Reduce labor intensity and improve working environment.Improve work efficiency, 1.5 times that of manual welding.Avoid poor quality welds caused by human factors. Usually manual defect rate is about 20%. The use of an automatic welding carriage did not result in a poor welding rate. So the overall efficiency than manual welding increase of nearly 200%.High degree of automation to ensure the stability of welding quality.Unskilled workers can also quickly master the operation. The HK-7W-F full position oscillating automatic welding carriage was developed on the basis of a standard fillet carriage to obtain a large weld joint and one-process welding. It combines the simplicity and lightness of the standard fillet carriage, and further improves the welding efficiency.
