Babbitt lined Bearings used in Ball Mill etc. tend to wear in service and require rebuilding.

Worn Bearings can be recoated by

  • ARCSPRAY PROCESS using ARCWEL BABBITT 90 SN wire
  • This product can also be applied by the GTAW Process
  • Available in size 2 and 3. mm supplied on 10 kg spools

Francis, Kaplan & Pelton Turbines are used
in Hydropower and commonly made from
AISI 410,420, 430 Steels.

The blades are subject to wear by cavitation

The following products have been used
successfully for build up and repair

SMAW PROCESS ARCWEL 240-SMAW

GTAW PROCESS ARCWEL 240-GTAW

Special high cavitation resistant electrodes
and wires are available on request..

Surface Protection of Boiler Tubes

Waterwall , superheater, economizer& evaporator
tubes in coal fired power stations are subject
to high temperature corrosion.

ARCWEL offers the following products for protection
