Welding plays an important role in repairing corrosion-damaged parts. In order to contribute to the cost savings of the cement production plant in Vietnam, the application of welding methods to restore the machine parts of abrasive equipment is also preferable box. Below I would like to introduce to you some of the characteristics of the filler and filler as well as the welding methods commonly used in welding.

1. Characteristics of submerge arc welding:

Submerge arc welding is the process by which a metallic surface is applied to the surface to change the size, shape and surface properties of the various welding methods. Weathered, damaged, broken, broken, cracked, cracked, cracked, cracked, cracked, cracked, cracked or cracked. The cement industry is roller pads, grinding pads in grinders, hammer dams, bar beaters in limestone crushers … Welds can also be used to make new details. Weld to create a fill layer with special properties or create a metallic layer with abrasion-resistant, friction-free capabilities such as blades in the dispensers, clinker lifting carriers … Materials Welding machine in India can be carbon steel, abrasion-resistant steel, special steel such as heat-resistant, high resistance, acid-resistant … Welding – Metal saving, restoration of surface damage, High mobility, high productivity, easy to automate.

The shortcomings of welding technology: Re-machining after welding, creating residual stress in the welding layer (thermal stress); Details deformed, can be cracked (rough, microscopic); Prepare the surface before welding.

Grade filler: The surface properties vary, depending on the method of welding and welding materials. Highly corrosion resistant, corrosion resistant, stable metal organization, basic metal base chemistry, can survive the residual stress after welding …

2. Some submerge arc welding methods used in welding technology

At present, welding technology has developed to a high level, comprehensive in terms of genre as well as quality. Much work as well as the whole process of technology has come up semi-automatic and automatic. However, hand welds are still widely used and under certain conditions it is certain to be versatile and flexible. The following are examples of welding methods that are currently widely used for welding.

Hand-wound welding:

Hand-arc welding is the first method of welding welding in the repair industry, which is a very popular machine using molten electrode for welding. This method is applied in recovery work, easy to operate, less time for preparation work, flexible welding operation can be sold in any position. Therefore, it can be suitable for all types of details, especially complex shapes.

The formation of the weld metal can be considered as the mixing of the base metal and the base metal in the molten state when soldered. In which the composition of the embankment metal is the metal supplement from the electrodes, secondary welding wire …

Arc welding principle

Automatic welding under the protection layer: Most of the components that can be applied are flat or cylindrical. With this method, the yield of welding is significantly increased, the working condition and welding quality are improved, power consumption and welding materials are low. Metallurgical metal welds easily, so can increase the mechanical weld layer, increase the abrasion resistance, the impact of post-recovery details. Alloying in auto welding is cheaper and simpler than producing special welding electrodes. This method is widely applied to cylindrical parts such as crankshaft, piston hammer shaft, pump work chamber, rock drill, oil drill etc. This method is also applied to weld the limbs. Flat surface such as jaw clamps, large friction bearings, stainless steel weld for abrasion-resistant surfaces.
