What is the Kalviz?
Slaughter is called gear making and shaving into round and cylindrical objects such as beads, pipes, and so on. The collar is a precise technical operation and is performed by manual and machine drills in several stages. The Tap Bit Tap Bit is a small steel tool with a brown part whose sharp teeth are manufactured directly or spiral. The drill is placed by the user's hand or the female drill on the tube and hole, and with the help of his sharp treads, the operation of shaving and making regular thread inside the object. The process and speed of the rotation of these drills are fully controlled by the model and size, according to a global technical standard.
Application of Clauses
All turning workshops, bolt manufacturing plants, water pipelines and installations use collapse. This can be done either in large numbers with heavy industrial and heavy -duty machines or manually in a small workshop. Parts or closure of plumbing connections such as converter, lid, knee, etc. will not be available on water and gas pipes. Generally, to attach two pieces of metal, wood, plastic to each other with the help of threading and twisting, requires internal work and a tone (screw).
Types of Kalviz
Drilling, although similar in appearance, exists in a variety of types and often have alloy steel sex. Depending on the type of use of the device, the drill is divided into two categories of manual and machine; And each category also has different sizes and designs and one part of the tread.
Specialized methods of aluminum welding
Aluminum welding with electrode is a specialized process that requires high experience and experience. Different methods can be used for aluminum welding.
Electrical welding

Welding with frictional welding
Important Tips of Welding with Electrical
Electrodes can absorb moisture. For this reason, be sure to keep them in your own place and dry them at 2 ° C if the electrodes are moist. The thickness of the alloy should be the same as the thickness of the aluminum workpiece. Pay attention to the angle of welding. The angle of the electrode relative to the plate should be 2 degrees. If you are dirty with the help of a wired brush or sandpaper, clean it from any roughness. The arch of welding in aluminum welding should be very short. Heat parts that are 2 mm thick at 2 ° C to make them more flexible. This number is 2 ° C for aluminum sheets with a thickness of 2 mm. When replacing the electrode with the help of semi -warm water, wipe the welding site up to about 2 cm from any welding flowers. Use oxygen or acetylene welding for less than 1 mm and use a special welding round when doing work to increase the welding resistance, due to accelerating melting procedure, also speeding up your operation.
Note these tips during aluminum welding
Welders are slightly confused during aluminum welding; Because the strength of the steel boiling is the same as its base metal, but for aluminum, this is different. In aluminum, the boiling strength is less than the base material. For this reason, the most important part of aluminum welding with the electrode is the electrode selection. For this reason, having complete information about aluminum and its welding will play an effective role in the quality of work. Like any other job, in aluminum welding you need to know the basics of it. Don't forget the following tips at the time of welding:
Know the sex and capabilities of aluminum alloys: It is important to know about the sex and capabilities of different aluminum alloys. The flexibility of different alloys depends on their heat point; For this reason, not any alloy is flexible with the same method and amount of heat.
Identify aluminum alloys: It is necessary to identify aluminum alloys for the selection of welding. Series 1, 2, 2, and 2 series alloys can be welded with arched welding, but the Aluminum Series 1 and 2 alloys cannot be welded. Of course, alloy 1 and 2 can be welded by arc welding.
The best method of aluminum welding
Safety and Preparation: Welding safety tips are essential. Wearing protective equipment (glasses, helmets, gloves, etc.) is very important like any other welding method. Knowing and understanding how the project is already implemented is a great way to prepare the welding process.
Aluminum Cleaning: Before you do the welding, aluminum should be stainless. You should clean the metal surface from any oxide and remove the surface from dirt, soil and other contaminants. Use a stainless steel brush to clean aluminum to clean aluminum. Never use chlorinated solvents when cleaning any contamination. These solvents may produce hazardous gases because they react to electrical arcs and become gases such as phosse that can be fatal.
Choosing the right filling material: Choosing the right type of pimple for aluminum is not enough. If you do not choose the right filling material, you will not get the desired result. There are several factors in selecting different filling materials. For example, the MiG/MAG welding filler is MIG/MAG.
Protective Gas Selection: For aluminum welding, selection of protective gas is very important. Protective gas protects the weld against atmospheric changes and affects the arch, heat transfer and penetration. Using the CO2 and MIG welding machine is one of the most common ways for protective gas. Under certain conditions, a mixture of helium/ argon should be used. In general, helium is selected for thicker materials and higher pimples.
Aluminum Welding Method: Welding methods are varied and are divided into different types that we will examine.
Aluminum welding methods
Aluminum welding is a highly specialized task that requires high skill and accuracy. Different methods can be used for aluminum welding.
Electrical welding
This welding method uses special electrodes, which are 2 % aluminum and 2 % of the silicon. In the arc method, the thickness of the workpiece is completely directly related to the electrode diameter. In fact, the higher the thickness of the workpiece, the higher the electrode diameter used.
