Abstract:
Because of growing demands in hardware products, automation is necessary in hardware product industries. Welding is very popular and important process of hardware manufacturing industries. Design of automatic welding machine is done for orbital welding to get accurate and precision of welded part and also for increasing the productivity. Applying given constraints like movement of welding torch, work envelope, fixture for holding objects. Various kinematic mechanisms like four bar mechanism etc. are studied to obtain design for holding welding torch and its circular movement. And also various mechanisms are studied to develop holding device for holding the object.
