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。

电焊条焊条药皮的选定，除了探索新渣系外，一般沿用下列几种类型的药皮而进行调整试验。
（1）、典型药皮组成、特性及发展方向
1)、钛型
①特点：含较多量的氧化钛，焊条工艺性能良好，电弧稳定，再引弧方便，飞溅很小，熔深较浅，熔渣覆盖性良好，脱渣容易，焊缝波形特别美观，可进行全位置焊接，尤其适宜于薄板焊接。但是焊缝塑性和抗裂性稍差。随着药皮中的钾、钠、铁粉等用量的变化，可分为高钛钾型、高钛钠型及铁粉钛型等。

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.

Welding wire
Welding wire electrode skin, in addition to the selected medicine explore new slag series outside, general used the following several types of drugs and skin adjustment test.
(1), typical medicine composition, characteristics and development skin direction 1), titanium type
(1) features: contains more amount of titanium oxide, electrode process performance is good, steady arc, then arc starting convenient, splash is very small, the depth is shallow and slag coverage is good, take off to weld waveform special, slag can be beautiful, all position of welding, especially suitable for welding plate. But weld plastic and crack sex is a bit poor. With the medicine in the skin potassium, sodium, such as changes in the amount of iron powder, can be divided into high titanium potassium type, high titanium sodium type and the iron powder of titanium.
