电焊条 焊芯的设计主要考虑焊条直径和焊条技术要求。焊条技术要求包括理化性能和合金元素的过渡等。当前国内焊条有数百种，其中大多数品种系选用H08A 焊芯，其化学成分见表 1，借助焊条药皮过渡合金元素，以获得各种不同用途的焊条。但是，对于不锈钢，镍基铸铁焊条，有色金属焊条则是采用专用的特殊焊芯。

Welding wire welding core design main consideration electrode diameter and electrode technical requirements. Electrode technical requirements including the physical and chemical properties and alloy elements of the transition, etc. The current domestic electrodes have hundreds of varieties, most of them in H08A welding, its core selection chemical composition see table 1, with the electrode medicine alloy elements, with skin transition to obtain a variety of different USES of rod. But, for stainless steel, cast iron, nickel-based electrode non-ferrous metal electrodes is adopted dedicated special welding core.
