Beam Welding Line Machine; Boom welding machine is generally used for welding of mobile crane booms. Boom is fixed by hydraulic clamps, which enable easy holding of the booms on the machine. This prevents boom from twisting or bending during welding. It can be controlled by plc screen on the machine. The machine has a horizontal slide system and the hydraulic jaws integrated to this system ensure that the workpieces remain vibration-free and stable. In this way, the Beam Welding Machine moves and welds to the sections chosen by operator
