Resistance welding process, also known as spot welding, is recommended and broadly used for metal fusion. it consists basecally of generating heat by passing electrical current through an electrical resistance. However, metals have different electrical and mechanical characteristics of one another, and, specifically in relation to the fusion of two or more components by resistance welding, it can be affirmed that some combinations are more susceptible to form alloy than others. In particular, non-ferrous metals (eg. silver, copper, brass, among others) are more difficult to weld for being more conductive, and then, demand a more extremelly accurate control of welding parameters. Isontron acts strongly in this market segment, producing machines, equipments and accessories for resistance welding, which demands princinpally precision, resources and quality. Projects are elaborated and executed indoors by technician and engineers highly qualified and with expertise in the area. The increasing investiment in technology by this company is a prepoderant factor to the success it has obtained in this market segment, allowing the development of new equipments and cosequently enlarging the degree of satisfaction and reliability of its clients and partners. Among the products the company offers, there is a highlight to Medium-frequency welding system and to automated solutions, or special machines, which are developed in partnership with the clients based on specific applications. Clients who already have a resistance welding machine and want to enjoy this technology can obtain a Welding Controller and/or a Welding Monitor to control parameters and monitoring quality respectively.
