鋼結構(工程結構)工程質量的優劣，主要取決于人為，施焊設備、施工工藝、焊材、施焊者技術水平和環境因素(factor)等方面，所謂人、機、料、法、環之五大要素，故在鋼結構(工程結構)工程實施過程中，很多情況下應在特別注意，或進行有用地防范（解釋:防備、戒備)。

The quality of steel structure (engineering structure) engineering mainly depends on the man-made, welding equipment, construction technology, welding materials, welding technical level and environmental factors. The so-called man, machine, material, method and environment are the five elements. Therefore, in the process of steel structure (engineering structure) engineering implementation, special attention should be paid or useful prevention should be carried out in many cases Alert).

一、對采用的鋼材、焊材、焊 接方法和位置（position)、接頭形式、施焊預熱、后熱處理及焊 接工藝參數等，是否按規定進行了焊 接工藝評定。

1、 Whether the welding procedure qualification has been carried out for the steel, welding material, welding method and position, joint form, welding preheating, post heat treatment and welding process parameters.

二、現場拼裝的場地平整性，壓實度和使用的臨時支撐胎架、馬櫈的強度（strength)、剛度及穩定（解釋:穩固安 定；沒有變動)性(Thestabilityof)等是否能滿足施工工藝和鋼構件拼裝后的精度（度）要求。

2、 The site evenness, compactness, strength, rigidity and stability of temporary support jig and saddle used for field assembly (explanation: stable and stable; construction cost: 1; Whether the stability can meet the requirements of construction technology and accuracy of steel components after assembly.

三、應有預起拱的構件，其起拱值是否符合設計要求進行了復核（審查核對)。

3、 If there should be pre arched components, whether the arched value meets the design requirements has been checked (checked).

四、鋼結構(工程結構)拼裝中，是否已注意腹桿與主桿或主管與鋼球的沒有偏心現象再施焊。

4、 During the assembly of steel structure (engineering structure), whether attention has been paid to whether there is no eccentricity between web member and main member or between main pipe and steel ball before welding.

五、巡查焊工是否都具有上崗證，并在規定的范圍內施焊。

5、 Inspect whether all welders have work license and carry out welding within the specified scope.

六、在低溫、風雨天氣環境下的施焊操作是否已有滿足工藝質量的相應措施（指針對問題的解決辦法)。

6、 Whether the welding operation in low temperature and rainy weather has the corresponding measures to meet the process quality (the solution to the problem).

七、焊材是否匹配，焊條是否按規定進行烘干后再使用。

7、 Whether the welding materials match, and whether the welding rod is dried according to the regulations before use.

八、焊 接縫坡口部位施焊前是否已對銹跡、泥污或誤涂的油漆進行了專門的清理，是否已考慮（consider)并采用了使焊 接應力和焊 接變形很小的方法和施焊工藝。

8、 Whether the rust, mud or mistakenly painted paint has been specially cleaned before welding at the groove of welding joint, and whether the method and welding process to minimize welding stress and welding deformation have been considered.

九、焊 接縫間隙是否符合鋼結構(工程結構)設計要求。

9、 Whether the welding gap meets the design requirements of steel structure (engineering structure).

十、設計要求應使用的襯鋼或墊圈是否已襯放到位后再施焊。

10、 Whether the steel lining or gasket required by the design has been lined in place before welding.
