Gantry welding is a kind of welding equipment for H-steel manufacturing and processing. Because of its shape like a door, it is called gantry welding, also known as H-beam welding or steel gantry welding. Generally welded in the steel structure plant .The gantry-type H-beam welding machine is developed by our company based on special requirement of fillet welding in the down hand and years of experience and technique in welding equipment.

There LHA gantry type, LHC cantilever type automatic welding machine and LHT double column-beam automatic welding machine.
It adopts A.C.inverter control, with functions of stable running and fast traveling speed; The seam-tracking arc-guide mechanism is three-spindle system to guarantee the alignment without aberrancy; The main frame and welding machine are intergrated control, with flux auto-recovering system and it is easy to operate with high efficiency.
LHT double column-beam automatic welding machine can weld two pieces of beam at the same time, and the web height of beam is not limited by main machine.
