CORBY STEEL IS A WORK OF ART

Corby’s Electric Welded Stretch Reducing (EWSR) Mill 2 is to benefit from a brand new tube welder, finally replacing one of only four remaining valve welders left in the world. EWSR and Central finishing Operations Manager, Adrian Price said: “It is fantastic to see nearly £1m of investment coming to the line, which will bring higher line speeds, more consistent weld quality and vastly improved reliability. What’s more, the new welder is designed with a low voltage supply meaning less

dependence on High Voltage (HV) permitry for maintenance work. The scheme is a key part of the Corby Improvement Plan.” “As time has gone on, the line has unsurprisingly become increasingly unreliable, and we’ve had stoppages waiting for spares to be manufactured. The fact that our engineers have

kept the line going so long after the technology has effectively become obsolete, is huge testament to their skills, determination and resourcefulness.” The original HF weld was made by “Electro-heating” using the latest valve technology in 1980. In the late 90’s Corby Works committed itself to replacing all of the old valve welders with IGBT transistor technology. The 6” EW Mill was first, then CFM 1 & 2. The programme was however stopped, leaving EWSR 1 & 2 still with the old valve HF Welders.

Adrian explained: “As time has passed, the valve HF Welder manufacturers, valve makers and many of the component makers have either gone out of business or made components obsolete. The skills to maintain the passive component welders has diminished to such a state that our own engineers are arguably the world experts. “Now we can look forward to 21st century joining technology, with the project planned to start during the summer shutdown in July / August.”
