level to measure the platform horizontally and vertically. Lower the corresponding outrigger if any part is too high, until the bubble is centered.

3. Cross-Verification: Adjust along the diagonals to ensure the platform is level and not twisted.

Precautions

1. Safety First: Avoid slipping during adjustment to prevent the platform from tipping over.

2. Gradual Adjustment: Make small adjustments each time, avoiding large adjustments at once to prevent introducing new errors.

3. Regular Checks: Even after leveling, regular checks are necessary, as changes may occur over time.

Why is Pre-tightening Necessary?

1. Ensuring Accuracy: A level platform is fundamental to welding accuracy and reduces weld defects.

2. Improving Stability: Reduces vibration, making welding more stable.

3. Extending Lifespan: Prevents excessive localized stress and protects the platform structure.
