The effect of welding flame heating on the weld structure and the weld heat affected zone

welding

weld heat affected Zone The welded joint can be divided into three main zones having different micro structures: base metal zone; heat affected zone; and a weld seam weld zone. In gas welding, due to slow heating , the heat affected zone (near- heat zone) is larger than in the case of arc welding . The thermal influence zone has several structural sections caused by the heating temperature in the range of 450-1500 ° C and differing in the shape and structure of the grain. The thermal influence zone consists of the following sections: incomplete fusion overheating normalization incomplete re-crystallization[…]

what is pipeline definition?

piping and pipeline

understanding a pipeline A pipeline is a structure designed to transport liquid, gaseous, and solid (bulk) products. Pipelines consist of straight sections of pipes tightly interconnected, parts, shut-off and control valves, instrumentation, automation, supports and suspensions, fasteners, gaskets and seals, as well as materials used for thermal and anti-corrosion insulation. Pipeline parts are the connecting parts that are used in the construction of pipelines for various purposes, necessary for bending, bending, bending, changing the diameter of the pipes and in the case when the pipeline is temporarily not used. Parts are connected when installing the pipeline, as a rule, butt[…]
