预钎焊准备工作对铜门制造商的焊接质量大有帮助我们现代钎焊艺术是准备材料，而不是发现钎焊时遗漏了什么。

Pre brazing preparation work is of great help to the welding quality of copper door manufacturers. Our modern brazing art is about preparing materials, not discovering what was missed during brazing.

其次，焊接工作完成：

Secondly, the welding work is completed:

为避免变形和其他操作，移动到焊缝末端的另一点时需要更加小心，切不可松动。

To avoid deformation and other operations, be more careful when moving to another point at the end of the weld seam and do not loosen it.

、焊后检查工作：

Finally, post weld inspection work:

为了达到焊接的质量和效率，需要在焊接冷却后及时检查济南铜门的外观。同时，如果出现裂缝，也要果断、正确地处理。的方式。如有需要，我们可以聘请更的设计人员。老师前来指导。

In order to achieve the quality and efficiency of welding, it is necessary to promptly inspect the appearance of Jinan copper doors after welding cooling. At the same time, if cracks appear, they should be dealt with decisively and correctly. The way. If necessary, we can hire more professional designers. The teacher came to provide guidance.

焊接工艺多的铜门企业非常关注，因为只有的焊接大师和更好的焊接设备才能在的标准下准确焊接，才能保证焊接点的准确性。焊接，焊接技术过硬.效果的优势体现出这些是保证铜门质量的关键。

Copper door enterprises with multiple welding processes are very concerned because only professional welding masters and better welding equipment can accurately weld under professional standards and ensure the accuracy of welding points. Welding, with excellent welding techniques and superior results, is the key to ensuring the quality of copper doors.

山东铜门的上色方法有哪些?

What are the coloring methods for Shandong bronze doors?

1、铜门的去除、脱脂、氧化、除垢、水洗、酸洗、抛光、水洗、中和、水洗、着色处理、水洗、烘干等后处理工艺。

1. The post-treatment processes for copper doors include removal, degreasing, oxidation, descaling, water washing, acid washing, polishing, water washing, neutralization, water washing, coloring treatment, water washing, and drying.

2、酸洗抛光建议使用铜酸洗抛光液进行去除，目的是使黄铜型材发光。

2. It is recommended to use copper pickling and polishing solution for removal during pickling and polishing, in order to make the brass profile glow.

3、着色产品是一种工作液，将工件浸泡在该产品中，黄铜表面会在大约2分钟内变黑和变蓝。根据实验结果，浸渍时间为20-25分钟时，一般的变色质量较好，可以获得较好的铜艺术品氧化性能，工件可反复浸渍，增加变色层的厚度，达到满意的效果。

3. Coloring product is a working fluid that immerses the workpiece in, causing the brass surface to turn black and blue within approximately 2 minutes. According to the experimental results, when the immersion time is 20-25 minutes, the color changing quality is generally good, and good oxidation performance of copper artwork can be obtained. The workpiece can be repeatedly immersed to increase the thickness of the color changing layer and achieve satisfactory results.

4、如果想要达到古铜色，经过以上步骤后，可以用砂纸打磨，达到想要的效果。

4. If you want to achieve a bronze color, after the above steps, you can use sandpaper to polish it to achieve the desired effect.
