There are hundreds of small diameter pipes welded in close rows on the header, and the spacing is narrow. Usually, only half a circle of magnetic particle and penetration detection can be done in the outermost pipe row.FGI pen array probe can effectively cover the fillet weld of the small diameter joint box tube seat without grinding and cleaning the weld, which can not only quickly detect the length of the surface crack of the fillet weld, but also accurately measure the crack depth, crack branch trend and other permanent information, providing a reliable basis for subsequent maintenance.
