焊接材料与焊接工艺的制定准则在不锈钢转轮的焊接中,对于不同的转轮材料,正确地选用焊接材料和合理地制定焊接工艺,是确保转轮焊接质量的关键。手弧焊时,焊接材料和焊接工艺的确定,主要视转轮材料的焊接性、转轮的尺寸秘焊接位置等因素的不同而各有差异,其基本准则是:焊接材料的选择应在保证焊接接头机械性能满足设计要求的前提下,具有良好的工艺性能;应以合理的焊接顺序、对称的焊法、方便的焊接位置和最短的焊接工期,來制定焊接工艺准则。当转轮的上冠、下环、叶片采用非同质材
Welding materials and welding process development guidelines In the stainless steel runner welding, for different runner materials, the proper selection of welding materials and reasonable development of the welding process is to ensure the quality of runner welding key. Hand arc welding, welding materials and welding technology to determine, mainly depending on the runner material of the weld, the size of the size of the rotor mystery welding position and other factors vary, the basic criteria are: the selection of welding materials should be guaranteed Welding joint mechanical properties to meet the design requirements of the premise, with good process performance; should be a reasonable order of welding, symmetrical welding method, the location of the welding and the shortest welding schedule to develop the welding process guidelines. When the runner crown, the next ring, the use of non-homogeneous material leaves
