Engineering Weld Services

Not all welds are equal, and in maintenance, the wrong one tends to fail exactly when a plant can least afford it — usually under load, under pressure, and without much warning beforehand.

For over 25 years, Permaweld has provided maintenance welding services for engineering components across heavy industry, using alloys engineered specifically for repair and rebuild — not new production, because the demands on a repaired part are fundamentally different from the demands on a freshly manufactured one.

Standard welding electrodes assume the electrode material and base material are the same — an assumption that breaks down in maintenance welding. Contamination from sulphur, phosphorus, and carbon in the electrode creates porosity and cracking in the base material; phosphorus specifically causes brittleness at low arc temperatures, and oxygen contamination reduces impact toughness and tensile strength. Standard electrodes also need pre-heating because they absorb moisture from the atmosphere, and their coating has a short shelf life that can peel during storage, degrading weld properties before the electrode is even used.

Maintenance work also means welding across very different base materials in the same plant — cast iron, cast steel, gear teeth, damaged chassis — which normally means stocking a wide range of electrodes. MAGNA's maintenance-specific alloys are formulated for the higher strength that stressed, strained base material demands, giving a longer and more reliable repair life across all of it, so a plant doesn't need a different specialist alloy on hand for every type of component it might need to repair.
