Industrial machinery structural engineers need to weld the nut generally

Industrial machinery structural engineers need to weld the nut generally. How do they?

The welded nut is a nut outside the nut suitable for welding, generally, weldable materials and thicker ideal for welding; welding is equivalent to the two separate parts into a whole, with high-temperature melted metal mixed and then cooled, the middle being added to the alloy, the internal is the role of the molecular force, the strength of the general than the parent body strength. The welding parameters' experimentation depends on the weld's fusion size, according to the fusion size adjustment of welding parameters, until defects are eliminated. Of course, welding quality is related to the pre-welding treatment, ash removal, oil stains, etc.

Is the material of the welded workpiece (the same or different), by heating or pressurizing or both, and with or without filler material, so that the material of the workpiece achieves the inter-atomic construction and the formation of a permanent connection of the process, welding nut is a fastener with internal threads and used in conjunction with the bolt.

Mechanical parts with internal threads and used in conjunction with screws to transmit motion or power.

Welding, greater strength, and a wide range of thin and thick uses can be used. Still, high temperatures will lead to deformation of the connected parts, are not removable, and some active metals can not be welded with the usual methods, such as aluminum, magnesium, etc., the need for shielding gas or argon arc welding, the requirements of the processing technology and precision. Nuts are made by welding technology; welding methods have a variety of welding nuts. Generally, how to weld? Here we come to understand.

How are welded nuts typically welded?

What about convex welding nuts? In most cases, we weld convex welding nuts. What is the convex welding nut? A convex welding nut is what we often say is a welding nut in the nut side is a few feet; when the nut spots welder welding current through, the current is concentrated in these feet above, resulting in a weld nucleus and then forms a solid welded joint.

1. Melt welding: This method involves heating the weldment joints to a molten state without applying pressure. Other welding methods include arc, gas, and electro-slag welding lights.

2. Pressure welding: This method requires applying pressure to the weldment to complete the nut welding. Commonly used pressure welding methods are resistance welding, ultrasonic welding, and friction welding; each method is practiced differently.

3. Brazing: This method uses a metal material with a low melting point; the weldment pieces are heated to a specific temperature to complete the nut welding work.

Welding nuts in the welding when the operator needs to pay attention to what?

It is essential to pay attention to operational safety when welding nuts. First, wear protective gloves and masks to prevent personal injury from hot spatter and light radiation. Second, the welding apparatus should be placed on a stable table to avoid tipping and sliding. Finally, the welding status should be carefully observed, and problems found and solved in time.

Steel Hex Weld Nuts: Weld these nuts to flat, uneven, uncoated steel surfaces for a solid permanent hold. A collar pilot assists alignment and prevents welding spatter from getting into threads.

All nuts meet ASME B1.1 and comply with specifications for dimensional standards.

1. The protective gas is argon. When welding, the whole working environment must be ventilated; otherwise, if the air is not circulated, the room will produce harmful substances, affecting people's health. A blocking net must protect the welding to prevent danger.

2. The length of the tungsten electrode protruding from the gas nozzle. Pay attention to the welding part and the tungsten electrode centerline angle to keep between 80-85 °, which can better protect the welding molten pool.

3. The use of vertical external characteristics of the power supply, DC, with positive polarity (wire connected to the negative). The filler wire and the welding surface of the angle should be within 10 ° to ensure that the entire nut surface is fully welded to prevent the nut fittings from loose. When welding the nut, there are several chamfers on it, so the current will be concentrated at these chamfers to form a solid weld joint during the welding construction. When welding, the angle should be changed appropriately to prevent too much current from damaging the chamfers.

4. Welding parts must be cleaned to prevent the emergence of welding holes, such as rust, oil, etc.

5. It is generally suitable for welding thin plates below 6mm. It has beautiful weld molding and small welding deformation.

6. Windproof and ventilation. If there is wind, please block the net, and in the room, you should take appropriate measures to change the air.

7. Welding arc length, welding ordinary steel, to 2 ~ 4mm, is good, and welding stainless steel, to 1 ~ 3mm, is good; too long is not good protection.

8. To make an argon well-protected welding pool and facilitate the welding operation, the tungsten centerline and welding at the workpiece should generally maintain an 80-85 ° angle, filler wire, and the workpiece surface angle should be as small as possible, generally about 10 °. In the case of welding standard nuts, the welding current must be higher and longer to provide sufficient heat for the molten core to form a stable and solid welded joint.

How to make the weld nut welded more firmly?

  The welding nuts are generally welded in a 6mm thin plate to avoid a large deformation and achieve a more beautiful weld after welding. Direct current should be used in welding, and the negative pole is connected to one end of the wire.

Metric Steel Narrow-Base Weld Nuts： A long barrel provides secure thread engagement. Weld these nuts to flat, uncoated steel surfaces for a strong, permanent hold. They can be used in channels and tight spaces where round-base weld nuts won't fit.

Zinc-plated steel weld nuts resist corrosion in wet environments.

Stainless Steel Offset-Barrel Narrow-Base Weld Nuts： These weld nuts have an offset barrel so that you can position threads near corners. Weld them to flat, uncoated steel surfaces for a solid permanent hold. They can be used in channels and tight spaces where round-base weld nuts won't fit.

A kind of standard parts suitable for welding outside the nut, generally weldable materials made of and thicker ideal for welding; welding is equivalent to the two separate parts into a whole, with high-temperature melted metal mixed and then cooled, the middle will be added to the alloy, the internal is the role of the molecular force, the strength of the general than the parent body strength. The welded nut production process is the material of the welded workpiece (the same or different), through the heating or pressure or both, and with or without filler material, so that the material of the workpiece to achieve the inter-atomic construction and the formation of the sexual connection process, the welded nut is with internal threads and bolts with the use of fasteners. Welding nuts are fasteners with internal threads and are used in conjunction with screws to transmit movement or power.

1. Select the appropriate welding position. To avoid excessive heating or some parts receiving too much welding heat, choose a suitable welding position and ensure that the nut's rotation direction is unaffected.

2. Master the welding time and temperature. Suppose the welding time and temperature are too long or too short. In that case, they will affect the welding effect according to the type of welding material, thickness, and power of the equipment, which will be used to adjust the welding time and temperature.

3. Master the welding angle and speed. Welding to maintain a stable angle, try to make the welding material and the surface of the nut at a right angle of 90 degrees, and adjust the welding speed to ensure that the welding material is successfully attached to the surface of the nut.

4. Prevent excessive heating and melting. The welding material and nut surface must not be subjected to excessive heating and melting during welding; otherwise, it will affect the welding strength and safety. Therefore, the welding time and temperature must be mastered according to the situation.

5. Observe the welding effect and quality. After the welding, you must observe and test it promptly to determine whether it meets the standards and requirements.

What are the methods of operation when installing weld nuts?

Manipulation is also significant in the process of welding nuts. First, ensure the welding position is clean to avoid dust and impurities entering the welding point. Secondly, use the correct welding material and choose high-quality welding wire. Finally, be steady and meticulous during welding to avoid bubbles and underfilling.

Square Weld Nuts： Square weld nuts have more weld points than hex weld nuts for a stronger hold. Weld them on flat, uncoated steel surfaces. All have a collar pilot that assists alignment and prevents welding spatter from getting into threads.

Nuts that meet ASME B1.1 comply with specifications for dimensional standards.

1. Prepare tools and materials. According to the nut and soldering needs, choose appropriate tools, such as a soldering iron, solder wire, PCB nut, tweezers, etc.

2. Determine the soldering position. Make sure the nut is placed in the correct position.

3. Place the nut. Use tweezers or other tools to place the nut in the intended position.

4. Heat the solder wire. Use the soldering iron to heat the bottom of the nut and the pad on the PCB, and then gently touch the other side of the iron to melt the solder wire, which will flow into the gap between the pad and the nut.

5. Solder the nut. Gently touch the tip of the soldering iron to the bottom of the nut and the pad on the PCB, then gently touch the solder wire to melt it. The solder will flow into the gap between the pad and the nut.

6. Remove excess solder. After the soldering is completed, wait for the solder joint to cool down, and then carefully remove the excess solder.

7. Check the quality of the soldering. Check that the solder joints are uniform and free of short-circuiting or cold soldering to ensure the nut is firmly soldered to the PCB.

In addition, when soldering nuts, you need to pay attention to controlling current and time, the soldering angle, and the use of protective gas. Different materials and thicknesses may require different welding parameters and methods.
