Abstract:

This paper is a description of an alternative fixture for the edge preparation of elbows and pipes before welding. The welding will not penetrate the cross section of the pipe if the thickness of the pipes is more than eight millimeter, so edge preparation is done before welding. Fixtures are used to hold the pipes during the process of edge preparation. This paper deals with two major issues from the design of previous fixtures.Requirement of manual handling of the part.Precise rotations are not possible. The fixtures being used currently require more setting up time and they require manual h

The reconfiguration and the capacity of rapid adjustment of automotive welding fixture are the main obstacle to the development cycle and the modified automotive products. A set of reconfigurable fixture has been designed tentatively for a series of car product development. It is consisted of the fixture plate with holes in base stations, the three-dimensional adjustment of bearings and the standard fixtures, which show the character of a quick installation location, easy to adjust, shorten the development cycle and so on.

Because of the complex structure of the oil collector, the manufacturing process requires manual adjustment for groups of fixtures, and then the thin circular components are welded together by TIG (Tungsten Inert-Gas) welding. This process leads to the low productivity of the oil collector, and the quality is difficult to maintain.

Abstract The process time and cost of a weld product depend largely on the decisions to select the weld orientation and relevant fixtures. Such decisions must be made at the early stages of the design process so that necessary design changes can easily be made to achieve an optimal design solution. However, traditional CAD and CAPP systems cannot support weld product design and welding process planning unless detailed design information is available.

Several conceptual designs of the key component, the lockable joint, are presented. Unlike existing mechanisms, which can lock the joint in a finite number of positions, the proposed solution is a stepless device. Once locked, the joint can resist high torque in both directions. T

Weld shrinkage data models were developed for thin uniform and complex ship-panels to predict in-plane shrinkage. The complex features in the thin panels include cutouts, inserts, multiple thicknesses, and non-rectangular shaped panels.

It was observed that the inserts induced additional butt joint across-weld and along-weld shrinkage and did not affect the fillet-weld shrinkage. The weld shrinkage data mod
