In the use of fixture in welding manipulator, first of all, it should have better manufacturing technology and higher mechanical efficiency; if it is on the same fixture, the form and structure of clamping mechanism and locator are not suitable for more, and it is better to choose only a single power source; if it is used in larger plate welding fixture, then Fixtures should be strong enough in strength and stiffness, especially the stiffness of the whole fixture. Whether it is the accuracy of the structure in shape, size and so on, it will have a greater impact. Therefore, at the beginning of the design, it is best to reserve a certain margin.

Fixtures in different welding machines have different requirements in conductivity, insulation, heat conduction and magnetic insulation. For example, in flash welding and protruding welding, fixtures also need to take into account the use of conductors, while in brazing, fixtures need to have both heat sinks, so the requirements for fixtures are very high; if the fixture needs to be close to the welding position of the welding positioner, it also needs to consider the effect of the operation handle on heat insulation, and prevent splashes from flying out during welding, right? The locator and structure cause surface damage; the whole force point of fixture should be set at the support position of welding, or near the support position, to prevent the occasional phenomenon caused by the support force and clamping force, as well as the support force and gravity.
