Stadler to deliver<br />
32 train units to Finland<br />
Switzerland’s leading rolling stock manufacturer<br />
Stadler Bussnang AG will be delivering<br />
32 new train units for use in local<br />
commuter traffi c for the Greater Helsinki<br />
area. Because the quality of welds on the<br />
aluminium structures of the rolling stock<br />
is to be uncompromising, Stadler uses<br />
<strong>Kemppi</strong> Pro and Pro Evolution machines<br />
on the most demanding welding jobs.<br />
The ordered Flirt trains are approximately<br />
75 metres in length and have a passenger<br />
capacity of approximately 250 for each<br />
unit. By Finnish standards, the train order<br />
is a major one, as the ordered units will<br />
be carrying 40% of the Greater Helsinki<br />
area’s rail traffi c.<br />
Aluminium has for years held a dominating<br />
position in vehicle manufacturing, due to its low<br />
weight and excellent mechanical properties. Stadler has<br />
used aluminium in its products for decades.<br />
Head of aluminium structures Bernhard Eisenegger,<br />
who also has years of experience in working with aluminium,<br />
will be celebrating his 30-year career with the<br />
company next year.<br />
“At fi rst we manufactured products primarily for the<br />
Swiss market, but now our rolling stock is delivered all<br />
over the world,” explains Eisenegger.<br />
Stadler relies on <strong>Kemppi</strong> machines for aluminium welding.<br />
The fi rst <strong>Kemppi</strong> machines were purchased by the<br />
company nearly 30 years ago - today, the aluminium<br />
section has a total of 50 <strong>Kemppi</strong> Pro and Pro Evolution<br />
welding machines.<br />
“We’ve been especially satisfi ed with the reliability and<br />
adaptability of the machines, and the quality of welds,”<br />
says Eisenegger. “For our most demanding jobs, we use<br />
the <strong>Kemppi</strong> Pro Evolution 4200 MIG machine with the<br />
MXE control panel.<br />
The <strong>Kemppi</strong> Pro Evolution machines are equipped with<br />
8-metre push-pull guns and the connected ProSync<br />
synchronization unit. This ensures a problem-free and<br />
steady wire feed on long welds.<br />
These guns are water-cooled and the ProCool 20 water-<br />
cooling unit ensures that the gun stays suffi ciently cool<br />
under demanding welding conditions.<br />
“Insuffi cient gun cooling results in welding errors, such<br />
as porous weld seams, and can cause problems in the<br />
wire feed,” reminds Eisenegger. n
