Welding rods are fillers that add to the molten pool of metal. They are usually stronger than the metals being fused. In arc welding, they have a coating that burns and creates a shield around the puddle.
welding rods are used for weld two pieces of metal together, or to cut metal if you have big enough rods and enough amps.
depending on the diameter of the rod, generally there will be approx. 26 (+/- 1) welding rods per pound.

why oxyacetylene filler rods cannot be used for gas tungusten ar welding
Different material welds differently depending on polarity. There are also different types of welding rods, so polarity must be tested.
Thorium welding rods offer several advantages over other types of welding rods. They provide better arc stability, higher current-carrying capacity, and improved heat resistance. Additionally, thorium rods have a longer lifespan and produce less spatter during welding, resulting in a cleaner and more efficient welding process.

Welding with cast iron welding rods
Yes, welding rods are generally magnetic because they often contain iron and steel elements. However, the magnetic properties may vary depending on the specific composition and coating of the welding rod.
The difference in the ac/ dc , or polarity of welding rods is in the makeup of the flux coating , or the alloy of the metal, and in the case of SMAW ( Shielded metal arc welding ) rods , which have a flux coating, are usually marked on the base of the rod.

Welding rods can be magnetic or non-magnetic, depending on the material they are made from. Most steel welding rods, particularly those made from ferrous metals, are magnetic due to their iron content. However, certain welding rods made from non-ferrous materials, such as aluminum or stainless steel, may exhibit little to no magnetism. The specific composition of the rod determines its magnetic properties.

The new principal inside welding machines is based on metal-arc welding, whereas the older welding machines used electromagnetic winding to increase the current in welding rods.
all stainless steal is, is painted harden steel with a special paint. They usually do not weld stainless steal they are all shaped when forgedStainless steel is NOT painted steel, it is "stainless" because the surface alloy contains significant levels of chromium which resists corrosion. Standard welding can destroy this chrome-steel alloy surface, leaving it open to corrosion at the weld, however there are welding methods that work with stainless steel, like electrical spot welding.
The number of welding rods in a 5 kg box depends on the weight of each individual rod. For example, if each rod weighs approximately 0.5 kg, there would be about 10 rods in the box. If the rods are lighter, say 0.3 kg each, there would be around 16-17 rods. To get an accurate count, you need to know the weight of the specific rods included.
