Our vacuum boxes are used to check the tightness of welds. Unlike their competitors our boxes are lighter, they are also designed in such a way that they can be configured to test fillet or groove weld seams.

It is used mainly to:

• Leak test of welding seams 
• Leak test of welding grooves
• Leak test of welding seams or grooves at its pass throught a web, girder or bracket

In addition, by using two of them you can check the welding under the scallop of the webs or brackets.

If our standard models sizes do not match your requirements we can manufacture them to your prefered size.
