It is perhaps possible that welding will soon be a thing of the past, in some situations at least and those situations are where welding has been used to join sheets of metal. Welding may soon not be used for joining sheets of metal as a newer, safer process has been patented by the Jurado Tools Company and that process is known as clinching.
This newer process is used in clinching sheet metal together and creates a join which is not only safer but is also impervious to any weather conditions and is unaffected by any chemical reactions. Although sheets of metal could be joined in the past by using rivets instead of welding them, clinching is far easier and more resilient than riveting. This means that by adopting the clinching process, many industries can save money on the health and safety aspects that welding requires and also on the quality assurance which riveting requires.
These savings are not something that has been missed by kitchen appliance manufacturers or automotive manufacturers who have already started to use the process in many of their plants. The medical profession has also realized the potential clinching could have in their field and so as well as already using the process in some circumstances, they are also doing studies to see if it can be used in a wider area. The railroad and aerospace industries are considering using clinching in their industries but first want to wait and see the results of further tests that they have to be carried out on the process. As the joins in the sheet metal are impervious to weather and chemicals when clinching is used, the process could be of considerable use within the oil and gas industries which up to now, have often had problems with joins in their cross country pipelines.
So what is this process that could see the end of many welding tasks?
Clinching is a process that can join sheets of different metals together without the use of screws, rivets or welding of any kind and it achieves this by applying pressure, through a die, to the metals to be joined. Under this pressure the metal sheets combine to form what is known as a button and that button secures the two or more sheets of metal tightly together and cannot be affected by rain or chemicals.
For two sheets of metal a die with a round point is used to apply the pressure to the metal but if more than two sheets are to be joined together, a trapezoidal point is better. Although the dies rarely differ, there a number of different clinching machines that can be used depending on the size of the job and the location where the job is to be completed. For manufacturers there are large clinching machines which stay in one place but for clinching in more remote areas there are more mobile clinching machines and then there are other machines for use with irregular shaped metal sheets.
