Welding steel

Steel is perhaps the most common type of metal used for welding. If you get started with welding a bicycle rack, a fence around your lawn or a frame for industrial furniture, the use of steel is a logical choice. The material is strong, easy to machine and has good weldability. How to work steel in the best way and what preparations you have to make before you work with the welding torch, I tell you in this article.

Examples

Examples of steel

Steel structures can no longer be ignored from our street scene. The very strong material is used, among other things, to make bridges, train tracks, buildings and tools. Steel is also one of the most used metals for sheet metal working. For the do-it-yourselfer, steel is a well-processed material for all kinds of constructions or repairs. From decorative workpieces such as weather vanes or garden fences, to furniture or a complete framework for a conservatory. In short, the possibilities with steel are endless.

What do you need?

What do you need to weld steel?

Due to the large variation in composition, not all types of steel can be hoped for. Stainless steel, like steel, is a ferrous metal, but the 2 materials have their own unique properties and therefore specific applications. In this article we mean with steel the material that mainly consists of iron and carbon. Which welding technique you use to weld steel is entirely up to you. Both with electrode welding, TIG welding and MIG / MAG welding you make solid welds. For welding of steel you do not need alternating current, but direct current. As far as the additive material is concerned: depending on the type of steel you are working on, there are all kinds of electrodes, welding rods and welding wires to choose from.

Tips

Tips for steel welding
  • Consider the thickness of the material when welding steel. Based on this you determine the height of the amperage. Because the thicker the material, the higher the current must be.
  • When determining the power supply, follow the following rule: for a 1 millimeter plate you need approximately 40 amps, for 2 millimeters 80 amps, etc. The welding consumables that you choose also depend on the plate thickness. A thick steel plate requires filler material with a higher diameter than thin aluminum.
  • Many different types of additive are available for welding steel, depending on your planned application. The composition of the welding rods, electrodes or the welding wire must match the type of steel that you are going to process.
  • You keep your steel construction nice and rust-free by finishing it well.
