钢结构的焊接，我们在实施过程中，应事先了解哪些具体内容，这样操作起来才不至于出错，这也是焊接人员，在对无锡钢结构进行焊接时，非常关心的。因此为了更好普及这些知识：

In the process of welding steel structures, we should first understand the specific content so that we can operate correctly. This is also a concern for welding personnel when welding Wuxi steel structures. Therefore, in order to better popularize this knowledge:

1.作业条件

1. Homework conditions

(1)要对图纸很熟悉，并做好焊接技术交底工作。

(1) Be familiar with the drawings and do a good job in welding technology disclosure.

(2)在施焊前，应检查焊工的上岗证是否在有效期限内，是否能担当焊接工作。

(2) Before welding, it is necessary to check whether the welder's work permit is valid and whether they are capable of performing welding work.

(3)现场供电条件，应符合焊接用电要求。

(3) The on-site power supply conditions should meet the requirements for welding electricity.

(4)如果施工温度低于零摄氏度，那么应先进行预热，然后再进行操作。

(4) If the construction temperature is below zero degrees Celsius, preheating should be carried out first before operation.

2.冬期低温焊接

2. Winter low-temperature welding

(1)采用电弧焊时，如果环境温度低于零摄氏度，那么应对焊接工艺参数进行适当的调整，并遵守常规的焊接规定。此外，焊缝和热影响区的冷却，应缓慢进行。

(1) When using arc welding, if the ambient temperature is below zero degrees Celsius, the welding process parameters should be adjusted appropriately and conventional welding regulations should be followed. In addition, the cooling of welds and heat affected zones should be carried out slowly.

(2)如果风力超过规定，那么应采取挡风措施。

(2) If the wind exceeds the prescribed limit, windproof measures should be taken.

(3)焊接后未冷却的接头，应避免与冰雪相接触。

(3) The joints that have not been cooled after welding should avoid contact with ice and snow.

(4)为了防止产生焊接裂纹，对钢结构焊接时应进行预热，并控制好层间温度。

(4) In order to prevent welding cracks, preheating should be carried out during steel structure welding, and the interlayer temperature should be controlled well.

3.质量标准

3. Quality standards

(1)钢结构焊接工程的检验的划分，分分为若干个批次，分批进行检验。

(1) The inspection of steel structure welding engineering is divided into several batches and conducted in batches.

(2)对于碳素结构钢，在焊接完成后24小时内，要进行焊缝探伤检验。

(2) For carbon structural steel, weld seam inspection must be conducted within 24 hours after welding is completed.

4.应注意的质量问题

4. Quality issues to be noted

(1)焊接部位的相对尺寸和位置，应严格进行控制，准确无误后才能进行焊接，焊接时也要精心认真准确进行操作。

(1) The relative size and position of the welding area should be strictly controlled, and welding can only be carried out after accuracy is ensured. During welding, careful and accurate operation should also be carried out.

(2)焊接过程中，不能突然中断，不能使用大的电流，以防产生焊接裂纹。还有，焊缝接头上，应搭接10到15mm。

(2) During the welding process, sudden interruption and high current should not be used to prevent welding cracks. Also, on the weld joint, it should be overlapped by 10 to 15mm.

(3)焊件在焊接过程中，不能被移动、搬动，或者是被敲击。

(3) During the welding process, the welded parts cannot be moved, moved, or struck.
