Welding supporting functions

Robot supporting technology 1: high-voltage positioning technology

Positioning function:
More accurate and sensitive positioning
Resistant to oil and rust on the workpiece surface
Quick positioning
Positioning voltage:
Aotai, low voltage 54V, high voltage 140V
Megmeet, low voltage 8V, high voltage 80-400V

Welding supporting functions

Robot supporting technology 2: arc tracking

Through swing welding, the robot finds the center of the weld according to the change of welding current. The welding machine uploads the current signal to the robot through the digital interface to achieve tracking adjustment. Current detection cycle: 0.02s

Welding supporting functions

Robot supporting technology 3: arc swing

The purpose of the swing is to control the flow of molten metal and obtain the necessary weld width to obtain better weld formation.

Welding supporting functions

Robot supporting technology 4: laser tracking

The laser tracking process package uses a laser tracking sensor to send back the coordinates of the weld to the robot controller in real time to guide the robot to track the weld when there is deviation in the left and right directions and the up and down directions.

Welding supporting functions

Robot supporting technology 5: multi-layer and multi-channel

The advantage of multi-layer welding is that it can weld thick-walled structures. Compared with single-layer welding under the same circumstances, it can also reduce heat input, deformation, and the probability of defects.

Welding supporting functions

Robot supporting technology 6: Overlap and re-arc

During the welding process, if welding is interrupted by some factors, when the interruption program is executed again, the welding gun retreats a distance and restarts the arc before the pause position to overlap with the previous weld bead to achieve weld transition. The overlap condition is used to call the overlap parameter after the overlap function is turned on.

Thin plate selection

In the automotive parts, fitness equipment, electric vehicles, leisure furniture and other industries, the thickness of the plate is mainly below 3mm.

The characteristics of this industry: large production capacity and high production efficiency requirements.
The difficulties of thin plate welding: thin plate, large gap between the assembly, easy deformation during welding, etc.

Medium and thick plate selection

As the manufacturing technology of large structural parts gradually matures, thick plates and very thick plates are widely used in the production of industries such as shipbuilding, engineering machinery, building bridges and pressure vessels, and the requirements for welding quality are getting higher and higher.

Coal mining machinery

Construction Machinery

Heavy steel structure

Welding difficulties:
· The traditional gas shielded welding process has large spatter and poor weld formation;
· The workpiece surface is rusty and oily, and the robot is difficult to locate;
· Fewer welding defects, higher penetration depth and deposition efficiency requirements.

Medium and thick plate selection

Aotai NBC-500RPPlus has single pulse, fast pulse and deep penetration pulse welding modes. It can weld carbon steel, stainless steel, copper and its alloys and other non-ferrous metals. Main application industries: engineering machinery, steel structure, coal mining machinery, military industry, etc.

Aluminum alloy welding selection

MIG-500RP Super PLUS

Aotai MIG-500RP Super PLUS has three welding modes: single pulse, double pulse and super double pulse. It can weld non-ferrous metals such as carbon steel, stainless steel, aluminum and its alloys, copper and its alloys. Super double pulse is mainly used for welding aluminum silicon (4 series) welding wire materials, suitable for welding workpieces with a thickness of 1.2-3.5mm. The fish scale pattern is close to tungsten inert gas arc welding, and the efficiency is higher than argon arc welding.

Main application industries: bicycles, scooters, leisure furniture, new energy vehicles, etc.
