Copper door is a tailor-made product. Its price is usually determined by the size of the door leaf, the thickness of the door panel, the complexity of carved decoration and the grade of the lock.

（1）根据现场实际尺寸，用方钢焊接框架，接口处采用满焊处理，外扣铜板型材焊接而成。

(1) According to the actual size on site, the frame is welded with square steel, the interface is fully welded, and the external buckle copper plate profile is welded.

（2）铜板的制作方法为：剪裁→折弯→人工拉丝→化学氧化→清洗→自然晾干→喷涂保护层（专用清漆）→高温烘箱烘烤（160℃-220℃）。

(2) The manufacturing method of copper plate is: cutting → bending → manual wire drawing → chemical oxidation → cleaning → natural drying → spraying protective layer (special varnish) → high temperature oven baking (160 ℃ - 220 ℃).

（3）铜门框架的制作方法为：选材→切割→焊接→打磨→防腐防锈处理→切边戳磨→铜焊粘贴及覆盖。

(3) The manufacturing method of copper door frame is as follows: material selection → cutting → welding → grinding → anti-corrosion and anti rust treatment → cutting edge stamping and grinding → brazing, pasting and covering.

（4）安装玻璃时玻璃与铜板接口处采用玻璃胶密封处理，玻璃与方钢接口处用专用防撞条垫底。

(4) When installing glass, the interface between glass and copper plate shall be sealed with glass glue, and the interface between glass and square steel shall be padded with special anti-collision strip.

（5）门扇的安装：根据门框的位置，在地面上找出相应的位置固定地弹簧，然后安装铜门扇。

(5) Installation of door leaf: according to the position of door frame, find out the corresponding position on the ground, fix the ground spring, and then install the copper door leaf.

（6）安装铜门标准：铜门与铜门、门框之间的缝隙小于与等于8mm，铜门与铜门之间平整度不大于2mm。

(6) Standard for installing copper door: the gap between copper door and copper door and door frame shall be less than or equal to 8mm, and the flatness between copper door and copper door shall not be greater than 2mm.

焊接工艺

welding technology 

1、焊接质量的好坏直接影响装配质量，因此在构件安装时，要严格控制焊接处的间隙，错边等误差，经安装装配后的焊接节点须经专人检查合格后才能交焊工施焊。

1. The welding quality directly affects the assembly quality. Therefore, during component installation, it is necessary to strictly control the welding gap, misalignment and other errors. The welded nodes after installation and assembly must be inspected by a specially assigned person before they can be handed over to the welder for welding.

2、焊接前的准备工作

2. Preparation before welding

（1）装配好的焊接节点专人检查后交于焊工施焊；

(1) The assembled welding nodes shall be inspected by a specially assigned person and handed over to the welder for welding;

（2）检查焊接位置的脚手搭设是否安 全可靠；

(2) Check whether the scaffold erection at the welding position is safe and reliable;

（3）清理焊接坡口区，将经烘焙的焊条用保温筒带现场焊接地点。

(3) Clean the welding groove area and bring the baked electrode to the site welding site with insulating cylinder.

3、焊接工作

3. Welding work

（1）为避免焊接变形，焊接时采用对称焊接（包含对焊、立焊、斜焊）；

(1) In order to avoid welding deformation, symmetrical welding (including butt welding, vertical welding and oblique welding) shall be adopted during welding;

（2）焊接过程中逐道焊缝清渣，除飞溅物，发现缺陷及时用角向砂轮打磨，除去缺陷；

(2) During the welding process, slag shall be removed one by one to remove spatters. If defects are found, they shall be polished with angular grinding wheel in time to remove defects;

（3）焊接工作结束，将焊缝区及焊接工作位置场地清理干净，转移到下一焊接节点。

(3) After welding, the weld area and welding site shall be cleaned and transferred to the next welding node.

4、焊后检查

4. Post weld inspection

（1）待焊缝冷却后，进行焊缝外观检查；

(1) After the weld is cooled, the weld appearance shall be inspected;

（2）焊缝中不得有裂缝，焊缝金属与母材间完全熔合，所有破口均被填满；

(2) There shall be no cracks in the weld, the weld metal shall be fully fused with the base metal, and all cracks shall be filled;
