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

1. Function:

1) Z series T I H Beam Assembly and Tack Welding Machine assembles 2 pieces of long strip plates into the structure of T Beam;

2) Then, with the 3^rd piece of long narrow plate, into finished structure of H Beam or I Beam;

3) And simultaneously carry out CO₂  stitch welding on the assembled workpiece to strengthen it, delivering finished workpieces of assembled H Beam or I Beam:

a) The heap of long narrow plates alongside Wuxi JACK Z15 model machine, as raw material for assembling T Beam and H Beam: (Fig.1)

b) Assembling and CO₂ tack welding on large T Beam in Wuxi JACK Z30 model machine: (Fig.2)

2. Usage and Application of T I H Beam Assembly and Tack Welding Machine:

1) Accordingly, this series of machine is placed at starting station of I H Beam Production Line, right following CNC Flame Cutting Machine, produces assembled H Beam, for next step of H Beam SAW Welding Machine:

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

3) Working site of Wuxi JACK Z18 model machine: Building up assembled H Beam: (Fig.4)

4) Wuxi JACK Z15 model automatic machine, at automatic line on H Beam production: (Fig.5)

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

1. T I H Beam Assembly:

This is accomplished with below 2 steps in the machine:

1) Rought positioning and clamp, by means of hydraulic manipulator, or named pulling rod box, which are deployed along input roller tables:

The 2 pairs of yellow color pulling rod boxes, at both sides of Wuxi JACK Z15 model automatic machine: (Fig.6)

2) Precise Fit Up and Alignment: This is core unit of the machine. In one set of machine, there are eight pieces of eccentric rollers, for implementing on web self-alignment at its top, and four pieces of eccentric rollers for carrying out flange self-alignment at its bottom:

Symmetrically assembled precise fit up and alignment eccentric rollers, of Wuxi JACK Z series automatic machine: (Fig.7)

2. CO₂ Tack Welding in T I H Beam Assembly Machine:

1) This is fulfilled with 2 sets of GMAW CO₂ welding power supply, in the way of automatic welding:

2) Test on CO₂ welding on assembled T Beam, in Wuxi JACK Z models machine: (Fig.8)

3) In the case of large model Z30, the automatic welding should be complemented with manual touchup welding, to get full penetration on welding seams;

3.  Operation Control:

1) Work Logic Control The actions of the above introduced assembly and stitch welding steps, are managed with PLC  (Programmable logic controller) of electric control system, without human intervention, making pinpoint and reliable assembly on web and flange;

2) Working Velocity: The consistent assembly and CO₂ spot welding in the machine are controlled with A.C. inverter, continuously and conveniently.

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

There are several ways of classifying on the this machine:

1. Depending on the Max. Height of H Beam Web:

1) Denote on H Beam Cross section: (Fig.9)

2) Corresponds to the “h” value in the above sketch, the machine has three standard models of Z15/ Z18/ Z20, corresponding with the Max. H Beam web height of 1,500mm / 1,800mm/ 2,000mm respectively

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

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

1) Automatic self alignment: H Beam fitting up and alignment is fulfilled with PLC control: (Fig.10)

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 T I H Beam Assembly and Tack Welding Machine:

Depending on tack welding mode selected, the 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, machine operation needs only 1 operator, and there is no strict requirement on welding skill of the operator:

Chinese HUAYUAN NB350 CO₂ welding power supply, for H Beam tack welding: (Fig.11)

2) Manual tack welding type: The CO₂ tack welding is performed by operator. Under such condition, one set of the machine needs 2 veteran welding operators to work at the same time. The welder should command with proficient welding skill. Under such condition, the machine investment is relatively lower, but daily running cost is higher than automatic models machine.
