These little boxes connect to a suction tank with a hose fill up with a soapy solution and adhere over the top of a weld. When pressurized, our technician is able to evaluate whether or not air is coming through the weld, by watching the bubbles in the soapy water. If they are stationary, there are no leaks in the weld, but if the bubbles are moving, growing or expanding, there is a crack where air is entering the soapy solution.
If there is a crack or fracture, our technician will be able to locate it and recommend your next action steps to get it repaired, and possible safety measures that will need to be taken, until the weld is repaired.
Keep your operation running smoothly, let us come and check it out.
