- Welding Positioners are mechanical devices that hold a work part and provides flexibility for the welder to rotate the workpiece as per the requirement of the welder. It allows the operator to work at a certain angle providing a consistent surface to weld.
- While welding any metal or a component, the high temperatures produced during the process melts the material and a molten metal weld pool is formed.
- The atmosphere is a mixture of gases that can enter the weld pool and react with it causing a variety of issues like porosity, excessive weld spatter, poor weld quality.
- For high production or complex objects fixturing, some additional arrangements are required when compared to simple fixturing
- Something that can quickly get fixed into the fixture and establish a firm holding to the parts to be welded is necessary
- In robotic welding, the post-weld cleanup and spatter removal are greatly reduced, decreasing the downtime between the projects.
- Welding of inaccessible areas of a component, dangerous parts that may be risky to the operator’s life can be done efficiently in less time by robotic welding.
- A checking fixture is a quality assurance tool used in industries to check for the quality of components with complex shapes.
- A checking fixture is similar to a gauge except that it can hold the part it measures. It can accommodate any number of gauging devices while holding the part to be inspected.
- 4 types of welding fixtures are Gas, arc, resistance & laser welding fixtures.
- The main purpose of a fixture is to locate, support and hold the workpiece in position firmly to obtain a precise product from a process.
