Product Intro

Grating Welding Machine

Single/ Dual Cross Bar Grating Welding Machine

GT Model

Energy Efficient

Three Phase Inverter DC Output Current Solution

The three phase balanced input with constant DC output saves 70% energy consumption compared to standard Single Phase AC machines. Lowly connected load of 800kVA for dual bar welding with primary current is as low as 1400A.

Energy Efficient

German Bosch Rexroth Inverter DC Power Supply

The German Bosch Rexroth inverter DC power supply helps make reliable welds with the primary current control and constant output current.

High Return on Investment

Low Energy Cost and Efficient Production

With the 70% energy cost reduction, it could save up to an annual expanse of US$20,000 compared with AC machines. Lowly connected load requirement.

High Production Efficiency

Preloading System

Onsite operators can load the bearing bars onto the preloading system without stopping the machine. The preloading system helps the auto feeding into the welding station, enhancing the safety and efficiency of the grating welding machine

Save Labor & Increase Safety

Cross Bar Auto Loading System

The pneumatic auto loader feeds and positions two twisted bars onto the welding position accurately before welding.

Stable & Excellent Welding Quality

High current density with stable pressure from the heat-treated cast iron head (supported by four heavy duty steel columns) results in high penetration and excellent welding quality.

Cooling is vital to performance

The inverter DC transformers, electrodes, and secondary coils are water cooled. The diodes are cooled by the chiller*. A series of fans is built to eliminate condensation and to maintain system stability.

* Chiller is an optional equipment.
