Exceptionally Robust Joints: Welding produces exceptionally robust connections that frequently match or exceed the strength of the parent materials. This makes it particularly valuable for critical applications requiring superior structural integrity, such as in building frameworks, vehicle manufacturing, and aircraft assembly.
Permanent & Leak-Proof Connections: Welding creates molecular-level fusion between materials, offering distinct advantages over mechanical fasteners like bolts or rivets. This permanent bonding solution eliminates the risk of gradual loosening.
Material Versatility: Welding is capable of bonding diverse materials, including carbon steel, corrosion-resistant stainless steel, lightweight aluminum, conductive copper, malleable brass, corrosion-protected galvanized steel, and various other metals and alloys.
Cost & Time Efficiency: By eliminating multiple assembly components like mechanical fasteners and bonding agents, welding significantly streamlines manufacturing processes. Robot welding further enhances production throughput, delivering faster cycle times while maintaining consistent quality.

Yixing can provide different types of welding services TIG welding, MIG welding, laser welding, resistance welding and Robot welding, suitable for different materials, different thicknesses and different scenarios. For example, we use TIG welding to achieve high-strength, clean and beautiful welds, and also for pipe welding. We use laser welding to make some high precision thin-walled parts. We use MIG welding to quickly weld some thick plates for construction industry. Robot welding can be combined with TIG/MIG/Laser welding to achieve high-volume and high-repetitive welding projects.
Yixing has wide range of material welding services like carbon steel welding services, aluminum welding services, stainless steel welding services, copper welding services and brass welding services. Different material has different mechanical properties (such as tensile strength, ductility, and hardness), chemical properties (such as corrosion and oxidation resistance), and physical properties (such as melting point, thermal conductivity, and electrical conductivity). We will choose the best welding method for different materials based on advantages and disadvantages of the various welding methods.
Aluminum and aluminum alloys, due to their unique physical and chemical properties, encounter a series of difficulties during the welding process. Specifically, there are several points to consider:
1. Strong oxidation ability
2. Aluminum has a high thermal conductivity and specific heat, resulting in fast thermal conductivity
3. High coefficient of linear expansion
4. Easy to form pores
5. Welding joints are prone to softening
6. Evaporation and burning of alloy elements
7. Aluminum has low strength and plasticity at high temperatures
8. The corrosion resistance of welded joints is lower than that of the base material
9. No color change, making welding operations difficult
Shanghai Yixing has well trained and certified welders to meet customers demands of aluminum welding.
For thin metals, if you are not careful and do not have sufficient control over the heat generated by the welding machine, the metal is easily melted completely. This is what is called burning through.
To weld thin metal, choose an appropriate process (low current TIG or MIG), use smaller diameter welding wires or filler rods, and adjust the travel speed to prevent burn through. Using pulse technology, seam welding, or positioning welding to control heat and allow for cooling time between welds to minimize warping.
1. Using anti deformation method to control welding deformation
In order to offset and compensate for welding deformation, during assembly before welding, the workpiece is first artificially deformed in the opposite direction to the welding deformation. This method is called reverse deformation method. The anti deformation method is the most commonly used method in production, which is usually suitable for controlling the angular deformation and bending deformation of welded parts.
2. Control welding deformation using rigid fixation method
The method of using fixtures, supports, specialized molds, positioning welding, and other methods to increase the rigidity of the structure and reduce welding deformation is called rigid fixation method. The rigid fixation method is simple and easy to implement, and is a commonly used method in production to reduce welding deformation. In production, rigid fixation and anti deformation are commonly used to control welding deformation.
3. Choose a reasonable welding sequence to control welding deformation
The same welding structure, using different welding sequences, often results in different welding deformations. Therefore, the welding sequence that causes the least welding deformation should be selected. Generally, the sequence of assembly before welding is adopted, and the welding deformation of the structure after welding is relatively small.
4. Choose a reasonable welding sequence to control welding deformation
When there are multiple welds on the welding structure, different welding sequences will cause different welding deformations. A reasonable welding sequence refers to: when the weld seam is symmetrically arranged, symmetrical welding should be used; When the weld seam is arranged asymmetrically, the smaller side of the weld seam should be welded first. In addition, methods such as skip welding and segmented back welding have shown good results in controlling welding deformation.
5. Hammering method
By hammering to extend the weld seam, the deformation caused by weld seam shrinkage can be overcome to a certain extent. For example, if wave deformation occurs after thin plate butt welding, a hammer can be used to hammer the weld seam in the length direction to overcome its deformation.
6. Choose a reasonable welding method
Choosing welding methods with relatively concentrated energy, such as CO2 gas shielded welding and plasma arc welding, instead of gas welding and manual arc welding for thin plate welding can reduce deformation.
