Product Introduction

The molten metal droplet impact performance tester is developed according to the EN 348 and ISO 9150 testing standards, and meets the requirements of the domestic GB8965.2-2009 "Welding protective clothing" and GB/T 17599-1998 "Determination of resistance to molten metal impact performance" testing standards. The testing principle is to use a welding gun to melt the welding wire strip, and when the dripping material causes the temperature of the calorimeter on the back of the fabric to rise by 40 ℃, measure the number of molten metal droplets that fall.

Performance characteristics

• 1. The molten metal droplet impact performance tester includes a burner, a sample frame, a welding strip drive device, a burner flow controller, a human-machine interface display device, etc;
• 2. Oxygen acetylene welding torch is used to melt metal strips, with a welding nozzle diameter of (1.2 ± 0.1) mm;
• 3. Adopting a stepper motor to drive the metal strip, and the operating speed of the metal strip can be set;
• 4. Melt droplet guiding mechanism, coated with high-temperature anti sticking guide groove, with an angle of 45 degrees;
• 5. Fabric temperature sensor device, used to measure the temperature rise on the back of the sample;
• 6. The counterweight copper hammer device is used to set the pre tension of 175g ± 0.5g on the fabric;
• 7. The temperature rise data can be automatically recorded, and the number of molten droplets can be recorded by the testing personnel themselves.
