A.  Function, Usage and Application of Z Series I H Beam Assembly Machine:

1. Task of Z Series I H Beam Assembly and Tack Welding Machine:

1) Delivery and Main Job: Z series machine is used for assembling two pieces of flange and one piece of web into the structure of “H” or “I”, and carry out tack welding (or called CO₂  stitch welding), to strengthen the structure of the assembled I H Beam at the same time;

2) In this sense, this equipment also has the full name of I H Beam Assembling and Tack Welding Machine;

3) Design structure of I H Beam fabricated: (Fig.1)

4) Working site of Wuxi JACK Z15 I H Beam Assembling and Tack Welding Machine: building up assembled H Beam: (Fig.2)

2.  Application and Importance: Z series machine is the 1^st set of major core equipment in I H Beam Production Line, for building up basic skeleton of welding I H Beam.

B. Process Technology of I H Beam Assembly and Tack Welding Machine:

1. From T Beam to H Beam in I H Beam Assembling Machine:

In one full operation period for I H Beam assembly and tack welding:

1) First web and the first piece of flange are fit up and spot welded into T Beam;

2) Then, the 2^nd piece of flange is loaded onto the machine, then T Beam is further fabricated into H Beam (I Beam);

3) Control Unit: The work logic of entire H Beam fitting up and tack welding is controlled with PLC (Programmable logic controller);

2.  Main Equipment in I H Beam Production Line:

a) Importance: In the process technology of welding I H Beam production, the I H Beam Assembly and Tack Welding Machine is the first set of core machine;

b) The other two critical equipment subsequent:

1) LHA / LHC / LHT series H Beam Welding Machine (H Beam Submerged Arc Welding Machine);

2) HYJ / YTJ series H Beam Straightening Machine (H Beam Flange Straightening Machine).

C. Standard Models and Classification on Z Series I H Beam Assembling Machine:

There are several ways of classifying on the machine:

1. Depending on the Max. Height of H Beam Web from I H Beam Assembly Machine:

a) Denote on H Beam Cross section: (Fig.3)

b) Corresponds to the “h” value in the above sketch, the Z series I H Beam Assembly and Tack Welding Machine has three standard models of Z15, Z18, Z20:

1) Z15: The produced max. H Beam web height is 1,500mm;

2) Z18: The produced max. H Beam web height is 1,800mm;

3) Z20: The produced max. H Beam web height is 2,000mm;

4) The max. model of Z30: Max. H Beam web height of 3,000mm;

2. Way of Flange and Web Fit Up in I H Beam Assembling Machine:

Depending on alignment style of web and flange, the Z series machine has two major types of:

1) Automatic self alignment type: H Beam fitting up and alignment is fulfilled with PLC control: (Fig.4)

2)  Manual alignment type: One side of upright web is clamped, and the other side of the upright web is aligned with horizontal flange by means of manual turning leadscrew. This alignment form depends on proficient skill and experience of operators;

3. Stitch Welding Mode in I H Beam Assembling and Tack Welding Machine:

Depending on tack welding mode selected, the Z series machine has two major groups of:

1)  Automatic tack welding: The CO₂ stitch welding is controlled and performed with CO₂ welding power supply. Under such condition, the machine needs only 1 operator, and there is no strict requirement on welding skill of the operator:

Wuxi JACK automatic I H Beam Assembly Machine: (Fig.5)

2) Manual tack welding type: The CO₂ tack welding is performed by operator. Under such condition, one set of the machine needs 2 veteran operators work at the same time, with proficient welding skill.
