What tool is used to check internal misalignment between two sections of pipe to be welded end-to-end? protractor Hite gauge torpedo level combination square

## Step 1<br />The problem is asking for the tool used to check the internal misalignment between two sections of pipe that are to be welded end-to-end. This is a common task in welding and fabrication, where precision is key to ensure a strong and secure weld.<br /><br />## Step 2<br />The options provided are a protractor, a Hite gauge, a torpedo level, and a combination square. Each of these tools has a specific use in construction and engineering.<br /><br />## Step 3<br />A protractor is used to measure angles, a torpedo level is used to check the level of a surface, and a combination square is used for a variety of tasks including measuring angles and checking the level of a surface.<br /><br />## Step 4<br />A Hite gauge, also known as a pipe gauge, is used to measure the internal diameter of pipes. This makes it the most suitable tool for checking the internal misalignment between two sections of pipe.
