How to weld large welds: Analysis of popular welding techniques in the entire network
Recently, welding technology has once again become a hot topic in the industrial field, especially the way to deal with the common problem of "large welds". This article will combine the hot contents of the entire network for the past 10 days to analyze the causes, solutions and practical techniques of welds in detail.
1. Common reasons for large welds
According to recent industry discussions and expert analysis, excessive welds are usually caused by the following reasons:
| Cause classification | Specific performance | Percentage |
|---|---|---|
| Inappropriate parameter settings | Too high current and too high voltage | 42% |
| Operational technical issues | The welding torch angle is wrong and the movement speed is too slow | 35% |
| Material Factors | Inconsistent thickness of the base material and mismatched wire diameter | 18% |
| Equipment issues | Unstable wire feeding, wear of conductive nozzle | 5% |
2. Practical method to solve the problem of large welds
Based on recent hot discussions and technology sharing, we have compiled the following solutions:
| method | Key points of operation | Applicable scenarios |
|---|---|---|
| Adjust welding parameters | Reduce the current by 10-15%, and appropriately increase the welding speed | Large welds caused by improper parameter setting |
| Improve operation methods | Maintain the angle between the welding gun and the workpiece 75-85°, and use zigzag-shaped straps | Operational technical issues |
| Choose suitable welding materials | Select a small number one welding wire according to the thickness of the base material | Material mismatch |
| Equipment maintenance | Regularly replace the conductive nozzle and check the wire feeding mechanism | Weld abnormalities caused by equipment problems |
3. Recent hot welding technology trends
Based on the heat of discussion across the Internet, we found that the following technologies have received widespread attention:
1.Pulse welding technology: By precisely controlling the current pulse, the weld size can be effectively controlled, especially suitable for thin plate welding.
2.Laser-arc composite welding: Recently, many companies have released relevant cases, which can significantly improve welding quality and efficiency.
3.Intelligent welding system: The welding robot equipped with vision sensors can adjust parameters in real time and automatically compensate for the weld size deviation.
4. Expert suggestions and precautions
Based on recent interviews with experts in welding field, we summarized the following suggestions:
1. For beginners, it is recommended to first perform parameter debugging on the small sample to master the appropriate welding speed.
2. When encountering excessive weld problems, the equipment, materials and process parameters should be systematically checked rather than a single adjustment of a certain factor.
3. Regularly participate in welding training and understand the latest process technologies, which has become a recent industry consensus.
V. Typical case analysis
The following are the successful cases shared by a well-known welding forum recently:
| project | Original process | After improvement | Effect |
|---|---|---|---|
| Steel structure welding | Weld width 8-10mm | Weld width 5-6mm | Material savings 15% and strength improvement |
| Pipe welding | Welding height 3mm | Welding height 1.5mm | Pass rate increased from 85% to 98% |
Through the above analysis and data, we can see that although the major problems of welds are common, they can be effectively solved through scientific methods and appropriate technical adjustments. Recent industry development trends show that intelligent and precise welding technology will become the key to solving such problems.
