Spot welding is known as resistance welding because the the two pieces of metal melt together at the point of highest resistance to current flow, basically when the electricity flows through the pieces it heats up at the point of highest resistance that is where where the metal pieces touch and in a direct line from the two contact tips on the spot welder. Simple!
What else can I help you with?
What type of welding machine use in spot welding or resistance welding?
Mainly In spot welding & resistance welding two type welding machines are used :- 1. Air Cooled & 2. water Cooled.
When was the spot welder invented?
Spot welding is a form of resistance welding invented by Elihu Thompson in the late 1800s.
What is the temperature of resistance spot welding?
Resistance spot welding typically occurs at temperatures between 1,800 and 2,500 degrees Celsius at the welding point. The high temperature is generated due to the electrical resistance between the workpieces, causing them to melt and fuse together.
Difference between ERW and SAW welding?
SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
What welding process uses a resistive heating system to achieve metal deposition?
The welding process that uses a resistive heating system for metal deposition is known as Resistance Welding. In this process, electrical resistance is utilized to generate heat at the interface of the materials being joined, which causes them to melt and fuse together. This method is commonly used for spot welding and seam welding, particularly in the automotive industry for joining sheet metal components. The efficiency and speed of resistance welding make it suitable for high-volume production.
Resistance welding is commonly used in production welding operations?
Yes, resistance welding is used in production welding. It is used extensively in the automotive industry.
What has the author Hongyan Zhang written?
Hongyan Zhang has written: 'Resistance welding' -- subject(s): Electric welding 'Resistance welding' -- subject(s): Electric welding
What is resistance welding?
Arc. It's where electrical resistance is used to create the heat for the welding process.
What is the purpose for welding with direct current?
spot welding is one reason
Why spot welding robot not used in arc welding?
A spot welding robot has generally 5 axis opposed to an arc welding robot that needs 6 axis. The controls and communication channels with the welding power supplies are configured differently as well.
What is the difference between arc welding and resistance welding?
Arc welding uses an electric arc to melt and join metal pieces together, while resistance welding uses heat generated by the resistance to electric current flow between two metal pieces to join them together. Arc welding is more versatile and can be used for various types of metals, while resistance welding is more suited for high-speed production and is commonly used in automotive and appliance manufacturing.
What is the bonding together of two types of metal using an electric current?
The bonding together of two types of metal using an electric current is known as "electrical resistance welding." This process involves applying heat generated from electrical resistance at the interface of the two metal pieces, causing them to fuse together. Typically used in manufacturing, methods like spot welding and seam welding are common applications. The technique is efficient for creating strong, durable joints without the need for additional materials like adhesives or fillers.
