Working Principle
The Weld Corner Strength Testing Machine applies a controlled compressive or tensile force to the welded corner joint of a window or door frame specimen until failure occurs.
Testing procedure:
- Prepare the welded corner specimen according to the testing standard.
- Secure the specimen using the adjustable fixture.
- Set the required loading speed and testing parameters.
- Apply force continuously through the hydraulic or servo loading system.
- Record the maximum breaking force, displacement and deformation.
- Automatically generate the test report and evaluate weld corner strength.
The results help manufacturers optimize welding quality, improve production processes and verify compliance with quality standards.
