Here in Michigan we legalized Marijuana recently. My customer previously was growing Marijuana for medical use and now he is expanding his operation for recreational use. There is currently a lot of profit in growing Marijuana. Somehow they wound up with a ten foot restaurant quality 304 stainless sink that was too long to get down the stairs to the nursery, so I cut it in half and welded it back together once it was moved back to basement.
1. Ten foot sink

The first step was to fabricate an Aluminum back up bar to trap the Argon and to minimize oxidation (sugaring) on back side of the weld joint. The next three pictures show clamping pieces of Aluminum angle to the bottom surface at the rear of the sink and tack welding it together.
2. Back up on rear of sink 1

3. Back up on rear of sink 2

4. Back up on rear of sink 3

The next pictures show clamping pieces of Aluminum angle to the bottom surface at the front of the sink and tack welding it together. I turned a bar of aluminum to fit into the round edge of the sink.
5. Back up on front of sink
