Model: Ferrule Stud

A ferrule (ceramic welding auxiliary material) is required for stud welding.
The ferrule blocks the air during arc generation, prevents reaction between the weld metal and air, and slows down the arc heat cooling speed.
It also acts as a collar mold around the stud that traps the weld metal inside the ferrule.
Ferrule Stud
There are various sizes of headed studs, odd-shaped studs, and threaded studs, and various types suitable for welding positions.

Model: Heterogeneous Stud

Heterogeneous studs are widely used as joint reinforcing bars for expansion joints of road bridges, pillars of steel slab bridges, building foundation pile head joints, earthquake resistant walls, pillar anchor plates and others.

Steel bars for reinforced concrete SD 295 A, B and SD 345 prescribed in JIS G 3112 have no carbon, hence greatly affect the weldability. On the contrary, if there is any amount of carbon in steel bars, this amount will be very high and it cannot be an appropriate welding material.
We have made an agreement with steel bar manufacturers on the many specifications like: chemical composition and mechanical properties of steel bars in order to achieve good welding ability and deforming studs.

Application:

JFE-DS 400 D (KDS 400 D): Rebar of bridge-oriented steel expansion joint such as anchor bar, high wall column, median strip (D 25 only)
