Welding is a common industrial processing method, and its main functions include the following aspects:
Connection and assembly: Welding can connect two or more metal parts together through melting and solidification, forming a complete structure. Welding can achieve solid connection and assembly of metal parts, making them a complete workpiece or product.
Strength and stability: Welding can provide high-strength and stable connections. The strength of welded joints is usually equivalent to that of the base metal and can withstand large forces and stresses. The stability of welded joints is also high, and they can maintain the stability of the connection under various environmental conditions.
Sealing and corrosion resistance: Welding can achieve sealed connections of metal parts, preventing the penetration of gases, liquids, or solids. Welded joints usually have good sealing performance and can effectively prevent medium leakage. In addition, welded joints can provide good corrosion resistance and reduce the risk of corrosion and oxidation.
Material and cost savings: Welding can achieve direct connection of metal parts, reducing the use of additional connecting components and materials. Compared to other connection methods, such as bolt connection or adhesive connection, welding can save materials and costs.
Improving appearance and aesthetics: Welding can achieve seamless connection of metal parts, improving appearance and aesthetics. Welded joints are usually smoother and cleaner than other connection methods, reducing the impact of additional connection components on the appearance.
Implementing complex structures: Welding can achieve the manufacturing and assembly of complex structures. By welding, multiple parts can be connected together to form complex structures such as pipelines, bridges, ships, airplanes, etc.
Welding plays an important role in industrial processing, enabling the connection and assembly of metal parts, providing strength, stability, sealing, and corrosion resistance, saving materials and costs, improving appearance and aesthetics, and achieving the manufacturing of complex structures. This makes welding an important process method widely used in various industries.
MIG Melting Inert Gas Shielded Welding
Pressure welding machine is a common welding equipment used to connect metal parts through pressure and heat. The following are the general welding steps for pressure welding machines:
Preparation work: Firstly, prepare the metal parts to be welded. Ensure that the surface of the parts is clean and free from impurities such as oil stains and oxides. Select appropriate welding electrodes and welding parameters according to welding requirements.
Adjusting welding parameters: Adjust the parameters of the welding machine based on the welding material and thickness. This includes welding current, welding time, welding pressure, etc. Ensure that the parameters are suitable for the required welding effect and quality.
Place parts: Place the metal parts to be welded on the workbench of the welding machine. Ensure the correct position of the parts, close contact, and alignment.
Running the welding machine: Start the welding machine so that the electrodes come into contact with the welding joints of the parts. Apply appropriate welding pressure and current according to the set welding parameters. Maintain a certain welding time to achieve the required melting and connection of the welded joint.
Cooling and solidification: After welding is completed, stop the operation of the welding machine. Allow the welded joint to cool and solidify, forming a stable connection at the welded joint. This can be accelerated by natural cooling or the use of a coolant.
Inspection and cleaning: Check the quality and connection of welded joints. If necessary, carry out necessary repairs and cleaning, such as removing welding slag, defects, etc.
Record and storage: Record welding related information, such as welding date, welding process parameters, etc. Properly store welded parts to ensure their safety and integrity.
TIG Non Melting Inert Gas Tungsten Arc Welding
Welding has a wide range of applications in industrial processing, and spot welding, as a common welding method, has the following advantages:
Efficient and fast: Spot welding is an efficient and fast welding method. The welding time is short, usually only taking tens to hundreds of milliseconds, which can greatly improve production efficiency.
Simple and feasible: Spot welding operation is simple and feasible, without the need for complex welding processes and equipment. Simply contact the welding electrode with the workpiece and generate an instantaneous high temperature through the current, causing the surface of the workpiece to instantly melt and weld together.
Wide applicability: Spot welding is suitable for welding various metal materials, including steel, aluminum, copper, etc. Whether it is thin or thick plates, spot welding can achieve reliable welding connections.
High welding strength: Spot welding has high welding strength, and the strength of the welded joint can usually reach or be close to the strength of the substrate. This enables welded joints to withstand significant tensile, shear, and impact forces.
No need for additional materials: Spot welding does not require additional welding materials, unlike other welding methods that require welding wire or flux. This reduces costs and process complexity.
No need for post-treatment: After spot welding, there is almost no need for additional post-treatment. Welded joints are usually flat and do not require polishing or trimming. This saves time and labor costs.
Spot welding has the advantages of high efficiency, speed, simplicity, wide applicability, high welding strength, no need for additional materials, and no need for post-treatment, making it one of the commonly used welding methods in many industrial fields.
SPOT Welding
TIG Non Melting Inert Gas Tungsten Arc Welding, also known as argon arc welding, is a common arc welding method. It is achieved by generating a stable arc in the welding area, heating two metal workpieces to the melting point, and connecting them together using filler material (if necessary).
The characteristic of TIG welding is the use of tungsten electrodes as electrodes, protected by inert gas (usually argon) to prevent molten metal from coming into contact with air. The following are the general steps for TIG welding:
Preparation work: Prepare the metal workpiece to be welded, ensuring its surface is clean and free of contamination. Select appropriate tungsten electrodes and filling materials (if needed).
Set up equipment: Prepare TIG welding equipment, including power supply, gas source, electrode tungsten, and gas protection system. Set appropriate current, electrode diameter, and gas flow rate based on welding materials and requirements.
Ignition and preheating: Use electrode tungsten to ignite on the workpiece, generating an arc. Before welding, it is usually necessary to preheat the workpiece to improve welding quality and reduce stress.
Welding operation: Maintain a stable arc and keep the arc on the weld seam. By controlling the current and arc movement speed, the filling material (if needed) is gradually added to the weld seam to connect the workpieces together.
Control welding parameters: During the welding process, control welding parameters such as current, arc length, gas flow rate, etc. as needed. This helps to maintain welding quality and stability.
Cooling and cleaning: After welding is completed, cool the welding area and clean the welding residue. Check the quality and appearance of the welds, and make necessary repairs and modifications.

Welders only need to control the position and movement speed of the welding gun, and the welding process is relatively simple, suitable for mass production and automated production lines.
