1) Function: BOX Beam SAW Welding Machine performs Twin Arc or even Triple Arc submerged arc welding on the assembled, tack welded, back welded, and electroslag welded BOX Beam flowing in the BOX Beam Production Line;
2) Classification: Based on structure of mechanical main frame, there are 2 types of BOX Beam SAW Welding Machine: LHE12 Gantry type and LHC12 Cantilever type;
3) Both types work in the same working mode: BOX Beam is put stationary on conveyor of the BOX Beam SAW Welding Machine, and the gantry frame or cantilever trolley moves in adjustable welding speed, performing Twin Arc or Triple Arc submerged arc welding at the same time;
4) Quality Control: During working of the BOX Beam SAW Welding Machine, welding torch is controlled with air cylinder drive mechanical style welding seam tracing unit, guaranteeing welding quality and productivity of the BOX Beam Production Line;
5) Working Nature: We can see that gantry type BOX Beam SAW Welding Machine has very similar machine structure and working principle as H Beam Gantry Welding Machine; And cantilever type BOX Beam SAW Welding Machine can be replaced as column structure H Beam Welding Machine which are deployed 4 sets in a group in automatic H Beam Production Line;
6) Quantity: In BOX Beam Production Line, there are 2 sets of either LHE gantry style or LHC cantilever structure BOX Beam SAW Welding Machine.
