There are many benefits brought by the progress of science and technology, which have a great impact on people's work and life.And nickel alloy also has a wide range of applications, to solve a lot of people's troubles. So nickel alloy welding need to pay attention to what things?An alloy is a combination of two or more materials with excellent properties to make them even better. Remove iron nodules left by thermal cutting.
Clean the two welded joints with an appropriate solvent before welding to remove the oil or grease from the joints;
Before welding, spot welding is used to locate, avoid cracks, as well as the size deviation specified in the design and ensure that the component has sufficient strength. When position welding is mixed with welding, the welding operating procedure specification often specifies that the grinding should be performed after the start and stop of the position welding.
Use proper welding materials and store well when not in use. Storage of electrode is carried out according to manufacturer's recommendations.
Monolithic alloy, rolling composite and explosive composite
The welding factors to be considered for monolithic alloys, rolling composites and explosive composites are similar except for the notes below. Do not use carbon steel tools on the alloy side during the handling of the medium plate. The hanging rings welded to the alloy should be of the same or similar material.
Joints shall be fully soldered unless technical conditions do not require. Except for those who finish the welding only from one side, it is usually necessary to clean the root before completing the double-sided weld and grind the side of the root to expose the good metal matrix.
The whole weld should be visually inspected to see whether it meets the requirements of the standard. The representative requirements of the standard are that the weld should have no non-fusion, no penetration phenomenon, and no cold insulation, no welding tumor and crack. The standard limits the height of the weld protrusion, the number of edge bites and the number of dense pores.
