Why test for polarity in welding?
Different material welds differently depending on polarity. There are also different types of welding rods, so polarity must be tested.
How does welding damage eye sight?
An electric welding arc produces ultraviolet light and the UV light will damage the retina. With a good welding helmet, your eyes will be protected, but you must have the proper shade (somewhere between 9 and 14 depending on your amperage) and if using an auto-darkening helmet, it must switch on quickly. (1/25000 of a second)
What is arc welding answer?
Arc welding is a type of welding using electricity to heat and fuse metal together. In order to control the process the heat must be controlled by varying the current. MIG (Metal Inert Gas) welding uses an inert cast to protect the weld from the air at extreme temperatures during the welding process.

Why must the ends of a pipe be beveled before welding?
Beveling the ends of a pipe before welding is essential to ensure proper penetration of the weld and to create a strong joint. This preparation allows for better fusion of the base metals, reducing the risk of defects such as incomplete penetration or weak spots in the weld. Additionally, beveled edges facilitate the alignment of the pipes and improve access for the welding torch or electrode. Overall, beveling enhances the structural integrity and longevity of the welded joint.
How is the root opening size determined in welding?
the root opening is the distance between joint members at the root of the weld before welding. the root opening must be accurate so that excess welding is not necessary.

Why must metal that has been used before be cleaned prior to welding?
Metal that has been used before must be cleaned prior to welding to remove contaminants such as rust, dirt, oil, and paint, which can negatively affect the quality of the weld. These impurities can lead to poor fusion, increased porosity, and weakened joints, compromising the overall integrity of the welded structure. Cleaning ensures better penetration of the welding material and promotes stronger, more reliable welds. It also helps in achieving consistent and uniform heat distribution during the welding process.
Why is a transformer rectifier often prefferred for smaw?
SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.

Selecting an Accredited Welding School?
Attending welding school and earning a welding license can qualify graduates for many job opportunities. Before enrolling in a welding school, students should verify that the school is accredited and prepares students for licensing by the American Welding Society. Students must attend accredited schools in order to qualify for welding licensing exams, receive their licenses and have prospective employers recognize their academic achievements as valid. Accredited schools have passed an evaluation of the quality and consistency of the education they provide, ensuring that their students learn the skills they need to become professional welders.
