CN104209625A - Q460 steel thick plate welding process

The invention discloses a Q460 steel thick plate welding process, which comprises the following steps that the top end and the bottom end of the side surface of a Q460 steel workpiece to be welded are cut, so that two workpieces are in butt joint for forming two asymmetric double-V-shaped grooves; the ground workpieces are subjected to pairing welding; welding seam regions are preheated; the China's Q345D low alloy steel plate Prices on June 11 The price of Q345D low alloy steel plate in the Chinese market is rising. The price of 10mm Q345D low alloy steel plate is 661.54 usd/ton, 1.54 usd/ton higher than that of yesterday; The price of 22-25mm Q345D steel plate is 633.85 usd/ton, 1.54 usd/ton higher than that of yesterday. And the price of 30mm Q345D low alloy steel plate is 633.85 usd/ton, 1.54 usd/ton higher than that of yesterday.
