YD-R是一种复合物制造的熔剂，用量应为YD焊条重量的2％。 用途：YD型焊条主要用于堆焊石油、矿山、采煤、地质、建筑等工业中一些严重磨损或兼有切削的工件。如：铣鞋、磨鞋、扶正器、扩孔器、钻杆接头、水力割刀、刮刀片、刨煤机刨刀、取芯钻头、打桩钻头、螺旋钻头等。 堆焊工艺：YD型焊条是采用氧—乙炔火焰进行堆焊，使用的气焊焊咀应比普通气焊碳钢所用的焊咀大。火焰应调成中性或稍偏碳化焰。中性焰焰心的尖端位置应严格控制，不能接触到硬质合金颗粒和工件表面，以免过烧，也就是比普通气焊时焊咀提的要高，这一点是影响堆焊层耐磨寿命的关键，切勿忽视。 堆焊时应尽量采用平焊位置，其它位置堆焊时应采用适当的胎具。 工作场地必须通风良好，以免有害健康。 规格：YD型焊条根据硬质合金颗粒大小，分为：以下八个等级供货：
YD型硬质合金堆焊焊条的堆焊工艺 该焊条采用氧乙炔堆焊。操作工艺如下： (1)清理工件，使被焊工件表面露出金属光泽。 (2)取平焊位置进行堆焊，为此可使用适当的胎具为控制堆焊层厚度，可利用限厚块。 (3)用中性焰预热，焰心勿接触工件表面，距离以25mm为宜。 (4)当工件加热到适当温度时，即可在待堆焊表面涂一层专用焊剂，如熔剂预热得合适，熔剂就会起泡沸腾，此时工件表面的氧化物将被熔剂清除，再继续加热至溶剂布满被堆焊的表面并呈透明液体状态时，表明可开始堆焊打底焊层。 (5)堆焊打底焊层，采用中性焰，用打底焊条尖端不断搅动熔剂，并随之熔化，焊咀不断运行，其运行速度恰好与打底焊条的焊速度相等．要确保熔剂保持在工件表面上。当打底过程结束时，堆焊表面应形成一薄层平滑的打底合金，其厚度约lmm左右为宜。如预热温度不足时，熔融的打底层金属不能流平，并在工件表砸上形成小球或凸起。 (6)堆焊硬质合金焊层。在打底合金层上面，用YD型焊条堆焊，使用中性焰(可稍偏碳化焰)焊咀均匀平稳的在工件表面上移动，火焰对着合金焊条加热(注意不可使焰心尖端接触合金颗粒)，使焊条中胎体合金熔化，随之硬质合金颗粒也一同落下。在熔化的胎体金属凝固之前，要把颗粒安排好，可用左手拿着的合金焊条拔弄，或另一人手持一根打底焊条或石墨棒作拔棍，在一傍迅速拨弄颗粒，使之排列均匀整齐。堆焊层厚度按设计要求控制。 (7)工件堆焊完后，放在不通风的地方，缓慢冷却，不可急冷，有条件可用石棉毡盖上。 (8)工件冷却到室温后，如果有需要，可把堆焊面磨到要求尺寸和形状。 (9)清理工件，去除所有飞溅，熔渣等。 堆焊操作方法正确，堆焊层质量满意的标志是：待冷却后，堆焊层表面呈发亮的金黄色，堆焊层胎体合金与基体金属结合良好，合金颗粒排列紧密，且均匀、牢固的焊嵌在胎体金属里。 过热或过烧的标志是：冷却后胎体金属发红，合金颗粒露出黑色表面，其后果是合金颗 粒的工作性能受损，影响使用寿命。 加热不足的标志是：冷却后，呈无光泽的银灰色，胎体合金与基体金属结合不良，堆焊后 的工具运转时整 美国泰克罗伊、奥地利伯乐、德国伯乐、赫伯特HOBART、德国蒂森、德国Cor o dur、德国UTP、法国SAF、韩国现代、美国阿克泰克、美国哈里斯HARRIS、美国万能焊条、日本日亚焊条、日本神钢焊条、瑞典伊萨ESAB、瑞典阿维斯塔、瑞士奥利康、意大利TFA、英国曼切特条。 不锈钢用药芯焊棒 种类 ESAB 牌号 技术标准 熔敷金属力学性能 熔敷金属化学成分（％） 不锈钢用焊条 Z308铸铁焊条 符合 GB EZNi-1 说明:Z308是纯镍焊芯、强还原性石墨型药皮的铸铁焊条，施焊时，焊件可不预热，具有良好的抗裂性能和加工性能。镍价格昂贵，应该在其它焊条不能满足时才可选用。交直流两用。 用途:用于铸铁薄件及加工面的补焊，如发动机座、机床导轨、齿轮座等重要灰口铸铁件。 熔敷金属化学成分(%) 化学成分 C Mn Si S Ni Fe 其它元素总量 保证值 ≤2.00 ≤1.00 ≤2.50 ≤0.030 ≥90 ≤8 ≤1.00 参考电流(AC、DC+) 焊条直径(mm) φ2.5 φ3.2 φ4.0 φ5.0 焊接电流(A) 50~100 70~120 110~180 160~190 注意事项: 上海斯米克焊条 Category Trade- Equivalent to China Standard Characteristics & application Equivalent to AWS Hard-surfacing 硬 面 堆 焊 D 667 EDZCr-B-15 HRc≥48.
