8 Key Precautions for Welding Rectangular Square Pipe

Welding rectangular square pipe requires attention to detail and strict adherence to safety protocols. Here are eight essential precautions to ensure a safe and efficient welding process:

1. Check Gas Leakage Before Ignition

Before lighting the welding torch, inspect all gas valves and connections for leaks. If any leakage is detected, repair it immediately to prevent hazardous situations when welding rectangular square pipe.

2. Keep Gas Channels Free of Oil Contamination

Ensure that all gas passages in the welding equipment are free from oil or grease. Oxygen reacting with oil can cause explosions, posing serious risks during rectangular square pipe welding.

3. Handle Backfire Properly

If a backfire occurs, immediately shut off the acetylene valve (for powder spray guns) or the main valve (for wire spray guns). Wait briefly before reopening the valve to clear residual smoke. Always use a spark lighter for ignition—never use a cigarette to avoid burns.

4. Store the Torch Correctly

When not in use, hang the torch along with its hose or store it in a protective case to prevent dust and debris from clogging the nozzle.

5. Verify Suction Performance Before Use

Before welding rectangular square pipe, check the torch’s suction performance. Connect the oxygen hose, open the acetylene and oxygen valves, and place a finger over the acetylene inlet. If suction is felt, the torch is functioning properly. Otherwise, inspect and repair it.

6. Never Block the Nozzle While Valves Are Open

Avoid covering the torch nozzle with hands or objects when both oxygen and acetylene valves are open. This prevents oxygen backflow into the acetylene generator, which can be dangerous.

7. Avoid Placing a Lit Torch on Surfaces

Never lay a burning torch on the ground or any object, as this can lead to accidents. Also, ensure the nozzle remains undamaged to prevent backfires or explosions.

8. Maintain Lubrication in Moving Parts

Regularly lubricate transmission components with a thin layer of molybdenum disulfide grease to ensure smooth operation during rectangular square pipe welding.

By following these precautions, welders can enhance safety and efficiency when working with rectangular square pipe. Proper handling and maintenance of equipment are crucial for achieving high-quality welds while minimizing risks.
