Hello!
It was a tough week for us before we come up with the good result after several test trials (we almost scrapped 50tons of pipe).
To share, we just modify our welding conditions from the previous qualified one.
Previous Set-up:
> Outside SAW Parameters: DC- 850Amps/28V, AC-500Amps./30V, Welding speed: 1.8meters/min.
New Set-up:
> Outside SAW Parameters: DC- 900Amps/31V, AC-500Amps./33V, Welding speed: 2.1meters/min
We are in normal production right now.
Thank you Sir/s John, Brent, Lawrence, Tim, Phil & sir Gerald for the inputs.
Have a great day!
