摘要
叙述了在二段式煤气炉的主要受压件水套上,采用了单面焊双面成型技术,可靠地解决了环缝的反面焊接问题,成功地把CO_2焊封底技术用于生产。
The paper introduces the technique on single side welding with bead forming on both sides which makes the root pass of weld on water jacket shell that constiute the main pressure vessel of coal gas generator. By using CO_2 arc welding to seal root pass of girth weld, the difficults of bead forming on backside is overcome. The technique is applied into production successfully.
