A welding fixture is used to position product parts for welding. This secures the geometry of the product parts. Welding Fixtures are tools designed to be used by a human welder to complete a welding process, whether it is completing a full weld or tack welds only. The fixtures may be automated with pneumatic clamping, or the fixtures may be able to use manual clamping for effective part holding. The main purpose of a fixture is to locate, support and hold the work piece in position firmly to obtain a precise product from a process.
A welding fixture is designed in a way to support and locate the components to be welded to avoid distortions and weld stresses. It is obvious that each welding operation requires a distinct welding fixture according to our desired requirements. A fixture generally holds the part during welding, but there is a chance of the part being distorted after the removal of the fixture. Hence some stress-relieving and other post-processing operations can be performed to prevent weld distortions. A welding fixture is the one that makes work easier for tools, reduces lead time, improves productivity and quality of the welded parts without any distortion.
