technologies (welding, brazing, soldering) Brazing is a method of joining two metal work pieces by means of a filler material at a temperature above its melting point but below the melting point of either of the materials being joined. Flow of the molten filler material into the gap between the work pieces is driven by the capillary force. The filler material cools down and solidifies forming a str… text/html 2008-06-26T10:07:02-04:00 http://www.substech.com/dokuwiki/doku.php?id=laser_welding_lw&rev=1214489222&do=diff1214489222 Discuss the article and ask questions in our Materials Forum to Metals to Metal joining technologies (welding, brazing, soldering) Laser Welding (LW) is the welding process, in which heat is generated by a high energy laser beam targeted on the work piece. The laser beam heats and melts the work pieces edges, forming a joint. Energy of narrow laser beam is highly concentrated: 108-1011 W/in2 (108-1010 W/cm2), therefore diminutive weld pool forms very fast (for about 10-6 sec.).
