Bevel processing on 2/6 mm×2 500 mm×6 900 mm titanium/steel clad plate by milling machine, edge planing machine and other traditional methods cannot meet the specification requirement “straight edge, groove width 5 mm, edge UT conform to ASTM A578-07 Class C”. So the reason of clad plate lamination by machining was analyzed，and the traditional methods were instead by laser cutting and circular saw cutting. By optimizing the laser power, peak power, pulse frequency, auxiliary gas, speed of feed, rotational speed of circular saw and other parameters, the problems of edge lamination, titanium layer separation and so on which discovered in bevel processing on titanium/steel clad plate were solved. The products can meet the customer requirements through UT inspection.
