1. Introduction
After finished the H-beam assembling
process, H-beam automatic SAW welding is required. It has several structural
styles: LHA gantry type, LHT double cantilever type and LHC cantilever type. It
adopts A.C. variable frequency control to realize back and forth welding. It
has stable and reliable working and simple and convenient operation. Special
designed arc-guiding rack can satisfy the welding requirements of small H-beam
and star/cross beam.
