摘要
几种抗裂性试验和焊接性能试验表明,进口LT50钢的抗裂性能和焊接性能良好。如采用较小线能量焊接并进行焊道回火,即使球罐的壁厚达42～50mm,焊后也无需再进行整体消除残余应力热处理。
Several tests of cracking resistance and welding ablity on imported LT50steel show good re- sults, that is, if less linar energe welding and welded seam temper are used in spherical tank, heat treatment of eliminating residual stress with whole unit is not neccessary even if wall thickness of the tank is 42-50 mm.
