Welding environment is one of the most important factors that restrict 13CrMo4-5 welded steel pipe quality.
The welding environment requires proper temperature, humidity and wind speed to ensure good appearance and internal quality of the 13CrMo4-5 welded steel pipe weld microstructure.
Therefore, the welding environment shall comply with the following requirements:
1. The ambient temperature of the welding shall be sufficient to ensure the necessary temperature for the welding of the 13CrMo4-5 welded steel pipe welding parts and to protect the welder's skills.
When the ambient temperature is lower than the minimum allowable temperature of the 13CrMo4-5 welded steel pipe welding material, the preheating requirements shall be put forward according to the welding process evaluation.
2. The wind speed during welding shall not exceed the corresponding specified value of the selected 13CrMo4-5 welded steel pipe welding method.
When exceeding the specified value, there should be wind protection facilities.
3. The relative humidity within 1m of welding arc shall not be greater than 90% (no more than 80% when aluminum and aluminum alloy are welded).
4. The welding work shall not be carried out when the surface of the 13CrMo4-5 welded steel pipe welding parts is wet, or the welder and 13CrMo4-5 welded steel pipe welding parts fail to meet the requirements without protective measures or measures taken during rain or wind.
