Usage and function of welding locator
Jul 04,2025
The use of welding locator:
1.If preheating is required during welding, it is also necessary to preheat before positioning welding, and the preheating temperature should be 30-50 ℃ higher than that of ordinary welding.
2. Positioning welding is intermittent welding, where the workpiece temperature is lower than normal welding. Due to insufficient heat input, the welding current needs to increase by 10% to 15% compared to normal welding.
3. Positioning welding should not be carried out at the intersection of the weld seam, and the direction of the weld seam changes greatly. Positioning welding can be carried out at a distance of about 50 millimeters.
4.When positioning welding, the degree of welding constraint is high and it is easy to crack. To prevent cracks, forced assembly should be avoided as much as possible.
5.When cracks and unacceptable defects are found in the positioning weld, they should be eliminated in a timely manner and re displaced for welding.
6. The beginning and end of the positioning welding should be smooth to prevent the welding joint from not penetrating here.
