Welding Quizzes Online & Trivia

Th correct answer to this question is D, the coating products a protective gas to prevent porosity. Stick welding, also known as shielded metal arc welding is a manual technique, which uses electrodes covered with flux to lay the weld. This technique was invented by Nikolay Slavyanov in 1888 and patened by C. L. Coffin in 1890. Preventing porosity is a very important concern when welding. This is because porosity can weak the weld. Along with the electrode, a power supply is necessary for welding. Like other welding methods, stick welding can be dangerous and precautions should be taken when using this technique.

Welding is both an art and an occupation where a welder will use a device similar to a torch to fuse metal. There may be two pieces of metal together, so he will use the light to blend it. The welding may be doing gas metal arc welding. He also may use a MIG welder, which is the same as the gas metal arc welding. The welder uses electrodes. The gas is shielded. The MIG welder may use different types of metal, and he will not just use one kind of metal. Therefore the two items on MIG welder that he would need to be changed would be the contact tip and shroud. These would allow the change in electrodes.

All of the above

Areas that have less than 10,000 cubic feet per welder, or that have ceilings less than 16 feet high, require forced ventilation.    

IT SHOULD BE WELDING HELMAT AND SAFETY GOOGELS; MEAN WHILE THIS IS SAYING THAT PARTICULARLY FOR THE EYES

The answer should allow for other words that mean the same as explosion

A gas that does not chemically react with other elements to help produce a quality weld.

The correct answer to this question is D, Oil. Gas cylinders can hold oxygen under pressure. If mixed with oil, the bottle can explode or start a fire, causing injury to property and humans. Regulators are control valves. These valves reduce the input pressure of a fluid. This reduction goes to the value one wishes the output to have. Regulators are used with liquids and gases. If used with oil, it can also cause a fire. Gas hoses are used in welding and cutting metal. A twinned or double tube would join oxygen and fuel hoses together. Like the cylinders and regulators, these hoses coming in contact with oxygen can cause severe damage.

The answer to this is the regulator. There are a lot of people who need to do welding whenever there are two pieces of metal that need to be connected to each other. If the welding’s flame is too strong, it may not provide what people are expecting. If the flame is also too low, it will not have the ability to connect the two pieces of metal with each other. If you are planning to do some welding, get to know the various tips on how to do it properly. Safety tips can be very helpful and at times, the tips may even save your life.

This is not true you must wear one. With welding oxyfuel without a low shade lens you can develop cateracts

It should be 1 second per every 10 amps you are using to weld.
