目前，固定靴之间的垂直位置焊接采用两种相关程序，即电渣焊和电气焊。这些程序在许多方面都非常相似，因此可以在一份报告中对其进行处理，但同时在操作模式上也有明显不同。美国焊接协会（American Welding Society）最近为其制定的官方定义强调了这一差异，将其中一种分类为过程（焊接的基本方式），另一种分类为方法（不同焊接过程的从属变体）。他们认为电渣焊接是一种焊接过程，因此在焊接过程的主图表上表现为一个圆圈。 他们认为，电弧焊只是一种进行气体保护金属极电弧焊或药芯焊丝电弧焊的方法，因此在主图表上不会出现单独的圆圈。然而，在本报告中，这两种材料一起进行了讨论，因为它们在设备、焊接准备方式和焊接顺序上有很大的相似性。

Welding in the vertical position between retaining shoes is presently being practiced by two related procedures, electroslag welding, and electrogas welding. These procedures are sufficiently similar in many respects to warrant their treatment in a single report, but they are at the same time distinctively different in mode of operation. Official definitions recently formulated for them by the American Welding Society emphasize this difference, categorizing one as a process (a basic manner of welding) and the other a method (a subordinate variation of a different process of welding). They consider electroslag welding a welding process, and as such it appears as a circle on the Master Chart of Welding Processes. Electrogas welding they recognize as merely a method of performing either gas metal-arc welding or flux-cored arc welding, and so it does not appear as a separate circle on the Master Chart. Nevertheless, the two are discussed together in this report because they have great similarity in their equipment, in their manner of preparing the work for welding, and in their welding sequence.
