The four column hydraulic press adopts an integral welded open structure which is conducive to the rigidity of walking, and it also helps to increase its working space. But the core is still the quality of the welding work. It is not only necessary to use precise methods and techniques to complete the welding. The quality inspection of the welds of the four-column hydraulic press should not be underestimated.

Compared with other construction methods, the four column hydraulic machine body can be adsorbed on the steel, and it also has a convenient working space, thereby increasing the scope of use.

Accurately inspect the welding quality of the four-column hydraulic press. The inspection standards for the welding quality of the four-column hydraulic press are the same as others. The most important thing is whether there are any safety hazards around the weld, such as cracks, inclusions, pores, splashes, etc. Secondly, the weld is not regular. Are there any protrusions on the inside or outside of the workbench? If necessary, the welding seam of a four-column hydraulic press can be used to complete radiographic inspection or ultrasonic inspection to ensure the stability of welding inspection. Once it is found that the welding is not up to standard, it is necessary to complete the welding repair in time, and also need to pay attention to the frequency.
