介绍硼酸注入箱人孔焊缝的结构和其制造工艺过程。图纸要求人孔外圆和简体的坡口夹角为20°,形成的焊缝为20°的区间。制造中遇到两种情况,一种情况是人孔外圆开5°坡口和简体开15°坡口,另一种情况是人孔外圆直坡口和简体开20。坡口。制造中采用立车代替镗床进行加工坡口,立车进行加工采用移动工件形成偏心距,加工中简体的坡口是一边一边逐步加工。针对简体的15°坡口和20°坡口,在立车进行加工时的偏心距计算方法,形成的焊缝15°坡口人孔外径与简体开孔坡口的焊接间隙是从最dq2mm到最大20mm变化的,20°坡口人孔外径与简体开孔坡口的焊接间隙是从最dq2mm到最大18mm变化的。人孔外径与简体开孔坡口大间隙组对焊接中采用工装定位,提出焊接中应注意的问题,为此类产品的加工提供借鉴。
介紹硼痠註入箱人孔銲縫的結構和其製造工藝過程。圖紙要求人孔外圓和簡體的坡口夾角為20°,形成的銲縫為20°的區間。製造中遇到兩種情況,一種情況是人孔外圓開5°坡口和簡體開15°坡口,另一種情況是人孔外圓直坡口和簡體開20。坡口。製造中採用立車代替鏜床進行加工坡口,立車進行加工採用移動工件形成偏心距,加工中簡體的坡口是一邊一邊逐步加工。針對簡體的15°坡口和20°坡口,在立車進行加工時的偏心距計算方法,形成的銲縫15°坡口人孔外徑與簡體開孔坡口的銲接間隙是從最dq2mm到最大20mm變化的,20°坡口人孔外徑與簡體開孔坡口的銲接間隙是從最dq2mm到最大18mm變化的。人孔外徑與簡體開孔坡口大間隙組對銲接中採用工裝定位,提齣銲接中應註意的問題,為此類產品的加工提供藉鑒。

The paper introduces the struckLre and manufacture process for the weldkN seam of the manhole in boric acid injection tank. The manhole cylindrical and the cylinder bevel' s angel is 20° and the formation of the weld seam is 20°. In general, two possibilities occur in the manufacturne process, one case is manhole open 5° bevel and the cylinder open15° bevel. Another case is the manhole with straight bevel and the cylinder open at 20° bevel. Vertical lathe instead of boring machine is used for processing bevel. By moving the workpiece, eccentricity is formed. The cylinder bevel is gradually manufactured from side to side. Considering the cylinder 15° bevel and 20° bevel, the method of calculating the eczentricity in the vertical lathe processing is a critical issue. The shape of weld seam should also be noticed in welding. This article provides reference for the processing of such kinds of product.
