【Summary Description】 We all know that the welding wire as an important core part of the welding equipment, can not have a little error, because a little wrong will affect the entire welding results. For example, the welding wire is damp is an example, then the welding wire is damp on the welding equipment will have what effect?
We all know that the welding wire as an important core part of the welding equipment, can not have a little error, because a little wrong will affect the entire welding results. SuchWelding wireMoisture is an example, so what are the effects of welding wire moisture on welding equipment?
The damp welding wire is easy to increase the dispersed hydrogen content in the deposited metal, and the defects such as pits and pores will occur. The function of the welding process and the mechanical function of the weld metal will deteriorate, and the tense words can lead to weld cracking. So we have to do a good job of welding wire protection measures:
1. The welding wire should be stored in a special Welding materials library, and pay attention to the ventilation and drying of the warehouse. The relative humidity of the air should be controlled below 60cm and connected to the wall by 30cm.
2. The type and specification of welding wire should be clearly distinguished, and different types should not be mixed together.
3. In the process of handling welding wire, it is necessary to avoid littering and prevent packaging damage. Once the packaging is damaged, it may cause the welding wire to absorb moisture and rust.
4. As for the barreled welding wire, do not rotate it during handling, and the container is not lowered or tilted, so as to prevent the welding wire in the cylinder from being surrounded and hindering the application.
5. Under normal circumstances, the welding wire does not need to be dried, but the welding wire should be used up as soon as possible after opening. If the welding wire is not used up and needs to be left in the machine, cover the wire feeder (or welding wire tray) with canvas, plastic cloth or other items. to reduce contact with moisture in the air.
If it issilver welding wire, then there is a greater need for maintenance and maintenance, do you remember?
