International Materials Reviews 61, 71–100. Burn-off is the change in length of the workpiece as its substance is turned into flash – material that escapes around the weld. We have Friction Welder, Linear Friction Welding, China Friction Welding Machines and so on. Friction Welding (FRW) is a solid state welding process which produces welds due to the compressive force contact of work pieces which are either rotating or moving relative to one another. Welding titanium alloys through linear friction welding is commonly used within the aerospace industry, titanium is favoured due to it’s high strength to weight ratio and durability. Solid state welding are those welding process in which no external heat is applied or no molten or plastic state involves. In fact, Alan Taub, the former LIFT chief technology officer and now senior technical adviser to LIFT, said the … rise to the diverse friction welding processes, which are described in the following subsections. Integrating rotational friction welding machines into your production network is a proven means of increasing your productivity.This requires open interfaces and intelligent control. Since there is no melting, solidification defects don’t occur in Linear Friction Welding, thus virtually eliminating gas porosity, segregation, or slag inclusions. In this type of welding, welding occurs due to external pressure applied into the solid state. Linear Friction Welding is a solid-state process in which one part moves in a linear motion at high speed and is pressed against another part held stationary. Another advantage is that in many instances quality of joint is better than that obtained using rotating technique. The basic steps explaining the friction welding process are shown in Fig.4.4.1.
