Content: Cold welding is one very popular form of welding that works without the need or the presence of heat. To simplify the process, cold welding is the rather effective procedure of joining two metals without the use of thermal or heat energy. To the naked, untrained eye this entire procedure might sound a bit too unbelievable to be true. But, cold welding is a big part of the welding industry and there is no way to deny that. How do we join metals without heat? To understand just how metals can be joined together without heat, we first need to understand just how the process works when you are performing it using thermal energy. The presence of heat within a welding process helps you in making the metal parts plastic enough. Once the parts have become plastic and flexible, the welding process jumps towards diffusing the atoms. The diffusion process either involved the two workpieces you are working with or a completely different medium placed in between. However, contrary to popular belief, you don’t really need heat energy to perform a welding job.
