Automatic welding process factors affect Pipeline Analysis

随着国民经济的发展和我国钢产量的提高,低温钢的研发和应用备受重视,如西气东输管道、青藏铁路、石化工业的各种容器如液化石油气、液氨、液氧、液氮的生产及存储设备以及矿业、建筑施工和运输等用的仪器和设备等均有低温钢的应用,可见低温钢的应用越来越广泛。本文对影响低温钢焊接的因素进行了分析。

With the development of national economy and the improvement of steel production in China,the research and development and application of low-temperature steel have been paid much attention,such as the West-East Gas Pipeline,the Qinghai-Tibet Railway and the petrochemical industry,such as liquefied petroleum gas,liquid ammonia Oxygen,liquid nitrogen production and storage equipment;and mining,construction and transportation and other equipment and equipment are lowtemperature steel applications,showing the application of low-temperature steel more and more widely.In this paper,the factors influencing the welding of low temperature steel are analyzed.
