LHC Column Type H Beam Submerged Arc Welding Machine

1.     Application Site of LHC Column H Beam Welding Machine:

1)      The first photo denotes the typical application site of LHC model Column I Beam Submerged Arc Welding Machine: This model is basically for being applied in automatic H Beam Production Line;

2)      As explained in the product category of the SAW I Beam Welding Equipment, although in theory LHC can be used as individual machine, in actual practice this is very rare the case: (Fig.1) 

2.     The Similarities and Differences between Column type LHC and Gantry type LHA H Beam Gantry Welding Machine:

Both being applied as dedicated H Beam Welding Machine for welding H Beam production, there exist Common Point and Difference between Gantry type (LHAZ model, LHAC model) and (LHC model) Column I Beam Welding Equipment:

1)      Common Point between LHA and LHC Column I Beam SAW Machine:

a)       Welding Style of the SAW H Beam Welding Machine:

i.           Both LHC and LHA H Beam Gantry Welding Machine perform SAW on H Beam in the form of machine body travelling along the rail, and the workpiece H Beam being kept fixed during welding process: (Fig.2) 

ii.           Both the two I Beam Welding Equipment weld the H Beam in the position of 45° fillet welding, as shown in the above sketch;

b)      Outsourced Units in SAW H Beam Welding Machine:

Including SAW power supply, wire feeder, flux recovery, and arc tracing unit are exactly the same type and specification between LHA and LHC Column H Beam Welding Machine: (Fig.3) 

c)       SAW Welding Process Control in SAW H Beam Welding Machine:

Including parameters (Welding current, welding voltage, welding velocity), are the same for same specification of H Beam in LHA and Column H Beam Welding Machine;

d)      For this reason, operators who work on the LHC model Column I Beam SAW Machine can shift his duty to work on gantry type LHA H Beam Gantry Welding Machine without any problem;

e)      For producing welding H Beam, both kinds of SAW H Beam Welding Machine need to work together with the previous step of the H Beam Assembly machine, and next step of H Beam Straightening machine. And the Matching Assembly and Straightening machines are the same as well for LHA and LHC I Beam SAW Machine;

2)      Difference between LHC and LHA H Beam Gantry Welding Machine:

a)       Structure and Model of the H Beam Welding Machine:

i.           The half open column style of machine body (open structure) allows for free extension of H Beam along the rail, so there is no model variation in the LHC automatic Column I Beam Submerged Arc Welding Machine ---only one LHC to accomplish “One size fitting for all” of welding H Beam: (Fig.4) 

ii.           Comparatively, due to the enclosed frame in LHA H Beam Gantry Welding Machine, there are series of models (LHA4Z, LHA5Z, LHA55Z, LHA4C, LHA5C) to cater for varying sizes of H Beam;

b)      Welding Station Quantity: One welding station and one rail for one set of LHC Column I Beam Welding Equipment, compared with two welding stations in the case of LHA H Beam Gantry Welding Machine;

c)       Hence, quantity of the above mentioned outsourced units for one set of machine is different: Two sets of each kind for LHA gantry H Beam Welding Machine, and one set of each kind for LHC Column I Beam SAW Machine;

d)      Operating Position in SAW H Beam Welding Machine:

i.           For Column style LHC I Beam SAW Machine, operator stands on the moving column and trolley, and need not to walk: (Fig.5) 

ii.           For gantry style LHA H Beam Welding Machine, operator stands on the floor and walks along with traveling of the gantry;

e)      Quantity of the SAW H Beam Welding Machine to Purchase:

i.           For gantry style LHA I Beam Submerged Arc Welding Machine, one set of the machine can work individually (Which means customer purchase one set is fine);

ii.           While for LHC Column H Beam Welding Machine, in an automatic H Beam production line, this equipment comes in four sets (Correspond with the four welding seams in a piece of H Beam), which means customer need to purchase four sets of LHC Column H Beam Welding Machine for one line;

f)        Conceivably, price of one set of LHC Column H Beam Welding Machine is obviously lower than that of one set of LHA H Beam Gantry Welding Machine, around 60% of the LHA.
