| INCREASE STAINLESS STEEL WELD PRODUCTIVITY USING 17 CLASS STAINLESS STEEL MMAW ELECTRODES |

What are 17 Class Electrodes? |
The flux coating of 17 class electrode is different from the flux coating of 16 class stainless steel electrodes. In 17 class stainless steel electrodes silica replaces part of the titania in the coating of 16 class leading to improved operational efficiencies. Some of the salient features of 17 class stainless steel electrodes are detailed below, |
- In horizontal fillet welding, the bead shape is totally flat to concave resulting in assured minimum 10% increase in weld length
- The controlled slow freezing characteristics of this class of electrodes improve handling when employing the dragging technique
- The spray type of arc during welding results in finely rippled weld beads
- Excellent in vertical up welding with little weaving
- Electrodes work in all position except vertical down

Betanox Plus range of Stainless Steel Electrodes |
Ador Welding Limited has been supplying the Betanox Plus range of stainless steel electrodes for the last several years. These electrodes conform to the 17 classification and have all the characteristics described above. In addition, the Betanox Plus range of electrodes has the following superior features, |
- The electrodes do not exhibit red hot tendency, enabling the electrodes to be used completely. Result is minimum stub loss and considerable savings since stainless steel electrodes are expensive
- The arc is smooth and spatter loss is negligible
- Weld bead slag is self peeling, so welder saves time on cleaning the weld bead
- Weld beads are smooth, shining and uniform with fine ripples
- Stainless steel electrodes generally require re drying before use to eliminate porosity. Betanox Plus electrodes can be supplied optionally as vacuum packed to eliminate re drying before use
- It is very welder friendly since arc striking and re striking is easy
- Electrodes are available for welding all grades of stainless steels e.g. Betanox 308 Plus is suitable for welding 304, 308 grades of stainless steels and so on

Suggested precautions for improved results when welding Stainless Steels |
- Store electrodes in dry place
- Re dry electrodes for best results
- Use electrodes well within the recommended currents
- Ensure good fit up on joints
- Hold short arc
- Adopt proper/ recommended welding sequence and
- Slag should be removed and weld cleaned only with stainless steel brush
