Welding rods are a common welding material commonly used to make various types of metal welding. Since the electrode will be exposed to a high temperature environment during the welding process, high-low temperature resistance tests are required to test the welding performance and durability of the electrode at different temperatures. This test can test the electrode coating, weld shape, mechanical properties and other key characteristics of the electrode, so as to ensure the welding effect and stability of the electrode at different temperatures. In addition, the high-low temperature resistance test can also test the moisture-proof, anti-oxidation, anti-corrosion and other properties of the welding rod, so as to ensure that the welding rod will not lose its welding effect and performance due to changes in the external environment during long-term storage and use, and ensure welding quality and safety sex.
The high-low Temperature Test Chamber can be used for high-low temperature resistance tests of welding rods to test the performance and reliability of welding rods in high-low temperature environments. The following are the test steps of the high-low Temperature Test Chamber in the high-low temperature resistance test of welding rods:
Preparation: Check whether the Test Chamber and temperature controller are working normally, and set the temperature range and heating and cooling rate of the Test Chamber according to the test requirements. Prepare electrode samples, noting their size and location.
Sample installation: place the electrode sample to be tested in the test box, and fix the position and direction.
Test operation: Turn on the Test Chamber and temperature controller, and set the temperature range and heating and cooling rate of the Test Chamber. Raise the temperature of the Test Chamber to the set temperature range, keep it for a period of time, and then cool down to the set temperature. During the test, record the temperature change inside the Test Chamber, and pay attention to observe the performance change of the electrode sample.
Evaluation of test results: After the test, take out the electrode sample and observe whether there is deformation or cracking in its appearance. At the same time, parameters such as weld quality and welding strength of the electrodes are tested and evaluated. Through the evaluation of the test results, the tolerance and stability of the electrode in the high-low temperature environment can be judged.
Beichao reminds you: the welding rod should be cleaned and dried before the test, so as not to affect the test results. During the test, the temperature range and heating and cooling rate inside the Test Chamber should be strictly controlled to ensure the accuracy and reliability of the test. At the same time, the Test Chamber should be cleaned and maintained after the test to prolong its service life.
