Application of laser seam tracking in friction stir welding systems
Friction stir welding has been widely used joining of aluminium alloy. However, the shiny surface of Al and its very tight seam bring the challenge to the FSW system manufacturer. laser based seam tracking system uses the principle of triangular to find the position of seam relative to the fsw Read more…

Flux assisted TIG welding(A-TIG)
The A-TIG welding process involves a method of increasing the penetration capability of the arc in TIG welding.[1]This is achieved through the application of a thin coating of activating flux material onto the joint surface prior to welding. The effect of flux is believed to constrict the arc which increases Read more…
