Most grades of steel used in rebar steel cannot accept welding, which could be useful to bind several pieces of rebar together. Special grades of rebar-steel' steel and welding rods make the welding by expert welders achievable.

Bending and welding rebar-steel into shapes that are suitable for fixing into the concrete is normally performed by specialist reinforcement fabricators. Little reinforcement is cut and bent on-site. Even though the bending and cutting of rebar-steel appears somewhat straightforward, the specialist reinforcement creator is well equipped to do so in an accurately. By working within a defined set of quality management criteria, the fabricator provides an the link in the rebar-steel supply chain. The accuracy of cutting and bending operations is vital to ensure that they fit properlyat the site, as well as to keep required lap lengths, the anchorage lengths and cover.

Tungsten inert-gas (TIG) welding, the third of the three major types(the others being Torch and MIG) is by far the cleanest and has the most precision. It is also the most expensive. In one aspect it is very like MIG welding where an arc is struck between a non consumable tungsten electrode and the working piece, shielded by inert gasses like argon, helium, and carbon dioxide to protect the molten metal from being contaminated. However in this case the tungsten electrode is not exhausted because of its very high temperature of melting. Then filler material is supplied separately as wire or rod. TIG welding works well with thin sheet and can be used manually, and is also easily automated. Both the deposition and penetration rates will be a lot less than those of MIG welding, but the welds' precision control is easier.
