Technical Superiority of Wuxi JACK I H Beam Gantry SAW Welding Machine

Importance of SAW Welding Seam Tracing Unit on Performance of I H Beam Welding Machine:

1. Welding seam tracer plays key role in determining welding quality of I H Beam Welding Machine:

This is specifically reflected in formation of welding seam on working parts:
1) What Happens without Seam Tracker? During submerged arc welding in the I H Beam Gantry Welding Machine, suppose welding torch deflects away from its proper target position, and could not keep its correct position in stable way;
2) Then, the completed welding seam will grow crooked with inconsistent seam height and cover face;
3) This not only deteriorates appearance of finished welding seam, but also more seriously is, inferior welding quality delivered from the I H Beam Welding Machine;

2. Ingenious Design and Delicate Workmanship of Welding Seam Tracing unit in Wuxi JACK I H Beam Gantry SAW Welding Machine:

1) As you can check from the above photos, Wuxi JACK has ingenious design, real talent and material on welding seam tracing unit equipped in our I H Beam Gantry Welding Machine;
2) Capability: The seam tracer has spatial three dimensional tracing ability in precise manner, during operation of I H Beam Gantry SAW Welding Machine;
3) Tracking Elements: There are leaning rollers for both horizontal and vertical direction tracing, which touch with surface of horizontal welding seam and vertical mounting carriage tightly in dynamic way, in the process of SAW in I H Beam Gantry Welding Machine;
4) Working Principle: During SAW implemented in the I H Beam Gantry Welding Machine, the up and down movement of seam tracer works in floating style, while horizontal movement is driven with pneumatic valves. This gives flexible and most fitting control on welding seam tracer in all directions;

3. Working Manner of Welding Seam Tracing unit in Wuxi JACK I H Beam Gantry SAW Welding Machine:

1) Fully Automatic: Welding seam tracing unit operates in the I H Beam Gantry Welding Machine automatically;
2) Compact Design: Shown in the above photos, SAW welding flux feeding tubes are integrated into the welding seam tracing unit, making compact design and dimension of the entire welding group, in Wuxi JACK I H Beam Gantry Welding Machine;
