钢结构件的生产加工主要是焊接作业，因此焊条也应选择合格的正规厂家焊条，并必须有材料陈述。焊条在使用前应在干燥箱内干燥。埋弧焊选用的焊丝和焊剂必须与使用的母材相匹配。
The production and processing of steel structural members mainly involves welding operations, so welding rods should also be selected from qualified and regular manufacturers, and must have a material statement. Welding rods should be dried in a drying oven before use. The welding wire and flux selected for submerged arc welding must match the base metal used.

三、持证上岗
3、 Work with certificate
钢结构生产加工焊接作业属于特殊作业，操作人员必须经过技术培训和安全培训，取得相关证书，才能持证上岗，否则不能进行焊接。此外，天车还将用于钢结构制造，天车的操作也属于特殊操作，还需取得相关证书。
The production, processing, and welding operations of steel structures are special operations. Operators must undergo technical and safety training and obtain relevant certificates before they can work with certificates. Otherwise, welding cannot be performed. In addition, the crown block will also be used for the manufacture of steel structures. The operation of the crown block is also a special operation, and relevant certificates are required.
四、焊接工艺
4、 Welding process
钢结构的焊接顺序应制定合理的焊接工艺。当焊接几种焊缝时，应先焊接收缩变形较大的焊缝，然后焊接纵向焊缝，这是焊接过程中钢结构构件的技能。钢结构的生产加工，注重精度，从下料到焊接必须严格要求，严格操作。在整个生产过程中，不能出现非法操作的现象，做到安全在心，质量在心。
The welding sequence of steel structures should be based on a reasonable welding process. When welding several types of welds, it is necessary to first weld the welds with large shrinkage deformation, and then weld the longitudinal welds. This is a skill for steel structural members during the welding process. In the production and processing of steel structures, attention should be paid to accuracy. From blanking to welding, strict requirements and strict operations must be implemented. During the entire production process, there should be no illegal operations, and safety and quality should be at the heart.
