What is solidox welding?

Solidox welding is a type of gas welding that uses a mixture of oxygen and an oxidizing agent, such as calcium permanganate, to generate heat for welding. The oxidizing agent is usually contained in a stick called a "solidox rod" that is inserted into the welding torch. The solidox rod is ignited by the high temperature generated by the welding torch and then produces a hot, oxygen-rich flame that melts the workpiece material.

Solidox welding was developed in the early 1900s and was used extensively during World War II for repairing ships and tanks. It is still commonly used today for welding and cutting ferrous and non-ferrous materials in industries such as automotive, aerospace, and construction.

One of the advantages of solidox welding is that it provides a high heat output, which makes it suitable for welding thick materials. It is also relatively simple and easy to operate, requiring only a welding torch, solidox rods, and a source of oxygen. However, it produces a lot of heat and can be dangerous if proper safety precautions are not taken. Additionally, solidox rods can be expensive and may require special handling and storage.
