The machine is equipped with four quadrupole-electrode submerged-arc welding heads, and moves by a central control system; the welding carriage automatically senses and tracks the welded joint to execute one-sided automatic welding of heavy plates having a maximum of four weld seams. Furthermore, with regard to crater cracking in welded parts, the adoption of a practical crack-prevention method and the application of this newly developed welding machine, will have a great effect on labour saving in plate-joining work.
