MAGNA Arc Welding

MAGNA

Arc Welding

Magna Welding Alloys provides you with: Great Versatility, Better Physical Properties and Greater Ease of Application.

The Magna difference is in the microstructure of the weld metal.

Ordinary welding wires are made to match a standard base metal analysis. Most base metals are rolled, forged, or heat-treated, which improves their physical properties. With ordinary electrodes, the melting and resolidification process changes the deposit structure completely from that of the base metal.

Magna alloys contain rare earth compounds, special alloying elements, deoxidizers and stabilizers. These compensate for the transformation of the electrode composition during the critical melting and resolidification phases.

Gas Welding Brazing & Soldering

Just as there is no universal medicine that will cure all ailments, some cast iron repairs lend themselves to gas welding better than arc welding. In other cases, arc welding is more practical than gas welding.

Types of applications where oxyacetylene welding is generally preferred:

  • Small parts, such as a broken lever.
  • Repairs such as a fracture where both parts to be joined are loose and free to move.
  • Welds where the weld metal must have the exact, or almost exact, same properties as the base material. For example, a glass mold where a weld with dissimilar coefficient of expansion and contraction could cause a spot or flaw in the glass.
  • In some machine applications where heat, corrosion, color or other reasons require that the weld metal have the same properties as the base metal. For example, valve ports in cylinder heads.

Most engineers would prefer to oxyacetylene weld any part where facilities are available and it is practical to preheat, especially on parts where the crack cannot be reached by an electrode but the iron must be melted in order to obtain access. For example a crack between valve ports. Here usually only the top of the crack is reachable. It is therefore necessary to melt down into the crack in order to weld the complete crack. In such case, the oxyacetylene torch is naturally used.

Welding Aid Products

Maintenance welding requires a combination of skill, ingenuity, confidence, imagination and determination, all intermingled with scientific principles. Welding, of course, involves the four sciences of chemistry, metallurgy, physics and engineering. One without the others will fail. However, proper proportions of all will result in greater savings through maintenance welding.

One of the great difficulties in maintenance welding is the fact that the know-how steps often have to be carried out by the welder himself. And it is for this reason that Magna has researched and developed a number of Welding Aid Products exclusively for maintenance welders.
