What is a welding tensile testing machine?
In the fields of industrial manufacturing and materials science, welding tensile testing machines are key equipment used to test the strength of welded joints. With the recent increased focus on quality control in the manufacturing industry, welding tensile testing machines have become one of the hot topics. This article will introduce in detail its definition, working principle, application scenarios and comparison of common models on the market.
1. Definition of welding tensile testing machine
The welding tensile testing machine is an instrument specially used to measure the strength, ductility and fracture characteristics of welded joints under tensile force. It evaluates whether the welding quality meets standard requirements by simulating the tensile conditions in actual working conditions.
2. Working principle
The testing machine applies axial tension to the welded sample through a hydraulic or motor drive system, while high-precision sensors record load and displacement data in real time. The data is processed by software to generate a stress-strain curve to analyze the welding performance.
