For used resistance welding machinesButt welding machineIt goes without saying that my friends know the advantages, but they may not be complete, so why not take a look with Xiaobai.
1. High thermal efficiency
Utilizing the internal resistance heat source of the workpiece itself, the heat loss is relatively small, the thermal efficiency is relatively high, and energy saving is achieved.
2. The weld is dense
The weld of resistance welding is solidified and crystallized under the action of external pressure. It has the characteristics of forging and belongs to the category of pressure welding. Therefore, it is easier to avoid defects such as shrinkage cavities, looseness and cracks, thereby obtaining a dense weld.
3. Low welding cost
There is no need for flux or gas protection during welding, and there is no need to use filler metals such as welding wires and electrodes, so welding joints with better quality can be obtained and the welding cost is low.
4. Small deformation and stress
Due to the concentrated heat and short heating time, the heat affected zone is small, and the deformation and stress are also small. Usually there is no need to consider correction or heat treatment procedures after welding.
5. Simple operation
One-button operation makes it easy to realize mechanized and automated production, does not require high proficiency of workers, and has low labor intensity.
6. Less slag inclusion and good welding effect
When the nugget is formed, it is always surrounded by a transparent plastic ring, the molten metal is isolated from the air, the metallurgical process is simple, and the welding effect is good.
7. High productivity
Low noise, basically no smoke and dust, and good working conditions. It can be combined with other manufacturing machines to form an automatic production line for mass production. Only flash butt welding requires some isolation due to spark splash.

Used in electronic appliances, aerospace, cable, agriculture, environmental protection, energy, chemical and other industries.
Their resistivity and high temperature strength are higher than stainless steel, so you should pay attention to several points when welding.
1. Remove oil, moisture, dust and other harmful substances from the surface before welding.
2. Use larger electrode pressure and smaller welding current to weld.
3. Use medium frequency butt welding machine to prevent shrinkage holes and cracks.
4. Spherical electrodes should be used for heat dissipation and compression of solder joints.
5. It is easy to deform, so tooling should be used to strengthen positioning.
