Knowledge Base

Q

The storage of the welding machine belt should be placed in a cool, dry, and ventilated environment, avoiding direct sunlight, high temperatures, and humidity to prevent aging and deformation. Stay away from corrosive gases, liquids, and sharp objects to avoid damage. Store flat or in rolls, without excessive bending or squeezing, to prevent distortion or cracking. The storage environment temperature should be between 10 ℃ and 30 ℃, with appropriate humidity to prevent the material from absorbing water and hardening. prepare

Q

The aging of the belt of the serial welding machine is manifested by surface hardening, loss of elasticity, no rebound when pressed, and easy occurrence of cracks and fissures. The color darkens, becomes brittle, and cracks upon slight bending. Edge wear, burrs, delamination, decreased strength, and easy breakage. During transportation, slipping, deviation, and increased vibration lead to a decrease in positioning accuracy. Holes are prone to blockage, edges are damaged, and the adsorption force is uneven. Increased abnormal noise and temperature rise during operation
