橋架焊接規范要求介紹

一、橋架焊接規范要求介紹
1、 Introduction to Bridge Welding Specification Requirements
關(guān)于橋架焊接的規范要求,主要包括以下幾個(gè)方面:焊接材料的選擇和質(zhì)量要求、焊接工藝的選擇和實(shí)施、焊接缺陷的檢測和評定、焊接接頭的外觀(guān)質(zhì)量和尺寸精度、焊接接頭的強度和耐腐蝕性能等方面。需要根據具體情況和要求進(jìn)行制定和執行相應的規范和標準。
The specification requirements for bridge welding mainly include the following aspects: selection and quality requirements of welding materials, selection and implementation of welding processes, detection and evaluation of welding defects, appearance quality and dimensional accuracy of welded joints, strength and corrosion resistance of welded joints, etc. Corresponding specifications and standards need to be developed and implemented based on specific circumstances and requirements.
可以根據橋架的材質(zhì)、使用環(huán)境和焊接的要求等因素選擇合適的焊接材料,常用的有電弧焊、氣體保護焊和激光焊等技術(shù)。同時(shí),還需要考慮焊接工藝參數的控制和質(zhì)量檢測等方面。
Suitable welding materials can be selected based on factors such as the material of the bridge, usage environment, and welding requirements. Commonly used technologies include electric arc welding, gas shielded welding, and laser welding. At the same time, it is also necessary to consider the control of welding process parameters and quality inspection.
針對橋架焊接缺陷的檢測和評定,一般可采用無(wú)損檢測技術(shù),如X射線(xiàn)檢測、超聲波檢測、渦流檢測等方法,來(lái)檢測焊接部位是否有裂紋、氣孔等缺陷,并進(jìn)行評定。

For the detection and evaluation of bridge welding defects, non-destructive testing techniques such as X-ray testing, ultrasonic testing, eddy current testing, etc. can generally be used to detect and evaluate the presence of cracks, pores, and other defects in the welding area.
根據所使用的材料、工藝和設計要求不同,橋架焊接接頭的外觀(guān)質(zhì)量和尺寸精度的要求也會(huì )不同,需要具體情況具體分析。
According to the different materials, processes, and design requirements used, the requirements for the appearance quality and dimensional accuracy of bridge welding joints will also vary, and specific analysis is required.
二、室外橋架標準有哪些
2、 What are the standards for outdoor cable trays
室外橋架可以承載較大的電力線(xiàn)路和通信線(xiàn)路,具有耐腐蝕、防震、抗風(fēng)等特點(diǎn)。同時(shí),它也能適應多種環(huán)境,如河流、公路、鐵路等,具有靈活性強的優(yōu)點(diǎn)。
Outdoor cable trays can carry large power and communication lines, and have characteristics such as corrosion resistance, shock resistance, and wind resistance. At the same time, it can also adapt to various environments, such as rivers, highways, railways, etc., and has the advantage of strong flexibility.
室外橋架的規格體現了橋架的尺寸,橋架規格與要敷設的線(xiàn)纜電纜數量有關(guān),與橋架標準規定的充填率有關(guān)系,也決定了橋架的板材厚度。鍍鋅板橋架表面不能有白銹或其他污垢,國外標準對具體外觀(guān)缺陷描述的也不是十分清楚,具體項目中如果有對外觀(guān)的要求在合同中要明確列明。
The specifications of the outdoor bridge reflect the size of the bridge, which is related to the number of cables and cables to be laid, the filling rate specified in the bridge standard, and also determines the thickness of the board of the bridge. The surface of galvanized sheet bridge frames should not have white rust or other dirt, and foreign standards are not very clear about the specific appearance defects. If there are requirements for appearance in specific projects, they should be clearly listed in the contract.
在橋架行業(yè)發(fā)展了這么多年之后,人們發(fā)展出了橋架需求規格,電氣委員會(huì )甚定義了一個(gè)好多版本的橋架行業(yè)標準。橋架板材如果為鍍鋅板,則板材表面的鋅層厚度不能超過(guò)橋架標準中規定的厚度,不能有各種擦傷和刮痕,表面不能有各種污漬。
After so many years of development in the cable tray industry, people have developed cable tray demand specifications, and the National Electrical Commission has even defined many versions of cable tray industry standards. If the bridge plate is galvanized, the zinc layer thickness on the surface of the plate should not exceed the thickness specified in the bridge standard, and there should be no scratches or scratches, and the surface should not have any stains.
