先焊炉底板间对接焊缝，由中间往四同辐射对称焊接。
First, weld the butt seams on the bottom plate of the furnace, with radiating and symmetric welding conducted from the central point.
本文提出了一个统一的二维轴对称焊接残余应力场的简化计算模型。
A unified simple model is proposed in this paper for the computation of 2-d axisymmetrical residual stresses of welding.
不同的装配—焊接顺序，焊后产生不同的残余变形，一般是先点固，再进行对称焊接。
Different assembly-welding sequence may result different risidual deformation, we usually take fixup by spot welding first, then take welding symmetrically.
