鋼結構的焊接，我們在實施過程中，應事先了解哪些具體內容，這樣操作起來才不至于出錯，這也是焊接人員，在對無錫鋼結構進行焊接時，非常關心的。因此為了更好普及這些知識：

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.作業(yè)條件

1. Homework conditions

(1)要對圖紙很熟悉，并做好焊接技術交底工作。

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

(2)在施焊前，應檢查焊工的上崗證是否在有效期限內，是否能擔當焊接工作。

(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)現(xiàn)場供電條件，應符合焊接用電要求。

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

(4)如果施工溫度低于零攝氏度，那么應先進行預熱，然后再進行操作。

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

2.冬期低溫焊接

2. Winter low-temperature welding

(1)采用電弧焊時，如果環(huán)境溫度低于零攝氏度，那么應對焊接工藝參數(shù)進行適當?shù)恼{整，并遵守常規(guī)的焊接規(guī)定。此外，焊縫和熱影響區(qū)的冷卻，應緩慢進行。

(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)如果風力超過規(guī)定，那么應采取擋風措施。

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

(3)焊接后未冷卻的接頭，應避免與冰雪相接觸。

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

(4)為了防止產(chǎn)生焊接裂紋，對鋼結構焊接時應進行預熱，并控制好層間溫度。

(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.質量標準

3. Quality standards

(1)鋼結構焊接工程的檢驗的劃分，分分為若干個批次，分批進行檢驗。

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

(2)對于碳素結構鋼，在焊接完成后24小時內，要進行焊縫探傷檢驗。

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

4.應注意的質量問題

4. Quality issues to be noted

(1)焊接部位的相對尺寸和位置，應嚴格進行控制，準確無誤后才能進行焊接，焊接時也要精心認真準確進行操作。

(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)焊接過程中，不能突然中斷，不能使用大的電流，以防產(chǎn)生焊接裂紋。還有，焊縫接頭上，應搭接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)焊件在焊接過程中，不能被移動、搬動，或者是被敲擊。

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