Chế tạo thiết bị đo chi phí thấp dành cho giảng dạy thực hành ngành Hàn dựa trên phương pháp tiếp cận CDIO

Tóm tắt

Manufacturing low-cost measuring equipment for teaching technical disciplines, in general, and welding, in particular, is an essential task of training institutions and schools in the context of limited funding sources to purchase measuring equipment. We have fabricated a low-cost water pressure test kit consisting of a compact water tank, a water pressure pump with a gauge, and a set of cuffs for clamping the quality test weld pieces by water pressure, during the test the water does not overflow along the surfaces, the welds of the product after the water pressure test are checked by the US ultrasonic meter OLYMPUS EPOCH 600 to evaluate price, reference. Through the experimental results, it can be confirmed that self-made equipment is beneficial for use in both classrooms and laboratories to improve practical skills and creativity by CDIO (Conceive-Design-Implement-Operate) method approach from Perceive, Design, Implement, and Operate.
