鋼結(jié)構(gòu)(工程結(jié)構(gòu))工程質(zhì)量的優(yōu)劣，主要取決于人為，施焊設(shè)備、施工工藝、焊材、施焊者技術(shù)水平和環(huán)境因素(factor)等方面，所謂人、機(jī)、料、法、環(huán)之五大要素，故在鋼結(jié)構(gòu)(工程結(jié)構(gòu))工程實(shí)施過程中，很多情況下應(yīng)在特別注意，或進(jìn)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(yù)熱、后熱處理及焊 接工藝參數(shù)等，是否按規(guī)定進(jìn)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(xiàn)場拼裝的場地平整性，壓實(shí)度和使用的臨時(shí)支撐胎架、馬櫈的強(qiáng)度（strength)、剛度及穩(wěn)定（解釋:穩(wěn)固安 定；沒有變動(dòng))性(Thestabilityof)等是否能滿足施工工藝和鋼構(gòu)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(yīng)有預(yù)起拱的構(gòu)件，其起拱值是否符合設(shè)計(jì)要求進(jìn)行了復(fù)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(jié)構(gòu)(工程結(jié)構(gòu))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(xiàn)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(guī)定的范圍內(nèi)施焊。

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

六、在低溫、風(fēng)雨天氣環(huán)境下的施焊操作是否已有滿足工藝質(zhì)量的相應(yīng)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(guī)定進(jìn)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(jìn)行了專門的清理，是否已考慮（consider)并采用了使焊 接應(yīng)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(jié)構(gòu)(工程結(jié)構(gòu))設(shè)計(jì)要求。

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

十、設(shè)計(jì)要求應(yīng)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.
