Production Engineering distributes individually upset-forged
and heat-treated seam welding wheels, tube mill electrodes,
plate and bar. Most products are available from inventory,
or can be custom made to meet your specific needs.
There is a direct relationship between production down-time
and the method of manufacture of seam welding wheels (resistance
welding electrodes). Individually upset-forged welding wheels
outperform cast wheels every time, making them the clear
choice for extending electrode life. Many RWMA suppliers
do not understand the importance of, and do not supply, individually
forged wheels.
Why upset-forged seam welding wheels perform better, last
longer...
- Individually upset-forged seam welding wheels increase
production up-time and enhance weld performance because
of their fine equiaxed grain microstructure.
- Fine radial grain flow, the essential property for minimizing
premature edge deformation, can only be produced by the
upset forging process. Each wheel must be individually
forged and heat treated to develop this advantageous microstructure.
- Cast wheels, produced without forging, have large columnar
grain structures that contribute to edge chipping and flaking,
unreliable performance and higher production costs.
How to tell them apart...
- Forged and cast wheels look alike and have similar hardness
and electrical conductivity properties. On the surface
it's hard to tell them apart. But, when the surfaces of
both wheels are chemically etched, the difference in the
grain structure is revealed.
