What are the basic contents of nondestructive testing of crane girder?
The main beam is the load-bearing component of the whole crane, so its importance can be imagined. We must ensure that the main beam of the crane meets various design requirements. In order to meet this condition, it is necessary to carry out nondestructive testing on the main beam of the crane. Specifically, what are the testing contents?

The following is a brief introduction

The main beam is made of steel plate as raw material and through welding process. Therefore, in addition to steel plate material, there are strict requirements for welding quality. The steel plate material can be shown through the relevant performance, so as long as the main beam is tested in terms of hardness, strength, impact resistance, corrosion resistance and so on. All right.
Considering that the welding process of the main beam is relatively complex and prone to various defects, the next content of the inspection. It is aimed at all kinds of defects, and detects all kinds of defects or cracks, so as to eliminate the problems caused by welding. After many tests to ensure that there is no problem with the crane girder, the crane can be safely put into use.
