Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically a pipe weld corner strength tester. Background Technology

[0002] Weld strength testers are generally industrial instruments used to determine the weld strength of profiles, doors and windows. Doors and windows with welds are placed directly on a tray inside the casing. A screw or hydraulically powered pressure mechanism applies pressure to the workpiece under test until it is damaged and the instrument reacts to the change in pressure value. However, there is currently no dedicated testing equipment for weld strength testing of excess pipes and fittings on the market.

[0003] The weld strength test of pipes or fittings differs from that of profiles. Profiles, due to their structural characteristics, can mostly be placed directly inside the instrument without clamping and await pressure. However, pipes are cylindrical and cannot stand independently on a tray for testing. This necessitates the design of specialized clamping mechanisms to hold the pipes for weld strength testing. Moreover, the required clamping mechanism specifications vary depending on the pipe's outer diameter, and a single fixed clamping mechanism cannot meet the clamping requirements.

[0004] Therefore, the inventors sought to solve the problem of designing a testing instrument that could clamp pipes of various specifications, adjust the angle for testing various angles, and be suitable for testing pipe weld angles. Utility Model Content
