| English to Chinese: arc blow welding
General field: Tech/Engineering | Source text - English
Arc blow
Arc blow refers to the metal stream being deflected from its intended path. Rather than follow the shortest path from the electrode to the work, the metal is deflected forward or backward from the direction of travel, or less frequently to the side. Arc blow results in excessive spatter, incomplete fusion, reduced welding speed, and generally lowered weld quality.
Arc blow is caused by either magnetic or thermal conditions in the arc area. Magnetic blow comes from an unbalanced magnetic field surrounding the arc. Magnetic fields are set up in a continuous series of circles perpendicular to the current path. When the fields are unbalanced, the arc bends away from the greater concentration, resulting in arc blow. This condition exists particularly with direct current because the induced fields are constant in direction. It is only minor for ac because the magnetic fields collapse as the current reverses.
Thermal arc blow results from the physics of the electric arc, which requires a hot spot on both the electrode and the workpiece to maintain a continuous flow of current in the arc stream. As the electrode moves relative to the work, the arc will tend to lag behind because it is reluctant to move to a cold spot. With manual weld, thermal arc blow is not likely to become a problem, but with higher speeds of automatic welding, thermal and magnetic arc blow are likely to become more frequent.
Methods of controlling arc blow are:
1. changing to ac current.
2. reducing welding current and keeping arc length to a minimum.
3. placing the ground connection as far as possible from the weld.
4. wrapping the ground cable around the workpiece so that the current will flow to establish a second magnetic field that neutralizes the magnetic field of the arc blow.
Electrode coatings
Electrodes used in manual welding are usually covered with a flux coating that vaporizes in the heat of the arc to form a protective gas(co2). This gas excludes nitrogen and oxygen from the molten metal, thus preventing the formation of undesirable oxides and promoting a smooth flow of molten metal. This form of shielding, now referred to as shielded metal-arc welding(SMAW) or stick-electrode welding, may consist of cellulosics or minerals or a combination of both.
Cellulosic coatings derive their name from the cellulosic materials from which they are made, such as wood pulp, sawdust, cotton, and various other compositions obtained in the manufacture of rayon. The expanding gas furnished by the burning cellulosic material acts to give a forceful digging action to the weld. Properly made, the electrode coating will burn just a bit more slowly than the core wire, forming a cup or crucible at the end of the rod that makes it easier to direct the arc. Cellulosic-coated electrode can be used in any position, but are particularly in vertical, horizontal, and overhead positions.
Mineral coatings are manufactured from natural silicates such as asbestos and clay. By adding oxides of certain refractory metals such as titanium, the harsh digging action of the arc is modified to produce one that is poor and on sheet metal where shallow penetration is desired. A large amount of slag is produced, which serves to protect and control the quality of the deposited metal as it cools. The heavy slag retards the cooling rate of the deposited metal, allowing gas to escape and slag particles to rise to the top. Cooling stresses are reduced and a more homogeneous microstructure results. Because of the large amount of slag produce, the mineral-coated electrode is used most advantageously on downward welding. Downward welding is used in making flat welds and those inclined up to
45°.
The use of iron powder has been a later addition to the electrode-coating field. The use of iron powder brought several desirable effects: after the arc is struck, the metal melts away, leaving a well-defined crucible at the end of the rod that effectively concentrations the heat and gives an automatically consistent arc length. In fact, the electrode may be just slowly dragged over the work since the coating will maintain the proper arc length. The slag that forms over the weld is often self-removing, and the appearance of the bead is improved. It also furnishes more inches of weld per electrode because the iron in the coating goes into the weld. However, because of the heavy coating, there are about half as many rods per pound.

电弧偏吹
电弧偏吹指的是偏离预定轨道的金属流。与通过电极到工件的最短路径不同的是，金属会从运动方向前偏或后偏，或经常不能焊到边。电弧偏吹会产生多余的溅洒、熔化不完全、焊接速度减慢、降低焊接质量等缺陷。
电弧偏吹是由弧区的磁力或热力引起。磁偏吹来自于电弧周围的不平衡磁场。磁场形成在垂直于电流通道的一系列连续的环圈中。当磁场不平衡时，电弧偏离密度值较大的地方，就产生了电弧偏吹。在直流情况下，磁偏吹特别多，因为感应场一直是一个方向。对交流来说磁偏吹很小，因为磁场随着电流换向而失稳。
热偏吹来自于电弧的物理特性，电弧需要在电极和工件两端产生一个过热点来保持弧区电流的连续流动。当电极相对于工件移动时，电弧会滞后，因为它不情愿移向冷点。手工焊时，热偏吹不会成为问题，但在较高速度的自动焊接时，热偏吹和磁偏吹很可能经常出现。
控制电弧偏吹的方法有：①变为交流电；②降低焊接电流，使电弧长度最小；③接地尽可能远离焊缝；④在工件周围缠绕接地电缆，使电流产生一个第二磁场来中和电弧偏吹的磁场。
焊条涂层
手工焊的焊条通常要盖上一层焊剂涂层，它在电弧的热作用下蒸发，产生保护性气体(C02)，这种气体将氮气和氧气与熔融金属隔开，因此不会产生不需要的氧化物，并促进熔融金属的平稳流动。这种形式的保护屏，现在称为有保护屏金属电弧焊接(SMAW)或焊条电极焊接，这种涂层可由纤维素质或矿物质或两者的组合而组成。
纤维质涂层得名于组成它们的纤维材料，如木浆、锯屑、棉花和各种其他的制造人造丝时得到的纤维。燃绕纤维材料得到的膨胀气体提供有力的渗透作用。如制作适当，焊条涂层将比芯部导线燃烧得更慢一些，在电极棒的尾部形成凹杯状，易于引导电弧。纤维涂层的焊条可用在任何地方，但特别适用于垂直、水平焊接和仰焊场合。
矿物质涂层是由天然硅酸盐如石棉和粘土等制成，加入特定的难熔金属（如钛)的氧化物质，电弧的强烈渗透作用可得到修正，产生一种较温和的不太渗透的电弧。当焊接条件差以及焊接薄板金属，需要浅渗透时，可使用这种焊条。这种焊条产生大量熔渣，在金属冷却时保护和控制焊缝金属的质量。太多的溶渣推迟焊缝金属的冷却速率，使气体逸出，熔渣颗粒浮到顶部。冷却应力减少，可得到更均匀的显微结构。因为产生大量溶渣，矿物涂层焊条主要用于俯焊，用于平对焊和那些倾斜的45°的焊缝。
近来将铁粉加入焊条涂层中。使用铁粉也带来了几个需要的结果：电弧形成后，金属熔化，在电极端部留下一个轮廓分明的熔坑，可有效聚热并产生自动稳定的电弧长度。事实上，焊条可在工件上慢慢拖动，因为涂层可保持适当的电弧长度。在焊缝处形成的熔渣经常可自行除去，焊缝的外表可得到改进。因此涂层中的铁粉参与焊接，对每根焊条，它能产生更长的焊缝。然而，因涂层较重，每磅焊条数大约是其他涂层焊条的一半。
