桥架焊接规范要求介绍

一、桥架焊接规范要求介绍
1、 Introduction to Bridge Welding Specification Requirements
关于桥架焊接的规范要求,主要包括以下几个方面:焊接材料的选择和质量要求、焊接工艺的选择和实施、焊接缺陷的检测和评定、焊接接头的外观质量和尺寸精度、焊接接头的强度和耐腐蚀性能等方面。需要根据具体情况和要求进行制定和执行相应的规范和标准。
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.
可以根据桥架的材质、使用环境和焊接的要求等因素选择合适的焊接材料,常用的有电弧焊、气体保护焊和激光焊等技术。同时,还需要考虑焊接工艺参数的控制和质量检测等方面。
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.
针对桥架焊接缺陷的检测和评定,一般可采用无损检测技术,如X射线检测、超声波检测、涡流检测等方法,来检测焊接部位是否有裂纹、气孔等缺陷,并进行评定。

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.
根据所使用的材料、工艺和设计要求不同,桥架焊接接头的外观质量和尺寸精度的要求也会不同,需要具体情况具体分析。
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、室外桥架标准有哪些
2、 What are the standards for outdoor cable trays
室外桥架可以承载较大的电力线路和通信线路,具有耐腐蚀、防震、抗风等特点。同时,它也能适应多种环境,如河流、公路、铁路等,具有灵活性强的优点。
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.
室外桥架的规格体现了桥架的尺寸,桥架规格与要敷设的线缆电缆数量有关,与桥架标准规定的充填率有关系,也决定了桥架的板材厚度。镀锌板桥架表面不能有白锈或其他污垢,国外标准对具体外观缺陷描述的也不是十分清楚,具体项目中如果有对外观的要求在合同中要明确列明。
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.
在桥架行业发展了这么多年之后,人们发展出了桥架需求规格,电气委员会甚定义了一个好多版本的桥架行业标准。桥架板材如果为镀锌板,则板材表面的锌层厚度不能超过桥架标准中规定的厚度,不能有各种擦伤和刮痕,表面不能有各种污渍。
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.
