Resistor brazing brass
Brass is a copper-zinc alloy. Zinc oxide and cuprous oxide are easily generated on the surface during resistance brazing at high temperatures. Although zinc oxide is relatively firmly bonded, it is relatively easy to remove with flux, so it does not affect the weldability.

Butt welding of aluminum alloy
Common butt welding methods for aluminum alloys include spot welding and butt welding. The 3457 series butt welding is easier and can be done with a resistance AC butt welding machine. The added elements in the 126 series are not resistance weldable. For spot welding in touch welding, no matter which series it is, it is more difficult.

Spot welding of 301L stainless steel
301L stainless steel is mainly used for tram frame steel. It is an austenitic stainless steel with lower Cr and Ni content and higher N content, which reduces the carbon content of the original 301 steel to improve the intergranular corrosion resistance of the welding zone.

As the Russia-Ukraine war continues and global oil prices continue to rise, lightweight new energy vehicles are becoming more and more popular. The quality of the vehicle determines fuel consumption. Lightweighting the vehicle body can significantly reduce the weight of the vehicle, and the fuel usage can be significantly reduced. If the car body needs to be lightweight, it must be made of aluminum alloy.

What is the resistance value if the surface of the workpiece is not cleaned during resistance welding?
When welding with a resistance welder, the surface of the workpiece must be kept clean. If rust, oil stains and other contaminants are not cleaned, it will produce great resistance, resulting in defects such as incomplete welding and weak welding.

One trick to see the differences between pneumatic spot welders with large price differences
The prices of pneumatic spot welders on the Internet vary widely. As a buyer, you need to click on them one by one to take a closer look at the prices. Many of the low prices are deposits, some are introductory prices (a strategy to divert traffic), some have very small power and the workpieces welded are very thin.
