=====Tip Welding=====
Contact tips or formed contact parts produced by processes as described in chapter 3.1.2 [[Manufacturing Technologies for Contact Parts#Contact Tips|Contact Tips ]] are mainly attached by tip welding to their respective contact supports. In this process smaller contact parts such as Ag/C or Ag/W tips with good weldable backings are welded directly to the carrier parts. To improve the welding process and quality the bottom side of these tips may have serrations (Ag/C) or shaped projections (Ag/W). These welding aids can also be formed on the carrier parts. Larger contact tips usually have an additional brazing alloy layer bonded to the bottom weld surface.
Tip welding is also used for the attachment of weld buttons (see chapter 3.1.3). The welding is performed mostly semi or fully automated with the buttons oriented a specific way and fed into a welding station by suitably designed feeding mechanisms.
