What's wrong with argon arc welding in rainy days?

1. Humidity influence: rainy weather, high humidity, water molecules in the air will affect the quality of argon and welding wire, leading to argon deterioration and oxide formation on the surface of welding wire, thus affecting the welding effect.

2. Temperature influence: low temperature and dense cold air in rainy weather will lead to untimely cooling of welding torch, and cracks and bubbles will easily occur in welding.

3. Spark instability: electrostatic field strength in rainy weather is easy to cause spark interference, which makes argon arc welding spark unstable and welding defects increase.

4. Humidity affects the arc: rainy and humid weather is easy to make the arc jump and the weld quality is low.
