Some clients believe the main differences between the semi-automatic machines and the automatic machines are production capacity and prices. However, factors such as welding quality, convenience, spare parts’ service life and defect detection also require attention.
About the semi-automatic welding machine
Disadvantage: The welding quality largely depends on operators’ skills and diligence.
Advantage: Compared with automatic welding machine, it’s more convenient to change molds when producing different types of cans by one machine.
About the automatic welding machine
Disadvantage:
If the pressure is too high during the welding process, the welding rolls will wear out quickly.
Advantages:
The automatic welding machine employs PLC system. It enables precise digital operation.
• The PLC automatically calculates the stroke distance (the movement of the can body) based on the input can height.
• Machine-controlled stroke ensures a straight seam, and the mold and welding rolls maintain consistent weld width.
• The welding speed will be calculated by PLC. The operators just need to enter a set value.
Production capacity=welding speed / (can height +gap between cans)
• Additionally, real-time data monitoring allows for prompt identification and swift resolution of issues.
It’s essential to understand the types of welding machines and specific situations so that people will not spin wheels into confusion.
