Costs and trends in welding
There have been massive changes in the industry of welding. Initially, the process of welding would mean large bulky units and massive drawing of power. Also there would be many health issues and very limited geometry on which the welds can be created. However with the advancements in technology, there have been so many changes in the world of welding that today almost anyone can pick it up as a hobby. There are many units available that are portable and make the whole process of welding easy. Also there is great emphasis given on cost saving and these machines are specifically designed to minimize the energy usage in the process of welding. The machines are made for precise welding so that there is less room for error. With development of highly evolved techniques of industrial welding like the laser welding or plasma arc welding the process of automating a welding line has become relatively simple.
