Different grades of joints have different quality inspection standards.
The quality standards of joints include joint strength standards, workpiece size requirements, the size and number of internal and external defects in the joint, the number of allowed repairs, and other special performance requirements.
Semi-automaticButt welding machineWhat are the specific requirements?
Let’s take a look with the editor of Xinxing Welding After the semi-automatic copper rod butt welding machine is welded, the following methods are generally used to randomly check the quality of the joints.
Appearance inspection, location, size and surface quality of welds.
Ultrasonic inspection to see if there are large inclusions, pores, shrinkage cavities, oxide scale, etc.
Metallographic inspection to see whether there is complete fusion and thick band structure, etc.
Bending test to see the bending resistance of the joint 5.
Strength test to see the strength and plasticity, torsion resistance and fatigue capacity of the joint.
Impact test to see whether the joint’s ability to withstand impact loads meets the standard.
