Features and Applications
|
|
|
In addition to appropriate amount of Si, Mn, the addition of Ti to SJ-58 woule refine the globular grain of weld and help stabilize electric arc; In comparison, spark spatters and smog is reduced by a large margin.
Not only does Ti contribute to the refinement of weld bead grain, it also increases the strength of weld bead and impact value. Under the operating condition of high current, the wire's superiority is best shown and suitable for thick plate butt joint welding, fillet welding and horizontal welding.

Points for Attention
|
|
|
¡¤Ensure that the purity of shielding gas and the purity of CO2 must be above 99.98%.
¡¤Keep the shielding gas flow at 20-25L/min.
¡¤Keep the electrode extension between 15-25mm.
¡¤ Rid the welded part of rusty layer, damp, oil stain and dust, etc.
¡¤Always keep torch nozzle clean and TIP in good condition.
¡¤Use the wire under the best possible conditions.
