2. Powerful Automated Operation Process

a. Initial Setup:

All mechanisms are in their original positions. One mold cart is in the demolding position, and all cylinder sensors are functioning normally. The operator places the workpiece into the mold on the cart.

b. Welding Process:

The mold cart moves the workpiece into the welding position, where welding is performed sequentially.

c. Completion and Cycle:

After welding, the mold cart returns the mold to its original position. The operator removes the welded workpiece, reloads new material, and the cycle repeats.

Daily Production Calculation

 

Daily Output:

(10 hours×3600 seconds×98% efficiency15 seconds per cycle)×2 (simultaneous welding of two products)≈1300 pieces/day (10 hours)(15 seconds per cycle10 hours×3600 seconds×98% efficiency​)×2 (simultaneous welding of two products)≈1300 pieces/day (10 hours)

 

Assumptions:

10-hour workday with 98% efficiency (accounting for breaks, rest periods, and maintenance).

The equipment operates in a collaborative workflow, allowing overlapping material loading times. Thus, the total cycle time is based on the longest single operation.

 

 

Conclusion

The oversized work area of the gantry welding machine offers undeniable advantages in handling large workpieces, enabling simultaneous multi-workpiece welding, optimizing production processes, and increasing output. It brings higher efficiency, better quality, and stronger competitiveness to industrial manufacturing, making it a key factor in advancing welding production to new heights.
