Considerations for Welding Materials
Release time:
2020-06-11
Considerations for Welding Materials 1. Stainless steel welding rod is divided into titanium calcium type and low hydrogen type. DC power supply should be used for current during welding, which is of great help to overcome the redness and penetration of welding rod. Titanium calcium type coating welding material is not very suitable for all-round welding requirements, only suitable for flat welding and flat fillet welding two cases. 2. The stainless steel electrode should keep the surface dry when it is used. In order to prevent surface cracks, pores, pits and other problems. Can not repeat drying many times, otherwise the medicine skin is easy to fall off. 3, the welding material of the weld to clean up, to prevent the welding rod stained with dirt, will affect the quality of welding. 4. To prevent intergranular corrosion caused by too long heating time, the welding current should not be too large, the arc should not be too long, and the interlayer should be cooled quickly, * * in the way of narrow channel welding.
