This detailed product description refers to the high-quality SG2 Ti vb type welding wire offered by Wieländer+Schill, which has been specially developed for MAG (Metal Active Gas) welding processes. The product is an ideal choice for welding general unalloyed and low-alloyed steels, especially for materials with special surface treatments.
A SG2 Ti vb welding wire is a low-alloyed steel wire supplied with a bronze coating, whose diameter is precisely 0.8 mm. The bronze coating provides a critical advantage: provides further protection against corrosion, thereby increasing the durability and quality of the weld seam.
This wire is particularly suitable for applications where the surfaces to be welded have been pre-treated, for example:
Overlapping of manufacturing coatings (primers).
Welding through zinc protective layers.
Welding parts with rust or surface contamination.
The wire performs excellently during MAG welding processes, ensuring a stable arc and excellent bead formation. The weld seam resists aging, which guarantees long-term reliability. The wire can be used over a wide temperature range, between operating temperatures of -10 °C and 450 °C while maintaining its mechanical properties.
The product It is wound on a K300 type spool , representing a net weight of 15 kg, ideal for large volume, continuous welding tasks.
The table below summarizes the most important mechanical and physical characteristics of the welding wire that guarantee professional use:

A characteristic of the SG2 Ti gas metal arc welding wire is the fine bronze coating. This coating not only enhances corrosion protection but also contributes to the stability of the welding process. Bronze aids in the uniform feeding of the wire and reduces spatter, resulting in a cleaner, more efficient weld, especially during automated or semi-automatic procedures.
This welding material is ideal for the following industrial segments:
Automotive and Body Repair: Excellent for welding primed or galvanized surfaces where the weld seam must meet strict quality requirements.
General Mechanical Engineering: Manufacturing of non-alloy structural steels, boilers, and pressure vessels, where the lower limit of -10°C can be important for operation in cold environments.
Pre/Post-Weld Surface Treatment: The wire is specifically suitable for jobs where further surface treatment (e.g., painting) follows the welding, as the weld seam's aging resistance ensures long-term integrity.
For the efficient and safe use of K300 basket spools, the following adapters are recommended (available for separate purchase):
Adapter for K300 bobbin spool (1 piece):
Part number: 307002
Features: Single-piece adapter equipped with eight arms and two locking levers.
Adapter for K300 bobbin spool (2 pieces):
Part number: 307003
Features: Two-piece adapter with quick lock for K300 bobbin spools.
These adapters ensure the proper fixing and feeding of 15 kg spools in the welding equipment, maximizing productivity.
A Wieländer+Schill SG2 Ti vb 0.8 mm welding wire A reliable, high-performance consumable that offers outstanding corrosion protection and excellent welding properties thanks to its bronze coating, especially for low-alloy steels, particularly surface-treated or slightly rusted base materials. The K300, 15 kg packaging provides an economical solution for professional workshops.
