Large storage tank ceramic backing welding construction method
The invention provides a large storage tank ceramic backing welding construction method, and relates to the technical field of welding. The method comprises the following steps: preparation before welding, wherein impurities on the surface of a workpiece are removed, and comprise one or the combination of oil stains, metal filings and an oxidation film; backing pasting, wherein specifically ceramic backings are tightly installed on the workpiece in an attached mode, and the ceramic backings are mutually and tightly pushed to be connected in an inclined mode; and welding, wherein specifically, the workpiece is welded through argon arc single-surface welding and priming layer welding. According to the method, a ceramic backing is used as a lining support, so that a welding seam is forcibly formed, back gouging, overhead welding and operation in a narrow and closed environment are avoided, the labor intensity of a welder is relieved, and the welding quality is improved; a welding wire is used as an electrode for argon arc welding, and the allowed current density is high, so that the penetration depth is large, and the deposition speed is high; the production efficiency is higher than that of TIG welding, and the deformation of a thick and large weldment is smaller than that of TIG welding; and the ceramic backing is matched with melting and argon arc welding, so that the welding efficiency and the welding quality are remarkably improved.
本发明提出了一种大型储罐陶瓷衬垫焊施工方法，涉及焊接技术领域。该方法包括以下步骤：焊前准备，清除工件表面的杂质，所述杂质包括油污、金属屑和氧化膜中的一种或其组合。衬垫粘贴，将陶瓷衬垫紧密贴合地安装于所述工件上，陶瓷衬垫和陶瓷衬垫斜接处相互推紧。焊接，采用氩弧单面焊打底层焊对工件进行焊接。该方法通过陶瓷衬垫作为衬托，使焊缝强制成形，避免了清根、仰焊及狭窄封闭的环境内作业，减轻了焊工劳动强度，提高焊接质量；同时，氩弧焊使用焊丝做电极，允许使用的电流密度较高，因此熔深大，熔敷速度快；生产效率比TIG焊高，厚大焊件变形比TIG小；陶瓷衬垫配合熔化及氩弧焊焊接，无论是焊接效率，焊接质量有显著的提高。
