我厂在制造锅炉金属结构时,已开始采用自动与半自动焊接。但由于掌握这项新工艺的时间还很短,在运用过程中还存在着不少问题。本文仅初步总结了在掌握和运用过程中所发生的问题及解决的措施。锅炉金属结构的种类繁多,按其形状可分为梁柱和框架(带盖板或不带盖板)等几种。梁柱类结构绝大部分呈箱形断面,由型钢或板材等组成。这类结构的特点是焊缝长,接头形状简单,一般都为无坡口对接缝和角焊缝,在制造过程中有条件采用自动焊接。
I plant in the manufacture of metal structure of the boiler, has begun to use automatic and semi-automatic welding. However, due to the fact that the new process is still short, there are still many problems in the application process. This article only summarizes the problems in the process of mastery and use and the solutions. Boiler metal structure of a wide range, according to their shape can be divided into beams and frames (with or without cover) and several other. Beam-column structure most of the box-shaped cross-section, composed of steel or plate. Such structures are characterized by long welds, simple joint shapes, and generally no beveled butt welds and fillet welds, with the option of automatic welding in the manufacturing process.
