Quick Information

  • Brand Name: Kehui
  • Place of Origin: China


Product Introduction
The product is controlled by computer and PLC programming controller, and the degree of automation is high. According to the user's power consumption, it can be welded once or in several times, which is very flexible. The welding system uses forced water cooling and a flow protection device for reliable continuous operation. The welding system pressure is steplessly adjustable to quickly respond to changes in welding material specifications. Uniform welding pressure ensures the quality of all solder joints and increases actual productivity. The product is designed as a detachable structure for easy adjustment and maintenance.

Welding Process

First install the lower guardrail into the lower clamp, press the cylinder tightly → then put the first upper guard rail into the upper clamp, press the cylinder tightly → press the “start” button → 2 welders simultaneously arc welding, and 2 fillers at the same time Automatic wire feeding → walking mechanism forward walking → after the set welding length → 2 welding machine arcing, wire filling machine automatically stop feeding wire → walking mechanism stops walking → automatic feeding mechanism clamping guardrail → automatic clamping mechanism Automatically release the guardrail→Automatic feeding mechanism automatically moves forward → Then put the second upper guard rail into the upper clamp, the cylinder is pressed tightly → automatic welding → sequential welding.

1. The main structure is compact and the relative scope of action is large.
According to the requirements, the 6-degree-of-freedom welding robot can be used to complete the welding of the closed space curve or the multi-channel curve weld, ensuring that the welding gun always has the proper posture to meet the welding process requirements. Large effective load, effective support for automatic positioning, weld seam tracking, welding quality inspection and other functions;

2. The system coordination is good, the welding process is high
Compact structure, real-time monitoring, strong interrupt function, high reliability, high technical level of sensing technology and automatic control system, high coordination of hardware and software systems, complete special or general welding process service with welding machine and its auxiliary equipment, overall welding process The level is high.

3. Easy to learn, easy to use
Users only need to press the function keys to achieve some welding operations or to complete some program modifications, easy to remember and master, without the user to master the esoteric knowledge of the welding robot itself.
