Post-weld non-destructive testing inspection
Non-destructive testing methods are commonly used 1.UT (Ultrasonic Test) ——Principle: Sound waves propagate in the material, when there are impurities of different densities in the material, sound waves will be reflected, and the piezoelectric effect of the display element will be generated on th...Read more -
Weld deformation correction
The main components of the steel structure are welded H-shaped steel columns, beams and bracings. Welding deformation often uses the following three flame correction methods: (1) linear heating method; (2) Spot heating method; (3) Triangle heating method. 1. Correct the temperature The following ...Read more -
Weld stress and deformation control
