摘要
Abstract
Describes the three different welding technologies of applied to the steel currently by analyzing the weldability of Cr5Mo steel.It can be proposed that welding with the same materials as much as possible in order to avoid joints early failure in the operation and reduce welding cost when it has the availability of post weld heat treatment conditions and case of large-scale welding by comparing the performance differences of welded joints obtained and the implementation features with the three welding technology.If in the absence of heat treatment conditions or less maintenance in the field.it is also can be welded with different materials. However,we recommend using the new low-Cr high manganese AR617 weld rod to weld Cr5Mo so as to ensure that it will not low ductile fracture in the joints, the weld rod has excellent welding technology .Through joints sampling observation in the production practices and 44 000 hours service,performance is stable,fully meet the production requirements,the welding technology conditions is relatively simple.关键词
