Significance of Welding Repair for Diesel Generator Parts

In diesel generator set maintenance, due to the high cost of purchasing spare parts and defects in certain components, welding repair technology can be used to successfully repair them, which is the main significance of welding repair. Below, Dingbo Power Generator Manufacturer will discuss the specific significance of welding repair accessories with you.

Diesel generator welding repair refers to the technology of repairing generators by welding. Welding repair melts the base metal and electrode welding powder together under the action of thermal energy, resulting in good intragranular bonding with high bonding strength. However, the influence of thermal energy will change the structure and shape of the base metal, which is a key issue in welding repair.

According to different thermal energy supply methods, it can be divided into arc welding, gas welding, plasma welding, etc. According to the welding repair process and method, it is divided into welding repair, surfacing, spray coating and brazing. Due to its outstanding advantages, ordinary cast iron is still the main material for manufacturing complex shapes and large sizes, which is easy to process and reduces vibration damping. The failure or ineffectiveness of cast iron parts, for work-in-progress, is mostly casting defects such as pores, sand holes, cracks, looseness, and insufficient pouring. For processed parts, most of them have cracks, wear and other phenomena during use. The production process of castings is long, and the process cost accounts for a large part, especially for large-size, complex-shaped, and large-processing cast iron parts, which condense the cost of raw materials and mechanical equipment processing and manufacturing. Many large castings, such as condensed machine tool beds, machine tool bases, large boxes, etc., generally lack the ability to release themselves and rough machining units.

Therefore, in the diesel generator set maintenance process, we try to reduce waste and compensate for its natural wear. The welding repair of cast iron parts is not only suitable for the repair of partial faults, but also as a forced conversion to partial repair defects, and can greatly reduce production costs. It is of great significance for further research on the repair of cast iron parts. Due to the large temperature change, there will be errors in heating and cooling during welding, so many difficulties will arise.
