Automatic Corrugated Fin Welding Machine

Product Introduction

The Automatic Corrugated Fin Welding Machine is designed for welding formed corrugated fins used in transformer tank manufacturing.

After the corrugated fin forming process, the machine automatically welds the fin seam to create a complete corrugated wall structure.

Using MIG/MAG welding technology, servo-controlled torch movement, and programmable welding parameters, the equipment provides stable welding quality and improves production efficiency.

The machine can also perform automatic positioning and welding of round steel bar reinforcement according to transformer tank design requirements.

Position in Corrugated Fin Production Line

The welding machine is installed after the corrugated fin forming process.

Typical production process:

Steel Coil → Automatic Decoiler → Corrugated Fin Forming Machine → Corrugated Fin Welding Machine → Reinforcement Welding → Finished Corrugated Wall

After forming, the corrugated fin requires seam welding to complete the tank wall structure.

The welding machine ensures consistent seam quality before the finished corrugated wall moves to the next assembly process.

Key Features

1. Automatic MIG/MAG Seam Welding

The machine uses MIG/MAG welding technology to weld corrugated fin seams.

Compared with manual welding, automatic torch movement provides:

• Stable welding speed
• Consistent welding position
• Repeatable welding quality

2. Servo-Controlled Torch Movement

The welding torch moves along the seam through a servo-driven carriage.

Welding speed:

0.5–1.5 m/min

The operator can set welding parameters through the touchscreen control system.

3. OTC DM350 Welding System

The machine uses:

OTC DM350 welding power source

with maximum welding current:

350 A

The digital welding system provides stable arc performance for continuous seam welding.

4. Stored Welding Parameters

The control system allows storage and recall of welding parameters including:

• Welding current
• Travel speed
• Welding settings

This helps maintain consistent production quality for repeated transformer tank models.

5. Automatic Reinforcement Bar Welding

For corrugated tanks requiring reinforcement bars, the machine can automatically position and weld round steel reinforcement bars during the same process.

This reduces additional handling and improves production efficiency.
