焊接

焊接是通过热施用加入金属零件时采用的技术。热量有助于融化零件，然后再使它们冷却并引起融合。除了熔化要制造的碱金属外，还添加了填充物材料以创建成为关节一部分的熔融材料池。根据配置，制造的件可以比原始材料强。焊接的主要类型包括：1。锻造焊接：这种类型的焊接涉及塑造要固定的零件，加热并锤击以采取预期的形状。尽管也将其应用于某些链条制作过程中，但它被认为是铁匠的工艺。2.电弧焊接：当今大多数焊接过程都属于这一类别。该过程涉及在金属电极和工作人员之间撞击电弧。然后，将熔融金属的微小球从电极转移到焊接接头。请注意，可以使用直流电或交替电流进行电弧焊接。 3. Resistance welding: This welding process involves generating heat by passing current via resistance generated by contact between two metal surfaces. The welding method is preferred because it causes little or no pollution. One example of resistance welding is spot welding used for joining overlapping sheers. 4. Electron beam welding: This method involves bombarding a workpiece with a stream of high-velocity electrons and converting their energy into heat on impact. The heat is so much that the workpiece almost vaporizes through-holes instantaneously. It is preferred when narrow deep penetrations welds are needed on beams. Other types of welding include cold welding that uses press instead of heat, friction welding that uses friction heat, and laser welding that relies on light energy supplied through a laser source. For better results, it is prudent that you use the right welding equipment and the process is done by an experienced person/s.
