2X SAW 4 torch membrane panel welding machine | 1X MIG/MAG 12 torch membrane panel welding machine | |
Weld penetration | Deep, 3 - 5mm | Shallow, 1 - 1.5mm |
PPE |
No light pollution operator assumes basic PPE |
Intense light pollution Welding mask Protective clothing |
Weld quality |
Good weld presentation Minimal rework |
Average weld presentation, often porosity, spatter, undercut Requires rework |
Welding consumables | Flux, can be recycled | Inert gas, gas not recycled |
Left over | Welding slag | None, balance gas evaporates |
Process | One side welded during a single pass | Both top and bottom side welded during a single pass |
Productivity | 0.8 - 1.5m/min | 0.5 - 0.7m/min |
Manpower | Easy to operate, one operator required for 4 torches | Requires experienced welder |
Welding dies | Minimal amount of welding dies, dies replaced when fin bar size or centering height changes |
High volume of welding dies. Different tube diameter or different fin bar size requires change of dies. Large effort in replacing dies. |
Cost of welding dies | Low cost, estimated at USD500.00 | High cost, estimated at USD20,000.00 |
Acceptance | Accepted by all | Used only with allowed fabrication process, typically in small/low pressure applications within limited regions in the world |
