Welding robots of their application and classification
By manufacture of details, designs from metal the wide circulation was received by welding. Her apply to connection of metal designs among themselves. In the application of welding, the made details receive a welded seam which in certain conditions, can exceed on a fortress a fortress of the material. Work of the welder is often connected with performance of repeating operations that can lower attention and lead to marriage of performed work. From the economic party of a question application of the competent expert on performance of the same work not rationally, is better to involve the expert on a section where responsible and exact performance of work is required.
Therefore welding the first of processes on manufacture that was automated, namely have introduced robots. The welding robot has found a wide circulation at performance of the same operations. It is applied on automobile manufacture more often. Some automobile concerns have factories on which robots perform the big share of work in manufacture, than the person. Welding robots are applied basically for welding of bodies of cars.
Application of welding robots favourably on batch production of averages and vast scales. On small-scale manufactures their advantage decreases, as will be spent more time for equipment programming, rather than for manufacture. For small-scale manufactures application of the robotised processes in a complex from the several robots united in one transport line is possible, each robot carries out the same operation similar among themselves.
On manufacture welding robots are grouped depending on physical parametres of a detail, namely: the size, the form, a material of a detail, a kind of applied welding, an assortment of details. From material and assortment parametres the structure of manufacture and technological features of work is planned by manufacture. From parametre as the form is planned what mechanisms will be applied to moving of details. From weight of a detail load-carrying capacity of the manipulator miscalculates. For standardization of carried out processes the parametre, that does not change this parameter is a form of. At standardization of carried out processes time for a vectoring of all process of welding of a details decreases.
Robots apply to automation of following kinds of welding:
- submerged arc;
- The arc welding ;
- The point welding;
The best from the listed list of arc welding in robotizing welding manufacture has recommended. At application of electroarc welding all materials move on a tube to a welding place.
