3.2.5. Heat Treatment 热处理
The preheat temperature Tp shall be calculated with the following formula:
预热温度Tp应当按照如下公式计算：
Tp= 750 x CET - 150 °C
with:
其中：
The actual temperatures must be monitored by suitable test methods.
实际温度必须以合适的测试方法来监控。
Forced cooling of the welding points is not permissible. When welding work is performed in the open air, the welding points must be appropriately covered as a protection against unfavorable weather conditions.
不允许对焊点施行强迫冷却。如果是在户外执行焊接工作，则必须对焊点加以适当遮蔽，以预防不利天气状况的影响。
During the welding and cooling of the weld (blue heat), violent movement and/or vibration of the welded parts must be avoided.
在焊接和焊接冷却（蓝热）期间，必须避免焊接零部件的剧烈移动和/或振动。
If stress relieving heat treatment is required, it shall preferably be performed directly from the welding heat. The following parameters must be observed:
如果需要进行应力解除热处理，则最好直接以焊热来处理。以下参数必须遵守：
- heating rate not faster than 50 °C per hour,
－加热速率不超过50°C/小时；
- holding time one hour per 25 mm plate thickness plus safety margin of two hours,
－板材厚度每25 mm的热保持时间为1小时，加上2小时的安全裕度；
- cooling rate in the furnace not faster than 50 °C per hour.
－炉中冷却速率不超过50°C/小时。
3.2.6. Weld Dressing 清理焊缝
Weld spatter and slag must be removed after the weld zone has cooled. Any further cleaning of the weld zone shall be in accordance with the requirements for surface treatment as protection against corrosion.
在焊接区域冷却后，必须清除焊接飞溅和焊渣。对焊接区域的进一步清理，应当遵照对表面处理的要求，以防止腐蚀。
If this is necessary for the assembly of the components or specified in the respective drawings, the welds have to be appropriately finished.
如果对于部件总成而言有必要，或是在相应的图纸中有所规定，则需要对焊缝进行修饰。
Any aids or temporary attachments welded to the component must be removed without causing damage to the base metal. It is not permissible to struck off such aids or attachments. The area in question must be carefully ground.
对部件进行的任何辅助焊接或临时性连接焊接都必须去除，而不得损伤基底金属。不得将这类辅助件或连接件敲除。所涉区域必须小心接地。
