| Step 1: Clean area to be welded. |
![]() Clean area to be welded with wire brush. |
![]() Wipe area with a saturated cloth - such as EZ Wipes® by Aquasol. Wait approximately two minutes for cleaning agents to evaporate. |
![]() EZ Wipes® feature a two-sided cleaning fabric, an abrasive side to loosen dried on surface contaminants, and a smooth side to reveal a cleaner, polished surface. |
| Step 2: Construct Dam. |
![]() Trace the pipe's inner diameter on the paper by pressing against the pipe to create an impression of the pipe. |
![]() Cut Aquasol® Paper into a circle with a diameter about 1.3 times the inner diameter of the pipe. |
![]() Slit approximately 1" to 2" segments perpendicular to impression on paper. Do not exceed inner diameter circle. |
| Step 3: Insert Dam and tape in place. |
![]() Insert dam 6-8" from root gap with the lip toward the weld preparation. |
Tape dam in place. |
Repeat Step 2. Insert and tape dam on opposite pipe. |
| Step 4: Introduce gas and weld. |
Cover root gap with EZ Zone™ Tape, a contaminant-free gas retaining tape. |
Insert purge gas needle into root gap. Ensure connection to gas line. |
![]() Introduce noble gas and start welding. |
| Step 5: Dissolve Aquasol® Water Soluble Purge Dam. |
![]() Simulation of hydro-test (flushing line). |
