Description:
CHE58-1 is an outstanding quality electrode covered with low hydrogen potassium type coating
containing iron powder for welding high tensile steel. The special technology is introduced from
a famous company in Europe. It's nominal welding efficiency is about 11O%.
DC is recommended to all
position welding and it demonstrates very satisfactory performances, although both
AC an DC could be used. The weld metal shows a low temperature toughness and high crack resistance.
The groove of workpieces have to be away impurities and It is necessary to bake the electrodes at
the temperature of 400oC for 1 - 2 hours before welding.
|
Applications:
Suitable for welding of ship steels and of important
structures made of low alloy steels with same grades strength, such as boilers,
bridge ship, sky-scrapers, and offshore drilling platforms etc.
