Features and applications:

W49 – VD is a copper-plated welding wire, used with CO2 or Ar-CO2 shielding gas. It is suitable for semi-automatic or automatic (robotic) welding machines. The weld has deep penetration, high ductility, and impact toughness at -30°C.
Suitable for welding low-carbon and low-alloy steels with loads from 490 to 550 MPa, such as in the automotive, vehicle, machinery, shipbuilding, and pressure vessel industries.
Higher welding productivity than using welding rods or TIG welding. Welding is possible in all positions.

Instructions for use:

Clean off oil, grease, dust, and dirt before welding.
The weld edges are processed according to specifications.
Choose the appropriate welding current and voltage to avoid defects.
Maintain a distance of 5-15 mm between the workpiece and the gas nozzle.
Welding gases must meet standards, free from water vapor, oxygen, etc.
Ventilate the welding chamber to prevent suffocation from CO2 _gas .
Shield the welding area to prevent oxygen _from reaching the weld pool and causing sparks.
