H Beam Submerged Arc Welding machine is the 2nd set of core H Beam production equipment, and also the most important machine of H Beam production. It determines directly quality of welding H Beam produced.
As its name suggests, this H Beam Welding Machine is used for welding the assembled and tack-welded H Beam with submerged arc welding. There are 4 seams need to be welded for each piece of H Beam (the top and bottom juncture between web and flanges of left and right side).
Depending frame structure of H Beam Submerged Arc Welding Equipment, it has models of:
1) Gantry type (LHA- series) --- Used as separate H Beam Weld Machine, not available for automatic H Beam production line;
2) Column type (LHC- series) --- Majority used in automatic H Beam production line, and can also work individually. In other words, LHC is the only H Beam Welding Equipment that can be used in automatic H Beam production line;
3) T type (LHT- series) --- Same as LHA, Used as separate H Beam SAW Machine, not available for automatic H Beam production line
For LHC-series and LHT-series, the standard H Beam web width is up to 1500mm ~ 2000m, which can be designated by customer.
For LHA- series, based on its control manner and rail span, there are several options of sub-classification to choose from (detail information please check introduction of each model):
