Xiang Welding Industrial Co Ltd
G3Si1 can be used in tee welding of carbon steel and low alloy steel in the corresponding strength grade, which can be used in engineering machinery, ship, vehicle manufacturing, petrochemical and other industries. Characteristics: wire is 500MPa level carbon steel wire. It take C02 or gas shielded arc welding. The welding spatter is
small, and it has beautiful appearance, high cladding efficiency and small weld metal porosity sensibility. The welding technology of all positions is good.
Precautions: 1 . Clear rust, oil, water and other impurities on the weldments before welding. The size of the welding line energy will directly affect the mechanical properties of the weld. The size of the line energy depends on the important level of the structure. The more important the structure is, the smaller the line energy should be taken. Welding parameters are only provided for reference. The user should develop an appropriate production welding specifications according to the

Notes on usage:
1.E.S.O. (Electrode Stick Out) must be kept between 15-25mm.
2.Proper welding conditions must be adopted according to the purpose as the bead appearance and penetration are both varied widely.
3. Use 100% Co2 or Ar + Co2 gas mixture as shielding gas.
4. Control within the optimal range of welding conditions for this wire as possible.
