Arc welding robots are mainly used in the welding production of various auto parts. In this field, international large arc welding robot type industrial robot manufacturers mainly provide unit products to complete equipment suppliers.
Arc welding robots are mainly used in the following fields:
1. Automobile manufacturing industry: A lot of welding work is required in the automobile manufacturing process, and arc welding robots can complete these tasks efficiently and accurately.
2. Aerospace industry: The aerospace manufacturing industry has very high requirements for welding quality, and arc welding robots can ensure welding quality and accuracy.
3. Shipbuilding industry: a lot of welding work is required in the shipbuilding process, and arc welding robots can improve production efficiency and quality.
4. Rail transit manufacturing industry: A lot of welding work is required in the rail transit manufacturing process, and arc welding robots can complete these tasks efficiently and accurately.
5. Heavy machinery manufacturing industry: a lot of welding work is required in the heavy machinery manufacturing process, and arc welding robots can improve production efficiency and quality.
6. Engineering industries such as pipelines and tanks: In engineering industries such as pipelines and tanks, arc welding robots can be used for automated welding to improve production efficiency and quality.
In short, arc welding robots are widely used in the manufacturing industry, which can improve production efficiency and quality while reducing labor costs.
Common welding defects that can occur with welding robots are as follows:
1. Welding deviation: The welding robot deviates the welding torch from the weldment during the welding process, instead of welding along the weld.
2. Undercut: Due to improper selection of welding parameters, incorrect angle or position, an arc pit is formed after cooling at the end of the weld.
3. Porosity: porosity occurs during welding due to excessive or too small flow of protective gas, low gas purity, oil or impurities on the surface of the workpiece, etc.
4. Spatter: Due to improper selection of welding parameters, gas composition or too long extension length of the welding wire, excessive spatter is generated during welding.
5. Welding tumor: due to the slow welding speed, too large current, too high temperature of the molten pool, and too long solidification time of liquid metal, too many welding tumors are produced during welding.
6. Cold crack: Due to the temperature drop too fast at the end of welding, cold cracks appear at the welded joints.
