Description:
CHW-50CSM is a low alloy steel type wire covered with copper. It is able to
prevent gas porosity and slag inclusion producing due to the deoxidation
depending on Mn and Si in the wire jointly. In this way, the crack
resistance of weld metal can be developed and satisfactory mechanical properties
can be obtained.
|
Applications:
Suitable for CO2 gas shield welding of
mild steels and low alloy steels structures, such as ship, containers, vehicles
and pressure vessels etc.
