What is an automotive spot welder?
Spot welder is the most common welding machine used when welding sheet metals or wire mesh. The typical application of spot welder is in the automobile manufacturing and repair industry for welding sheet metals to form or repair car bodies.
Is spot welding used on cars?
Spot welding is an economical method for joining metals that is commonly used in car manufacturing plants. The method is adaptable to high speed automation and is under strict cycle times. The plants are usually fully automated and equiped with robotic cells in which different parts of the chassis are built.
Will arc welding on a vehicle damage electronics?
Electric current flowing through from the welder can damage or short circuit electrical components. Also make sure to remove any modules, batteries, sensors, wires and other electronic components from the welding area.
What do you need to spot weld?
Spot welding uses the heat from an electrical current to join 2 pieces of metal quickly, and is typically used for joining sheet metal. It’s also easy to do with a spot welding machine, which has 2 electrode tongs about 6 inches (15 cm) long that pass an electrical current through the metal to fuse them together.
How do I prepare for a spot welder?
5 Things To Do Before Spot Welding a Vehicle
- 1: Clean The Electrodes.
- Carry Out a Test Tag.
- Observe Manufacturers Methods.
- Prepare Spot Weld Areas.
Is it easy to spot weld?
Should I disconnect battery when welding on car?
Make sure the battery is disconnected and all systems are shut down before the welding process. Electric current flowing through from the welder can damage or short circuit electrical components. Also make sure to remove any modules, batteries, sensors, wires and other electronic components from the welding area.
Should you disconnect alternator when welding?
“When welding, there is a danger that electrical components will be damaged by the electrical current flowing through the body. Before starting work, disconnect the negative terminal of the battery and ground the welder near the welding location of the body.”
What is the thickness of sheet metal on a car?
Automotive sheet metal once ran in the range of 18-gauge, which was 48 thousandths of an inch thick (actually 0.0478 inch). 20-gauge became common in more recent times, and this meant 0.0359-inch-thick metal—still a lot to work with in-bumping and metal finishing.
